氧传感器使用说明书(详细版)

PE CS/CCS系列氧探头使用说明书使用前务必仔细越多！1．准备：1.1 要确保氧探头顶部锆头部分运输安全，因此有一个塑胶部件用来代替原有的锆件，通过旋开外管，可以拿下塑料元件已安装原来的锆件。

锆件将放入一个小的塑料容器内运输，他将被装进测量单元的终端连接盒。

如果氧探头交付，准备安装，你会发现一个随附的包装，即以上说明的这一点。

注意：陶瓷外管和锆件上的安装孔是不对称的，可以通过轻微的旋转调整，使它们安装到一起。

在除去塑胶部分安装好锆件后，外管必须逆着弹簧压力旋回。

注意：1.1是探头出口包装的首选的方法。

CCS 2000型准备交货安装时锆件已不能移动。

1.2 氧探头使用必须提供参比气，氧探头有连接参比气的接口。

参比气可以从ESS-ELECTRONIC单元提供，但事先要用硅胶管将其与接氧探头连接起来。

我们建议硅胶管型4 × 1,5或3 × 1,5 。

如果需要烧炭功能（几乎所有渗碳气氛都是必要的），供气单元可以提供一定量的必要的烧炭气体。

更多信息查询5.22，5.23。

2. 氧探头的插入和安装氧探头可以直接插入热炉内，需要的步骤描述在（1）内一定要小心太热和易燃的炉内气氛外泄。

这些气体有毒或具有潜在的危险。

2.1使用软管连接参比气到氧探头，通过调节参比气流量，使参比气值流量大约为5－10l/h。

2.2连接控制器的两个插头（圆柱形，银色的接头，一个热电偶，一个为测量电压）。

一般配置如下：探头电压：2极插头，1为正，2为负；温度：4极插头，4为正，3为负；电机：5极插头，1，2和PE。

2.3连接运行电压适用于机械装置旋转，使用红色直角连接器（电机缓慢旋转—每小时2圈－几乎看不到）。

2.4从控制器的显示中观察升温及电压上升。

2.5当炉温达到要求，氧探头准备工作，有可能测量电压读数显示值过低或者过高。

这是一些残留污物蒸发的结果（油污等），正常情况通常在2－3小时后停止。

2.6必须控制正确的参比气流量。

氧传感器的使用说明(详细版本)。

.氧传感器(四线芯片型)说明手册1。

概述氧传感器是现代发动机管理系统中必不可少的重要部件。

它用于检测汽车发动机排气管内燃烧废气中的氧含量，从而确定发动机的实时空燃比状态。

根据不同的氧浓度，传感器会向发动机电子控制模块输出不同的电压信号，作为系统闭环燃油修正补偿控制的重要依据。

由于氧传感器的应用，发动机在大多数工况下都能工作在理想的空燃比状态，从而获得良好的排放特性和燃油经济性。

该公司的加热型氧传感器体积小、起燃快，使发动机管理系统能够尽早实现系统的闭环燃料管理控制。

图1氧传感器2的外观。

工作原理氧传感器采用扁平结构的多层氧化锆陶瓷作为核心元件。

氧化锆元素的工作原理相当于一个简单的固体原电池。

根据电化学原理，由于氧离子浓度的不同，两侧电极之间会存在电位差。

由于外电极暴露于废气，氧离子浓度将根据实际工作条件而变化，而内电极是参考空气，并且氧离子浓度是恒定的。

当发动机的空燃比稀时，排气中的氧离子浓度相对较高，并且内电极和外电极之间的氧离子浓度差小，即电势差小，并且氧传感器的输出电压信号接近0V。

相反，当空燃比浓时，排气中的氧离子浓度相对较低，并且内电极和外电极之间的氧离子浓度差大，即电势差大，并且传感器的输出电压接近1V。

The sensor evaluation in % therefore e can only be taken as a relative measure. An evaluation of 70% does not mean that 70% of lifetime is left, but that the electrode signal has 70% of a good state reference.Note: The sensor state evaluation will be stored after a successful calibration of the oxygen sensorThe nominal lifetime may be reduced due to the application. Negative effecting are:- Extreme storage and operation temperature- D irty water during measuring- Mechanical stress to sensor membrane- Dry storage of filled sensor- Permanent use at higher CO 2-concentrationsMounting/Operation Position:The optimum position is with sensor membrane pointing downwards.Measuring Precision: The precision can be influenced due to:- To less flow- Water and sensor temperature have to be the same, most exact measuring is done, when calibrated at measuring temperature.Generalfilling hole shaft membrane head platinum elec-trode protective flask The oxygen sensor is an active sensor. It consists of a platinum cathode, a lead an-ode and potassium hydroxide (KOH) as an electrolyte. If oxygen is present, it is re-duced on the platinum cathode and the sensor delivers a signal. If no oxygen is pre-sent, no signal is delivered. The anode is consumed by the oxygen measurement.The sensor ages. Furthermore, the sensor loses liquid through the permeable mem-brane, in particular, when it is stored in dry air. Therefore, it should be checked andmaintained regularly and replaced as necessary. (p.r.t. sensor maintenance)Make it a rule to always store the electrode in a humid environment- in the storage flask filled with water or- in another container filled with waterIf electrode has not been used for some time, clean membrane with softcloth and remove deposits, if any (algae, bacteria etc.).Attention: The membrane is delicate – if damaged, caustic electrolytegets lost and the sensor shows wrong signal. DesignThe electrode housing is made of ABS. With the exception of the electrode shaft all parts need to be maintained regularly and be replaced if necessary. o Protective flask : The protective flask is used to moisten the membrane. This prolongs service life of the electrode. The protective flask contains water. Attention ! Use water only; never use potassium chloride (KCI); this is only re-quired for storage of pH-electrode.o Membrane head : the membrane head is covered with a Teflon membrane. It will be filled with KOH electrolyte and screwed onto the electrode shaft (no airbubbles). Damages in the membrane, large air bubbles or air bubble rings in the membrane head will result in erroneous measurements. This may also be the rea-son for errors in the calibration.The membrane head (GWOK 02) is a spare part and can be ordered individually. o Filling hole : If the electrode is used at high temperatures or if it has been stored without its protective flask for a longer period of time, some electrolyte will be lostdue to evaporation. Please refer to Refilling description below.DANGER Attention when working with electrolyte: The electrolyte is caustic! (strong base, KOH) Avoid contact to skin, protect Your eyes !Visible Residues in the Inner of Membrane Head:As a reaction product in operation, there will be lead oxide (red and brown – from the reaction with oxygen) and lead carbonate (white – from the reaction of carbon dioxide) in the inner of the sensor.These substances may accumulate visibly at the membrane, but usually have now negative effect on the operability. Within a maintenance cycle the residues can be washed off the membrane nearly completely.Significant deposits on the membrane and matt platinum electrode.Deposits already have an effect on the measurement.=> Carry out maintenance to remove these.Slight deposits on the edge of the electrode, predominantly blank platinum elec-trode.No significant influences on the measurement to be expected.=> Maintenance not absolutely necessary.Deposits on the membrane, bare platinum electrode.=> no maintenance required.Polished platinum electrode during maintenance.Before screwing the membrane head on sensor body again they should be washed off, to avoid them getting in be-tween platinum cathode and membrane.A fast occurrence shortly after first filling or an unusual high amount of them (e.g. within some days) may be a sign of air in the sensor – either because of incorrect filling (bubbles), not sufficiently closing membrane head or filling screw or a leaking membrane.First start of operation of dry sensor GWO 5610 / Refilling of GWO 5610The GWO 5610 can be delivered dry as an option. Therefore the sensor is easily storable over a long time.The sensor has to be filled timely towards the measuring. After filling a time of ~ 2 hours has to be considered, until the sensor has stabilized.Wear suitable gloves*) and protect your eyes with safety goggles when filling the electrolyte!Do not touch the electrolyte with bare skin, if there was contact rinse sufficiently with water.Material:∙Sensor GWO 5610 with membrane head∙Filling-pipette∙Electrolyte KOH∙Flat blade screw driver∙Paper towel∙Suitable gloves *), safety goggles∙Wash basinFirst Filling:∙Check membrane head GWOK 02: is it in good state? Is Mem-brane undamaged?∙Open filling screw∙Fill pipette with KOH∙First fill the membrane head up to ¾ of its height, screw onmembrane head tightly, rinse excess KOH with water.∙Then carefully fill the sensor, try to flick at the shaft from time totime, helping air bubbles coming out. In sum the sensor fillingtakes around 5 ml.∙If there are no more air bubbles and the filling hole is full, closewith filling screw.∙Rinse excess KOH with waterFigure: Filling with pipette ∙Turn sensor upwards: Are air bubbles visible below the mem-brane? If so: Refill once again.∙Wait approximately 2 hours for the sensor to stabilize, afterwards calibrate the sensor – the electrode state evaluation should deliver 100%.*) suitable gloves: Acc. to DIN EN 420, e.g. natural latex, natural rubber, butyl rubber, nitrile rubber,polychloroprene, fluorinated rubber.Sensor Maintenance of GWO 5610If the sensor can no more be calibrated or only unstable values are displayed, it has to be maintained or even or the membrane head has to be exchanged.Wear suitable gloves*) when filling the electrolyte! Do not touch the electrolyte with bare skin. If there was contact rinse sufficiently with water.Material:∙Sensor GWO 5610, eventually spare membrane head GWOK 02∙Filling pipette∙Electrolyte KOH∙Flat blade screw driver∙Paper towel∙Polishing foil (pink)∙Suitable gloves *), Safety goggles∙Wash basinMaintenance is basically the same as the first filling, but first the membrane head is unscrewed and the old electro-lyte is removed.Unscrew the membrane head and the refill opening - Attention! Old electrolyte will now leak out!If the membrane is undamaged and free of deposits, the membrane head can be used again.The platinum electrode must be bright and free of deposits!Wipe off existing deposits from the platinum electrode with a cloth, if necessary polish the electrode using the pink polishing foil.The filling of the sensor is like described bevor.Hints for Operation:a.) Treat device and sensor carefully. Use only in accordance with above specification. (do not throw, hit againstetc.). Protect plug and socket from soiling.b.) The electrode are only suitable for the devices GMH5630, 5650. Unsuitable devices may lead to the destructionof the measuring device and the oxygen sensor.c.) A protective cap, such as GSKA 3600 in plastic or GSKA 3610 in red bronze is recommended for protection ofthe membrane, e.g. for use in bodies of water.Safety guidelines:This device has been designed and tested in accordance with the safety regulations for electronic devices. However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and special safety advises given in this manual will be adhered to when using the device.1. Trouble-free operation and reliability of the device can only be guaranteed if the device is not subjected to anyother climatic conditions than those stated under "Specification".2.

氧传感器使用说明书 （第一版）适用零件号：25327985 253599081.概述氧传感器是现代发动机管理系统中必不可少的重要零部件。

它是一种利用电化学工作原理发展出来的电器元件。

氧传感器在现代发动机管理系统的配置机构中被用于探测汽车发动机所排出的燃烧废气中氧的含量，借以判定发动机实时燃油供给空气燃料混合比的实际状态，并通过自身产生的电器反应信号反馈给发动机电子控制模块（ECM），以作为系统燃油管理系统的闭环燃油修正补偿控制的重要依据，使燃油管理子系统能够更加精确地控制调整发动机各种工作状态下的空气燃料混合比；并在绝大多数工况下使系统保持在理想空燃比工作状态，以便获得更加优良的汽车排放控制特性和燃油经济性。

氧传感器的输出信号为0 ~ 1V的交变电压信号。

传感器可根据发动机所排燃烧气中氧的含量高低自动感应和探测并向发动机电子控制模块输出这一高低变化的电压信号。

现代发动机管理系统采用的氧传感器有两种主要类型：非加热型氧传感器和加热型氧传感器。

装配在发动机排气歧管上的氧传感器，由于可以利用发动机所排出燃烧废气的余热进行快速加热，故可使用价格低廉的非加热型氧传感器；当氧传感器的安装位置受到整车布置限制，氧传感器距离发动机排气歧管出口较远时，由于不能利用发动机燃烧废气对于传感器迅速加热，此时必然需要采用加热式氧传感器。

加热式氧传感器的内部设计有热敏电加热元件，可利用系统供电电压强制使氧传感器加速预热，促使其快速起燃，及早实现系统的闭环燃油管理控制。

2. 工作原理德尔福公司生产的氧传感器是采用氧化锆元件作为传感器的基础元件。

氧化锆元件是一种通体充满无数微孔的陶瓷基础元件外面镀有氧化锆涂层，该涂层外测暴露于发动机燃烧废气之中；涂层的内侧透过含微孔的陶瓷元件与大气相通。

集中在氧化锆内外两侧电极之间氧含量的差别形成的微分电压信号。

当氧化锆元件被电流加热或被流经传感器的发动机燃烧废气加热所激活，空气经过通体充满无数微孔的陶瓷基础元件进入氧化锆元件的内电极，而燃烧废气流经氧化锆的外电极。

In the most cases, however, the sensor must be dismounted for a calibration in air.When dealing with biotechnological processes which require sterile conditions, the sensor cannot be removed for calibration. Here, calibration must be performed with aeration directly in the process medium (e.g. after sterilization).The calibration procedures for these two common applications are described on the following pages. Of course, other combina-tions of process variable and calibration mode are possible.Note:When a 2-point calibration is required, the zero point calibration should be performed prior to saturation or concentration cali-bration, resp.All calibration procedures must be performed by trainedpersonnel.Zero point calibrationNote:In Hold mode the controller output acts as configured (Y = const. or Y = 0).50 %X w10 / (1.00)20 / (2.00)30 / (3.00)40 / (4.00)50 / (5.00) ControlleroutputYProportional action (Gradient K C[%])Neutral zone (Y=0)Tolerated deviation from setpoint.The setting “010%”, for example, permits a deviation of ±5 % from the desired value without activating the controller.Pulse length / pulse frequency controllerPulse length controller (PLC)The pulse length controller is used to operate a valve as an actuator. It switches the contact on for a time that depends on the controller output. The period is constant. A minimum ON time of 0.5 sec is maintained even if the controller output takes corresponding values.Pulse frequency controller (PFC)The pulse frequency controller is used to operate a frequency-controlled actuator. It varies the frequency with which the contacts are switched on. The maximum pulse frequency [pulses/min] can be defined. It depends on the actuator.The Contact ON time is constant. It is automatically calculated from the user-defined maximum pulse frequency:Output signal (switching contact) of pulse frequency controllerOutput signal (switching contact) of pulse length controllerOperation with automatic cleaning system“EasyClean” is a separate automatic cleaning system. The cleaning cycle is activated according to the cleaning interval defined during configuration (Pg 55).Calibration error messagesNoteThe worsening of a Sensoface criterion leads to the devaluation of the Sensoface indicator (Smiley becomes “sad”). An improvement of the Sensoface indicator can only take place after calibration or removal of a sensor defect.SensocheckContinuously monitors the sensor and lines for short circuits or open circuits. Critical values make the Sensoface “sad” and the corresponding icon flashes:The Sensocheck message is also output as error messageErr33. The alarm contact is active, the red LED is lighted, out-put current 1 is set to 22 mA (when configured corresponding-ly). Sensocheck can be switched off during configuration (then Sensoface is also disabled).

Otherwise, the assembly may not be insert into the process.4.2PolarizationThe sensor was tested in the factory for perfect functionality and is supplied ready for operation.To prepare for calibration, proceed as follows:1.Remove the sensor protective cap.2.Place the externally dry sensor in atmospheric air. The air should be saturated with watervapour. Therefore, install the sensor as close to the water surface as possible. Whencalibrating the sensor membrane, make sure the membrane remains dry. Therefore, avoidany direct contact with the water surface.3.Connect the sensor to the transmitter and switch on the transmitter.4.Switch-on the transmitter.If you connect the sensor to the transmitter Liquisys M COM223/253, polarisation isautomatically performed after switching on the transmitter.5.The polarisation time takes about 1 hour.!Note! Polarisation starts high, then drops gradually. You will recognise the end of polarisation when the display stabilises and remains practically constant."Caution!•When you remove the sensor from the medium, protect the sensor from strong sunlight.•Make sure you comply with the instructions for commissioning and calibration in theOperating Instructions of the transmitter.4.3CalibrationCalibrate the sensor (calibration type "Air") immediately after it’s polarization.1.Remove the sensor from the medium.2.Clean the outside of the sensor with a damp cloth. Then dry the sensor membrane e.g.by using a tissue.3.If the sensor is removed from a closed pressure system with a process pressure greaterthan atmospheric pressure:–Open the membrane cap to equilibrate the pressure and clean the cap if necessary.–Replace the electrolyte filling and close the membrane cap again.–Wait for the polarisation time to end.4.Then wait while the sensor adjusts to the temperature of the ambient air. This takesabout 20 minutes. Check that the sensor is not in direct sunlight during this time.5.If the measured value display on the transmitter is stable, carry out the calibration inaccordance with the Operating Instructions of the transmitter.6.Place the sensor in the medium again.!Note!Make sure you comply with the instructions for calibration in the Operating Instructions of the transmitter./worldwideKA284C/07/en/06.05Printed in Germany / FM+SGML 6.0 /DT71002048。

1.概述氧传感器是现代发动机管理系统中必不可少的重要零部件。

它用于探测汽车发动机排气管中燃烧废气中氧的含量,借以判定发动机实时空燃比状态。

根据氧浓度的不同,传感器将输出高低不同的电压信号给发动机电子控制模块（ECM）,作为系统闭环燃油修正补偿控制的重要依据。

由于氧传感器的应用，发动机能在绝大多数工况下工作在理想空燃比状态,从而获得良好的排放特性和燃油经济性.本公司加热式氧传感器尺寸小巧，起燃迅速,可使发动机管理系统及早实现系统的闭环燃油管理控制。

the quenching principle of excited fluorescence by specific substances in physics.The blue light emitted by the light emitting diode(LED)irradiates on the fluorescent substance on the inner surface of the fluorescent cap,and the fluorescent material on the inner surface is excited and emits red light.by detecting the phase difference between the red light and the blue light and comparing it with the internal calibration value,the concentration of oxygen molecules is calculated, and the final value is automatically compensated by temperature.●No electrolyte is required and will not be polarized.●No oxygen consumption,not affected by flow rate.●Built-in temperature sensor,automatic temperature compensation.●Free from interference by chemicals such as sulfides●Small drift,rapid reaction,more accurate measurement.●Maintenance-free,long service cycle,lower cost of use.●Simple replacement of fluorescent capⅡ、Technical performance and specifications1.Technical parameterModel

of the film head.The attachment of sediment should be avoided in the part of membrane head.2.Electrical connection●Red wire-power cord（12～24V）●Black wire-ground wire（GND）●Blue Line-485A●White Line-485B●Bare wire-shield layerAfter the wiring is completed,it should be carefully checked to avoid the wrong connection before the power is turned on.Cable specification：Considering that the cable is immersed in water(including sea water)or exposed to air for a long time,the cable has a certain corrosion resistance.All interfaces of cable outer diameterΦ6mm,have been waterproof.Ⅳ、Maintenance1.Maintenance schedule and methodology1.1Maintenance scheduleDifferent from the dissolved oxygen probe technology of electrochemical principle,the fluorescence dissolved oxygen probe does not consume oxygen and does not need to be cleaned frequently(except when it is used in viscous liquid).Maintenance task Recommended maintenance frequencyCleaning sensor Wash every30daysCheck for damage to sensors andfluorescent caps Check every30daysReplace the fluorescent cap Replace it once a yearCalibrate sensors(if required by the competent authority)）According to the maintenance schedule required by the competent departmentNote:The maintenance frequency in the above table is only recommended,and the maintenance personnel shall clean the sensor according to the actual use of the sensor;however,the replacement frequency of the fluorescent cap is recommended once a year.1.2Maintenance methodSensor outer surface:clean the outer surface of the sensor with tap water,if there is still debris residue,wipe with wet soft cloth,for some stubborn dirt,you can add some household washing liquid to tap water to clean.a)External surface of fluorescent cap:remove the protective cover at the front end of the sensor,rinse the dirt on the optical window of the sensor with clean water,and finally cover the cover;If wiping is required,please use a soft cloth and take care of force and force direction;If the fluorescent film layer is scratched,the sensor will not work properly.b)Inner surface of fluorescent cap:if water vapor or dust invades the inside of fluorescent cap, the cleaning steps are as follows:●Remove the fluorescent cap；●Rinse the inner surface of the fluorescent cap with tap water；●For dirt containing fat and oil,clean with warm water with household washing fluid；●Rinse the inner surface of a fluorescent cap with deionized water；●Gently dry all surfaces with a clean velvet-free cloth and put it in a dry place for the moisture to evaporate completely.c)Check the cable of the sensor:the cable should not be tightened when it is working properly, otherwise it is easy to break the wire inside the cable and cause the sensor to fail to work properly.d)Check that the shell of the sensor is damaged by corrosion or other causes.e)Daily preservation of fluorescent caps:when not in use,put in a shield with a wet sponge to keep the sensor moist for a long time.If the head of the sensor fluorescent cap is dry for a long time, it will produce the drift of the measurement results and need to be immersed in water for48hours before use.2.Frequently questionsWrong Probable cause SolutionThe operating interface cannot connect or does not display the measurementresults Error connecting controllerto cableReconnect the controller and

TEMPERATURE (10)SPARE PARTS (11)Part 1 - IntroductionA new modular dissolved oxygen sensor is now being supplied for replacement and upgrade of DOTX-45 D.O. monitoring systems. The new sensor provides the advantages of the original modular sensor with the economy of a rebuildable module that greatly reduces the operating cost of the system.The new sensor is designed to interface with the DOTX-45 transmitter electronics without adjustment. All that’s required is to remove the original DOE-45P sensor from it’s mounting assembly and install the new sensor in its place. On units with software version V2.05 or earlier, Tear Diagnostics should be turned OFF. Figure 1 below shows the typical installation of this sensor with the DOTX-45 monitor.Operation of the DOTX-45 monitoring system does not change. Refer to your DOTX-45 manual for instructions on calibrating the system once installation of the sensor is complete.Figure 1-1 D.O. SYSTEM DIAGRAM WITH SUBMERSIBLE SENSORPart 2 – Electrical ConnectionThe replacement sensor has the same number of wire connections as the original sensor but the color code is slightly different. Figure 2 and Figure 3 shows the proper connection of the sensor to the transmitter. Note that the new sensor no longer contains a yellow conductor. This has been replaced with either a brown or an orange conductor.Figure 2-1 SUBMERSIBLE SENSOR WIRING DIAGRAM2.1 D.O. SENSOR ASSEMBLYThe oxygen sensor is shipped dry. It will not operate until it is prepared by adding electrolyte and a membrane. Preparation of the sensor for operation must be done carefully. The procedure should be done by a qualified technician, and it should only be done when the system is ready for operation. Until then, it is best to leave the sensor in the condition in which it is received.Submersible oxygen sensors are made up of two separate parts, a submersionholder that also contains the temperature compensating element and a sensingmodule. The sensing module screws into the holder, with an o-ring providing awater tight connection. Figure 2-2 below shows the assembly.Figure 2-2 SUBMERSIBLE D.O. SENSOR ASSEMBLYSensing modules contain the main measuring components, and are the main component requiring service. Figure 5-2 below shows an exploded view of theD.O. sensing module.Figure 2-3 SUBMERSIBLE D.O. SENSING MODULE ASSEMBLYFollow the procedure below to prepare the D.O. sensing module for operations:1. Unscrew the electrolyte canister from the assembled module and also remove thevent screw from the side of the body.2. Remove the membrane cap from the bottom of the canister and discard theprotective membrane. O-rings are contained in grooves on both the bottom and top of the canister. Be sure that these o-rings remain in place.3. From the package of membranes supplied with the sensor, place a new membraneinto the membrane cap. The membrane is the clear plastic disk and is separated from other membranes by a paper spacer.4. Screw the membrane cap onto the canister until you feel the o-ring compress. Handtight compression is all that is needed. Do not use tools to tighten. The membrane should be flat across the bottom of the canister without wrinkles.5. Fill the canister with electrolyte until the level reaches the bottom of the internalthreads in the canister.6. Slowly screw the canister onto the sensor body. A small amount of electrolyte willrun out of the hole from which the vent screw was removed. Place a paper towel around the sensor to absorb the electrolyte overflow. The electrolyte is slightlycaustic and should be rinsed off of skin if contact occurs. Tighten the canister until the o-ring at the top of the canister is compressed. Once again, do not use tools to tighten.7. Shake excess electrolyte from the vent hole on the side of the sensor and replacethe vent screw.The sensing module is now ready for operation. The membrane should be stretched tightly across the tip of the sensor.CAUTION: When handling the assembled sensor, do not set the sensor on its tip or damage to the membrane will result. Severe impacts on the tipof the sensor from dropping or other misuse may cause permanentdamage to the sensor.Part 3 - MaintenanceThe DOE-45 Dissolved Oxygen Monitor will generally provide unattended operation over long periods of time. With proper care, the system should continue to provide measurements indefinitely. For reliable operation, maintenance on the system must be done on a regular schedule. Keep in mind that preventive maintenance on a regular schedule is much less troublesome than emergency maintenance that always seems to come at the wrong time.3.1 Sensor MaintenanceVirtually all of the maintenance required for operation of the D.O. Monitor is sensor related. The electronics are generally trouble free. They are burned in at the factory and will likely have a problem only if random component failure occurs.Sensor maintenance is required for accurate measurements. The primary requirement is simply to keep the sensor membrane clean. The membrane is a polymer material that is resistant to anything that will be encountered in water streams. However, deposits or biological growth can form on the surface of the membrane, and these deposits will reduce the sensitivity to oxygen. Normally, these coatings can be removed by simply wiping the membrane with a soft cloth or paper towel.Should a coating form on the membrane that does not wipe off, it is best to change the membrane. Chemical cleaning may work as well, but a new membrane is a more reliable solution. To change a membrane, follow the Sensor Assembly procedure in this manual. Do not reuse the electrolyte from the sensor when changing a membrane. Always refill with fresh electrolyte. The electrolyte is stable and does not have a limited shelf life.Even if no buildup is apparent on the membrane, it should be changed on a regular schedule. The recommended membrane change interval is every 6 months. The actual membrane life is often in excess of one year, but periodic preventive maintenance will simply avoid having to do service on an emergency basis.While the sensor is disassembled for membrane changing, examine the condition of the o-rings on both ends of the electrolyte canister. If the o-rings show any signs of damage, replace them with new ones from the spare parts kit. It is good practice to change these o-rings once a year, regardless of their condition.3.2 LEAD ANODE REPLACEMENTGalvanic D.O. sensors consume the lead electrode during normal operation. As oxygen is measured, lead is converted to lead oxide, and after a period of time, the lead is expended. The lead electrode in Omega’s D.O. sensor can be easily replaced, and replacement should be done automatically every 12 months.The lead electrode is the thick lead wire wrapped around the sensor body see Figure 4. It is connected through a stainless steel post with a nut and star washer. To change the lead electrode, remove the nut and washer and unwrap the old lead. Loop the end of a new lead electrode around the post and replace the nut and washer. Tighten the nut firmly but do not over tighten as damage to the sensing module can result. Wrap the remainder of the lead around the sensor body. There is no need to secure the other end of the lead.D.O. SOLUBILITY VS. TEMPERATURETEMP. D.O.TEMP.

AO-03说明书氧传感器●0~30%线性输出●工作无需外部电源●快速响应●准确可靠●轻便小巧产品简述AO-03氧传感器是一款应用电化学原理测定氧气浓度的传感器，采用模制主体设计，具有响应速度快、准确可靠等特点。

AO-03氧传感器体积较小，便于安装在便携式仪表上，且与同类型的传感器相比性价比更高。

应用范围AO-03氧传感器广泛应用于工业、煤矿、钢铁、石油化工及环保等领域中氧气浓度的检测，如：氧气报警器、空气质量检测仪、商用空气净化器等。

图1.AO-03氧传感器1.传感器规格表1.AO-03技术指标1表格中未标注条件的参数是在推荐电路、20℃、50%RH、1013mBar的条件下对传感器测量所得的结果。

技术指标概述了出厂后前三个月内提供的传感器的性能；2输出信号可能会随时间漂移到下限以下。

2.产品尺寸图图2.AO-03外形尺寸图(单位：mm，针脚公差为±0.05mm，其余未标注公差：±0.2mm)3.安装与使用3.1储存与使用AO-03氧传感器在储存、安装和操作期间需避免暴露于高浓度的有机溶剂蒸汽中。

禁用焊接，因为焊接会引起针脚腐蚀、歪斜、接触不良和造成电解液渗漏等。

在印刷电路板（PCB）上安装AO-03之前，应在安装AO-03之前使用脱脂剂清洗PCB，防止松香等助焊剂杂质挥发凝结堵塞AO-03的透气膜。

禁止在AO-03外壳上使用有机溶剂，因为溶剂可能会导致塑料龟裂。

3.2酸性气体酸性气体（如CO2和SO2）会被电解液吸收，会导致到达电极的氧通量增大，大约每1%CO2增加0.3%氧气信号，因此AO-03不适合在高于25%CO2浓度的情况下连续运行。

3.3使用要求●禁止直接焊接针脚；●初次使用AO-03之前，请至少进行2小时的预热；一旦AO-03工作电极和对电极断开，也需要进行2小时预热；●腐蚀性气体会损坏AO-03，因此不建议在腐蚀性气体环境中使用AO-03；●AO-03的标定需在洁净空气中进行（建议用20.9%的氧气浓度进行标定）；●避免剧烈晃动或者撞击；●避免针脚弯曲和折断；●避免在无氧环境下长时间使用AO-03；●避免在高湿环境下长时间使用AO-03；●请勿破坏AO-03。

To ensure that the new O2sensors work smoothly under process conditions of diverse or even extreme nature, only the highest quality materials have been used to manufacture the sensors.The sensors are equipped with the in-dustrially-proven VarioPin (VP) connector and are ideally suited for use in moist or even wet environments. This connector is absolutely watertight (IP 68), extremely robust, and fully sterilizable. In a test pro-cedure, the VP connector was immersed for 1000 hours in water at 1 bar (14.5 psi) ex-cess pressure (corresponding to a depth of 10 meters). Result: The VarioPin connector remained absolutely impervious.This new range of DO sensors offers a substantially improved set of features. Apart from the above mentioned cableconnection, the differences are primarily to be found in the design of the sensor inner bodies. The special low-ppb version (InPro 6900) has a detection limit of 1 ppb at en-hanced signal stability. This has been made possible by a newly developed annu-lar cathode with protection ring. The basic InPro 6800 can be easily converted/ upgraded to an InPro 6900 version at any time. The inner body of the low-ppb InPro 6900 enables:– lower DO detection limit of 1 ppb accuracy– faultless measurement values evenat fluctuation of flowThe new InPro series of dissolved oxygen (DO) sensors has been specially developed to provide dependable inline measurementsin processes operating under sterile and hygienic conditions.Apart from the basic InPro®6800, an enhanced version is also available to meet higher requirements- the InPro®6900. In both cas-es, durable material and robust construction guarantee high process reliability.A new family of O2 sensorsContents Brewery News 1A new family of O 2sensorsOxygen measurement made easy Sensors for CIP/SIP proceduresMeasurement of oxygenduring CO 2recovery Oxygen and pH measure-ment in wortRepair or replacement?pH measurement in beerMettler-Toledo GmbH Process Analytics Im Hackacker 15CH-8902 Urdorf Switzerland MarComCH-8902 Urdorf, Switzerland Mettler-Toledo GmbH ProzessanalytikD-35396 Giessen, Germany Archive MarComCH-8902 Urdorf, Switzerland andD-35396 Giessen, GermanySubject to technical changes. © Mettler-Toledo GmbH 01/03Printed in Switzerland.IP 68: In an endurance test, the VarioPin connector was immersed in water at 1 bar (14.5 psi) excess pressure (equivalent to a depth of 10 meters). The VP connector proved completely watertight.Brewery News 1METTLER TOLEDOBest materials, well thought-out design: The new O 2sen-sors fulfill even the most rigorous hygiene regulations without difficulty.2No chance of contamination –all hygiene tests passed with flying colorsThe DO sensors have been subject-ed to rigorous trials by leading testing organizations and have stood up success-fully to all challenges. These METTLER TOLEDO DO sensors are the first (and so far only sensors worldwide) with EHEDG and 3-A hygiene certification. Construction and manufacture are both carried out in ac-cordance with the most exacting standards for surface finishing. This ensures com-plete fulfillment of the EHEDG and FDA guidelines relating to smooth surfaces for particularly high standards of hygiene.Validation included:complete traceability of source of steelTogether with every D sensor, METTLER TO LEDO also supplies a 3.1B certificate, standard and free-of-charge.The 3.1B certificate provides evidence of the steel's quality so that those steel parts which come into contact with media can be traced back even as far as the steel produc-er, if need be.Intelligent accessoriesThe O 2Sensor-Master enables fast and simple testing of a sensor prior to its use,and the O 2Sensor-Simulator is specially designed for checking the transmitter andthe cable. For maintenance professionals,these are important aids which make reliable functional tests fast and uncom-plicated.InTap 4000/4004 a fully waterproof portableoxygen analyzer.With the InTap 4000/4004 series, METTLER TOLEDO brings to the market a portable oxygen analyzer ideally suited for use in the beverage industry. Three main features characterize this practical “light-weight” unit - rugged construction, precise measurement and ease of operation. Even under the harshest operating conditions,this fully waterproof instrument consis-tently provides reliable measurement data due to the perfect functional compatibility of the optimized measuring chamber and robust sensor. Neither a fluctuation in flow rate, nor extremely low dissolved oxygen concentrations have any influence on the stability of the measurement results. The North American version of the InTap 4000(InTap 4004) is specially designed with an incorporated quick-connect Zwickel ad-apter, which is a standard connection for North American breweries.The integrated software offers a variety of different functions. Not only is it possi-ble to store the measurement data, but al-so, by using the accompanying “Paraly”software, the data generated are easily transferred to a computer for subsequent processing and evaluation. The data can then be processed either with “Excel” or any other preferred spreadsheet program. A high degree of user ergonomics is built in, such as a menu-driven, step-by-step maintenance routine and many other sim-ilar productivity-enhancing operational features.Due to the modular concept of our oxygen sensors, membranes can be ex-changed in a matter of a couple of min-utes, with little effort. On a practical basis this means that the spare parts for the sensor employed in conjunction with the InTap unit are exactly the same as those used worldwide for the other proven (in-line) oxygen sensors from METTLER TOLEDO. Users are alerted by the Senso-Check function if the sensor needs service attention or the instrument requires (re-)calibration.The oxygen analyzer InTap 4000/4004in its protective housing made of high-impact PU is delivered ready for use, com-plete with a cleaning and conditioning set,all other necessary accessories, and is con-veniently packed in a practical, trans-portable case.Intelligent, mobile oxygen measurement using the InTap 4000.Brewery News 1METTLER TOLEDOPrecise, rugged, simple to useOxygen measurement made easy3Typical measuring solution with retractable housing InTrac 776/777 and Inline O 2 sensors InPro 6800/6900.environment. Over and above this, the sen-sor must be made of FDA-listed materials and be able to withstand scouring in or-der to qualify for unrestricted in the industrial ne sensor that meets these requirements is the new METTLER TO 4-electrode sensor. In addition to perform-ing in such harsh con-ditions, the InPro 7108In numerous beverages such as beer,mineral water or sparkling wine, dissolved CO 2is present in large concentrations. This carbon dioxide content acts as a stimulant as well as having an aseptic effect. The de-gree of purity of the CO 2used has to be checked, since the presence of impurities such as oxygen can have a negative influ-ence on both flavor and shelf life of the product. If the CO 2comes from an outside source, the supplier assumes responsibility for the quality of the gas. In breweries and also in champagne production, the natural CO 2emitted during the in-house fermen-tation process is utilized. The purity of the gas is then a matter for the producer.Measurement of oxygen during CO 2 recoveryMETTLER TOLEDOContamination from oxygen can be extremely well detected by using the proven inline oxygen sensors of the InPro 6800/6900 series from METTLER e of these sensor is not limited to the liq-uid phase alone- reproducible and precise measurement is also possible in the gas phase. This multipurpose functionality makes these sensors an ideal solution for CO 2recovery plants. Uniform design of the equipment and spare parts, such as mem-branes and cables, reduces the learning curve for individuals responsible for oper-ation and maintenance procedures.During preparation of the wort, careful supervision of pH values and dissolved oxy-gen content is an essential factor in con-trolling the flavor of the final product in beer production. In breweries these param-eters are best measured using online sys-tems, whereby the values can be docu-mented and evaluated. When selecting in-line sensors for wort production, it is critical to select systems that function per-fectly at elevated temperatures and in the presence of high solids content. For cost-efficiency, the sensors should also be able to withstand repeated cleaning cycles with hot caustic solutions.Online measurement systems certain-ly pay off, by avoiding the additional labor and time of grab samples followed by lab-oratory analysis. Even more important, often by the time a sample is analyzed in the laboratory the pH or dissolved oxygen content may have deviated from the condi-tions in the controlled process environ-ment. Online measurement ensures per-fect, continuous process documentation. Only in this way is it possible to maintain a consistent and reproducible, high-quality product.The highly valued online sensors of the InPro 6800/6900 series, widely em-ployed for checking the (very low) rest oxy-gen concentration in the final beer, are also extremely well suited for determining the (high) oxygen values in wort. The ro-bust, pressurized InPro 2000 pH electrodes have also proved extremely suitable for measuring pH values in wort.For maximum return on investment and highest operational efficiency, these sensors can be mounted to the process us-ing manual or automated retractableComplete documentation of the pH value and oxygen concentration during wort preparation.housings, which allow withdrawal of asensor from an ongoing process for inspec-tion and calibration. The stringently test-ed, sterilizable double lock system of thehousing allows subsequent reinsertion ofthe sensors under fully aseptic conditions.Oxygen and pH measurement in wortBrewery News1METTLER TOLEDO5Repair or replacement?Fouling of the glass membrane or di-aphragm(s) of a pH electrode has negative effects on the performance of the electrode generally. However, fouling does not always lead to an irreparable defect.Through special cleaning procedures,many electrodes can be restored to a satis-factory operating condition.O xygen sensors too, are subject to a natural aging process and are then no longer able to fulfill the specifications guaranteed at the time of delivery. This is particularly true in respect of the insula-tion resistance of the inner body, which de-teriorates over time due to mechanical andBrewery News 1METTLER TOLEDOthermal stress. One result of a deteriorated inner body is over-range transmitter read-ings. By replacing the inner body, thesensor can be returned to original specifi-cations.Service technicians from METTLER TOLEDO are equipped with sophisticated diagnostic equipment to verify defective sensors and to issue a written report onthe findings. Please contact your local Mettler-Toledo Service office or your local authorized METTLER TO LEDO agent for more information.Our service technicians will be pleased to advise you about suitable O-ring material.Sensors directly in contact with the sample medium are subject to con-tinuous wear and tear, which at some point reaches such an advanced stage that the sensors must be repaired or replaced.6METTLER TOLEDOlaboratory electrode in use.7pH measurement in beerThe pH value of beer is an important quality criterion that has a lasting affect on the taste. As an alternative to mobile sample measurement or test measurements analyzed in the laboratory, continuous measurement directly in the beer processing equipment offers many advantages.Permanent monitoring of the pH value allows continuous product control.The results of in-line measurement are not altered due to sampling errors or through other influences on the sample to be measured.Automatic intervention in the process is possible via the pH transmitter's control functions. Alarm limits can be programmed to prevent filling when the product is outside of a user-defined tolerance range.The use of a pH electrode with integrated temperature sensor allows simultaneous temperature monitoring, and results in correct measurement values through automatic temperature compensation .The appropriate sensorMost successful of all has been a pH electrode with FRISCOLYT ®, a liquid elec-trolyte that is well tolerated with foodstuffs and drinks. Its special composition pre-vents contamination of the electrode,which is a basic prerequisite for correct measurement results. The pH electrode InPro ®2000 is additionally equipped with a Pt100 or Pt1000 temperature probe.Correct installationIn addition to multiple other locations in the process, a final pH check is usually performed just prior to the filling process.Since considerable fluctuations in pressure can occur at this point in the beer line, the pH electrode has to be installed on the in-let side of the pump. The InFit 764-50 CIP housing accepts the pH sensor and allows pressurization up to 6 bar (187 psi). It canbe fitted directly into the beer line via a flange or the INGOLD DN25 weld-in sock-et. Alternatively, there is also a retractablehousing InTrac 776 available, which allows cleaning, maintenance and calibration of the sensor even when the beer feed line is in production. The appropriate measuring device The pH 2100 e transmitter offers a highdegree of performance with very simple op-eration. Calibration, programming and configuration are carried out under menu control in plain language. Four different user levels allow access to only those au-thorized via password number. The backlit display is always easy to read even in poor light conditions. The device corresponds in design, construction and layout to the familiar O 24500 oxygen transmitter that is commonplace in many breweries, i.e. the same instrument philosophy for differentmeasurement parameters. The InPro 2000 pH electrode with liquid electrolyte and integrated temperature sensor guarantees reli-able measurement results.The InFit ®764-50 CIP housing is installed directlyinto the beer line.What are the essential points?Brewery News 1METTLER TOLEDOThe pH transmitterpH 2100 e combines a high degree of performance with ease of operation.Oxygen , conductivity and pH transmitters with PROFIBUS PA interfaceCommunication systems in the field of (process) analytical measurement are moving more and more towards the use of digital technology. The advantages over conventional analog data transfer via 0/4...20 mA lie mainly in the ability, along with the actual measurement signal itself, to exchange additional information between the process control system (PCS)and the analytical measurement device on a two-way communication basis.For some years, METTLER TOLEDO has b een offering transmitters with HART ®Communication which superim-poses a digital signal on the customary 4 -20 mA DC analog signal. This enables the transfer of additional information than just a measurement signal.From now on, transmitter units are al-so available which incorporate a fully dig-ital PROFIBUS PA interface according to the “Profile for Analytical Devices, Version 3”, suitable for measurement of dissolved oxygen, electrolytic conductivity (conduc-tive and inductive) and pH value.Simple connection to the PCS through Plug & Play.Connection to the PROFIBUS DP level is possible either by direct linkage or through a segment coupler. The maximum bit rate of 12 Mbits/s on the DP lane is thereby preserved.The instrument interface employs the FISCO model to ensure in-trinsically safe networks. The ex-isting well-proven functions such as automatic calib ration (Calimatic ®), sensor diagnos-tics (SensoCheck ®) and para-meterization can be accessed via the PCS just as easily and comfortably as before.INGOLDLeading Process AnalyticsMettler-Toledo GmbH Process Analytics Im Hackacker 15CH-8902 Urdorf Switzerland。
