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。
氧气传感器的典型响应曲线如下图所示。

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。

请用户仔细阅读说明书后再使用高温氧探头一、概述高温氧探头是指使用温度在1000℃——1700℃范围内的测氧传感器。
主要是使用在玻璃炉窑,特种陶瓷炉窑,特种钢轧钢炉,真空炉测氧以及其他高温测氧场合。
其他特点是:⑴使用进口焊接式氧化锆传感器,具有良好的密性。
热震性和机械性能。
⑵由于使用温度高,外面的保护管使用刚玉管(一般氧探头使用高温合金管)⑶内外电极采用比较粗的铂金丝来代替镍洛合金丝和管。
所以生产成本比较高。
所以高温氧探头的价格要比一般氧探头高得多。
⑷一般氧探头由于合金管的热胀冷缩,为了保证传感器的良好电气接触性,传感器在弹簧的推力下,可作数毫米的移动,移动间隙可用真空脂或硅橡胶圈密封。
在一般渗碳炉中完全可以实现密封。
而在真空炉中则会发生严重渗漏。
高温氧探头是完全气密的,又可以在1200℃以上的温度中使用,可以适用于真空炉。
(5)高温氧探头有A,B两种。
A:只有一个气路,也就是参比气路(空气含氧量20.9%)B:有两个气路(1)参比气路(空气-含氧量20.9%)(2)标准气路(通入标准气对氧探头进行校对)标准气路相当于一般氧探头的自动除碳气路,由于高温氧探头使用温度很高,如果通入空气燃后温度猛然升高会造成刚玉管和传感器的损坏。
如果通入1%氧含量的标准气,和1PPM 氧含量(百万分之一)的标准气,可以对测氧仪数据进行校正。
一般在工业现场用的高温氧探头都采用A型,因为现场采用标准气校正仪表十分困难。
因为现场很难提供合格的标准气。
现场操作常常采用一根标准氧探头来校队仪表,我们认为标准氧探头是基准,其他氧探头都采用标准氧探头来校队仪表。
过程是这样的,把要校正的氧探头卸下来,把标准氧探头装上去等信号稳定后就可以对仪表进行校正,只有在特定条件下可以采用B型氧探头,如实验等。
二.工作原理焊接时的氧化锆传感器,氧化锆内外两侧分别处在两种不同的气氛中,管子内部通的是参比气(空气含氧量为20.9%)管子外部是放置在炉窑气氛中。
发动机氧传感器套筒使用方法1. 引言嘿,朋友们!今天咱们来聊聊发动机氧传感器套筒,这个名字听起来有点高大上,但其实它在我们日常汽车保养中可是个小能手!别担心,咱们会把这事儿讲得简单明了,让你轻松上手。

3. 使用氧传感器套筒的步骤3.1 准备工作那么,如何使用这个氧传感器套筒呢?首先,准备工作一定要做足!咱们需要一个合适的氧传感器套筒,一般来说,9/16英寸或者18毫米的都是比较常见的。
再准备一个扳手,搞定这两个后,咱就可以开始了。
记得提前把汽车的引擎熄火,安全第一呀,别一不小心变成“火锅底料”了!3.2 操作步骤接下来,咱们就要动手了!首先,找到氧传感器的位置。
通常它是在排气管上,别小看这小东西,它就像藏在角落里的宝藏,需要你费点劲才能找到。
找到之后,先用扳手把连接线拆下来,轻轻松松,别用蛮力,万一弄坏了,那可就得不偿失了。
然后,拿起你的氧传感器套筒,轻轻放在氧传感器上,像是给它穿上一件新衣服,接着用扳手慢慢转动,记得要顺时针哦,别搞混了。
听到“咔哒”一声,那就是它松动了的信号。
轻松转动几圈,直到把它完全拧下来,嘿,恭喜你,成功拆下氧传感器了!4. 更换与安装4.1 新传感器的安装好啦,现在咱要把新传感器装上了。

Underconstant conditions, this flow is proportional to the oxygen content of the medium.This current is converted in the transmitter and indicated on the display as an oxygen concentration in mg/l,as a saturation index in % SAT or as an oxygen partial pressure in hPa.Memosens technology Maximum process safetyThe inductive and non-contacting measured value transmission of Memosens guarantees maximum processsafety and offers the following benefits:•All problems caused by moisture are eliminated.–The plug-in connection is free from corrosion.–Measured value distortion from moisture is not possible.–The plug-in system can even be connected under water.•The transmitter is galvanically decoupled from the medium. The result: No more need to ask about"symmetrically high-impedance" or "unsymmetrical" (for pH/ORP measurement) or an impedanceconverter.•EMC safety is guaranteed by screening measures for the digital measured value transmission.•Application in explosion-hazardous areas is unproblematic; the integrated electronics are intrinsically safe.Data safety through digital data transferThe Memosens technology digitalizes the measured values in the sensor and transfers them to the transmittercontactlessly and free from interference potential. The result:•An automatic error message is generated if the sensor fails or the connection between sensor and transmitteris interrupted.•The availability of the measuring point is dramatically increased by immediate error detection.Easy handlingSensors with Memosens technology have integrated electronics that allow for saving calibration data andfurther information such as total hours of operation and operating hours under extreme measuring conditions.When the sensor is mounted, the calibration data are automatically transferred to the transmitter and used tocalculate the current measured value. Storing the calibration data in the sensor allows for calibration away fromthe measuring point. The result:•Sensors can be calibrated under optimum external conditions in the measuring lab. Wind and weather doneither affect the calibration quality nor the operator.•The measuring point availability is dramatically increased by the quick and easy replacement of precalibratedsensors.•The transmitter does not need to be installed close to the measuring point but can be placed in the controlroom.•Maintenance intervals can be defined based on all stored sensor load and calibration data and predictivemaintenance is possible.•The sensor history can be documented on external data carriers and evaluation programs at any time. Thus,the current application of the sensors can be made to depend on their previous history.2Endress+HauserOxymax COS51DEndress+Hauser 3Measuring systemA complete measuring system comprises:•The digital oxygen sensor Oxymax COS21D •A transmitter, e.g. Liquiline CM42•An appropriate measuring cable, e.g. CYK10•Optional: an assembly, e.g. fixed installation assembly CPA442, flow assembly CPA240 or retractable assembly CPA475InputMeasured variableDissolved oxygen [mg/l, μg/l, ppm, ppb, % SAT or hPa]Temperature [° C, °F)Measuring rangeWiringElectrical connectionThe sensor is electrically connected to the transmitter by means of the special measuring cable CYK10.Example of a measuring system 1Liquiline CM422Measuring cable CYK103Digital oxygen sensor Oxymax COS21D 4Fixed installation assembly CPA442Measuring rangeRecommended operational range COS21D-A0.01 to 20 mg/l 0 to 200 %SAT 0 to 400 hPa 0.01 to 20 mg/l 0 to 200 %SAT 0 to 400 hPa COS21D-B 0.001 to 20 mg/l 0 to 200 %SAT 0 to 400 hPa0.001 to 2 mg/l 0 to 20 %SAT 0 to 40 hPaCOS21D-CSpecial measuring cable CYK10Oxymax COS21D4Endress+HauserPerformance characteristicsResponse timeFrom air to nitrogen at 25 °C (77 °F)•t 90 : < 30 s •t 98 : < 60 s Reference operating conditionsSignal current at air 1)•COS21D-A: 60 nA (40 to 80 nA)•COS21D-B and COS 21D-C: 300 nA (180 to 500 nA)Zero current< 0.1 % of the current in airMeasured value resolution•COS21D-A: 10 μg/l (10 ppb)•COS21D-B and COS21D-C: 1 μg/l (1 ppb)Maximum measured error ±1 % of measured value 2)Repeatability ±1 % of measured value Long-term driftInfluence of medium pressure Pressure compensation not necessary Polarization time•COS21D-A and COS21D-C: < 60 minutes •COS21D-B: < 12 hoursOxygen intrinsic consumption•COS21D-A: Approx. 20 ng/h in air at 25 °C (77 °F)•COS21D-B and COS21D-C: Approx. 100 ng/h in air at 25 °C (77 °F)InstallationAngle of installationReference temperature:25 °C (77 °F)Reference pressure:1013 hPa (15 psi)1) For the reference operating conditions indicated2) In accordance with IEC 60746-1 at nominal operating conditionsZero-point drift:< 0.1 % per week at 30 °C (86 °F)Measuring range drift:< 0.1 % per week at 30 °C (86 °F) 1)1)under constant conditions eachPermitted angle of installationOxymax COS51DEndress+Hauser 5EnvironmentAmbient temperature range –5 to +135 °C (23 to 175 °F)Storage temperature–10 to +60 °C (10 to 140 °F) at 95% relative air humidity, not condensingIngress protectionIP 68 (10 m / 33 ft) water column at 25 °C (77 °F) during 45 days, 1 mol/l KClProcessProcess temperature•COS21D-A and COS21D-C: -5 to 135 °C (23 to 275 °F)•COS21D-B: -5 to 100 °C (23 to 212 °F)Process pressure•COS21D-A: 0 to 4 bar (0 to 58 psi)•COS21D-B and COS21D-C: 0 to 12 bar (0 to 174 psi)Minimum flow rate•COS21D-A: 0.02 m/s (0.07 ft/s)•COS21D-B/C: 0.10 m/s (0.33 ft/s)Mechanical constructionDesign, dimensionsWeight 0.2 kg (0.44 lbs)MaterialCaution!

For further information on the external load resistance and connection to the recommended mating part, please see Operating Principle OP04 or contact Honeywell.PoisoningMediceLs are designed for operation in a wide range of environments and harsh conditions. However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage, fitting into instruments and operation. When using sensors with printed circuit boards (PCBs), degreasing agents should be used before the sensor is fitted. Do not glue directly on or near the MediceL as the solvent may cause crazing of the plastic.Intended UseThese sensors are designed to be used to monitor the partial pressure of oxygen in anaesthesia (not including xenon), critical care, neonatal incubators and general oxygen monitors.Stabilisation TimeAllow at least 15 minutes to stabilise in the instrument before calibration or refer to manufacturers instructions.Cleaning and SterilisationIn case of contamination the sensor may be cleaned with distilled water and allowedto dry naturally. The sensor is not suitable for sterilisation by steam or exposure to chemicals such as ethylene oxide or hydrogen peroxide.Calibration IntervalThese sensors are designed to have minimal drift over their useful lifetime. For maximum accuracy, however they should be calibrated before each use.If the Sensor is DroppedIf a sensor is dropped, then it should be placed in quarantine for 24 hours and a follow-up check made by a 2-point calibration.Mechanical InstallationWhen installing the sensor, it must only be screwed in hand-tight and a gas-tight seal ensured. Spanners and similar mechanical aids may not be used, as excessive force may damage the sensor thread.RFI/EMI SusceptibilityMediceLs contain metal and may be susceptible to RFI or EMI. They are not suitable for use in MRI environments. For further information, please contact Honeywell.

汽车氧传感器手册倍速智能氧传感器部门制作2015年8月目录INDEX一、什么是汽车氧传感器二、汽车氧传感器的作用三、汽车氧传感器的分类四、汽车氧传感器易出现的问题五、汽车氧传感器的维修保养六、汽车氧传感器的市场状况一、什么是汽车氧传感器汽车氧传感器也称气体浓度传感器,一般安装在排气歧管、前排气管内、后排气管上,是发动机电控系统中一个非常重要的的传感器,其功能是通过监测排气中氧离子的含量来获得混合气的空燃比信号,并将空燃比信号转变成电子信号输入发动机ECU。
ECU根据氧传感器信号对喷油时间进行修正,实现空燃比反馈控制(闭环控制),从而将空燃比控制在14.7左右(过量空气系数为0.98~1.02),使发动机得到最佳浓度的混合气,从而达到降低有害气体排放和节油的目的。
二、汽车氧传感器的作用汽车氧传感器对汽车电喷系统的正常工作起着非常重要的作用。
汽车电子控制燃油喷射发动机正常运转和尾气排放的有效控制起着至关重要的作用,一旦氧传感器及其连接线路出现故障,不但会使排放超标,还会使发动机工况恶化,导致怠速熄火、发动机运转失准等各种故障。
因此,适时地对氧传感器进行监测和观察,对保证汽车在良好状态下运行很重要。
三、汽车氧传感器的分类目前,汽车发动机燃油喷射系统采用的氧传感器分为氧化锆型传感器和氧化钛型传感器俩中。
氧化锆型传感器又分为加热型和非加热型,氧化钛型传感器一般都为加热型。
由于氧化锆型传感器价格便宜,且不易受到硅离子的腐蚀,因此大多汽车都采用氧化锆型传感器。
氧化锆和氧化钛等敏感材料在高温时与废气中的氧发生反应,输出微弱的电压信号。
随着废气中含氧量的不同,产生和输出的电压值不同,从而对废气中氧的含量进行监测。
以氧化锆式传感器为例,传感器内侧通大气,外侧暴露在排气管中,高温时(400℃以上),若氧化锆内表面处气体中所含氧的浓度,与外表面处气体所含氧的浓度有很大差别,氧化锆元件内、外侧两极间就产生一个电压。
当混合气浓度较稀时,排气中氧的含量较高,传感器元件内、外侧浓度差别很小,氧化锆传感器产生的电压低(接近0伏);反之,混合气过浓,在排气中几乎没有氧,传感器内、外两侧氧的浓度相差很大,氧化锆元件就产生高电压(约1.0伏)。
