The unit also pro-vides simultaneous readings of the measured value (conductivity, con-centration or salinity) and tempera-ture, clearly portrayed in a well-arranged LC display, with analog outputs for both. Status annunciators indicate the mode of operation. The AC/DC universal power capability allows the transmitter to be con-nected to almost any power source.Process safety - in the foreground.SensoCheck ®continuously monitors the sender coil and wiring for short circuits, and the receiver coil for any disruptions. GainCheck ®allows a manual functional check of the transmitter at any time. In addition,an installed background program carries out an independent, periodic check of all instrument functions. A red LED in the front panel optically signals any alarm condition. A 22mA alarm signal can be set in the event of a malfunction.Rapid connection and start-up.Plug-in terminals and front panel access allow rapid installation of sensors and output wiring. Instru-ment mounting configurationsinclude wall, pipe or panel mounting.The robust plastic enclosure can withstand the harshest process conditions with a rating of IP65,NEMA 4X.Simple calibration.Calibration of the transmitter and sensor is carried out either through direct entry of the factory calibrated cell factor orthrough manual validation of the cellfactor using a standard calibration solution. Temperature may also be calibrated to provide more precise automatic temperature compensation of the measured conductivity values.Variety of process adaptions.The sensors can be inserted into a process pipe by means of athreaded bushing or Tri-Clamp fitting.PID proportional, integral, deriva-tive control.Built-in control enables complete loop autonomy where desired. Control output is through relays based on pulse frequency for metering pumps or pulse duration for solenoid valves. Analog outputs are still available for conductivity and temperature.ApplicationsSemiconductor processescan be monitored with sensors of glass-filled PEEK and no wetted metal parts. Process purity require-ments are protected.Waste water monitoring reliability is assured with non-fouling inductive sensors even at high conductivity and suspended solids levels.Inductive sensors measure even in concentrated, zero-dis-charge applications.Deionization Regeneration acid and base concentrations can be controlled reliably and accurately with inductive conductivity measure-ment. Direct temperature-compen-sated, % by weight readout isprovided for all chemicals used for deionizer and softener regeneration.Pharmaceutical Clean-in-Place (CIP) processes requiring control of chemical concentrations can use inductive conductivity measurement.It can also be used to validate con-centrations at the return end of the line and for waste treatment.7100E Inductive Conductivity SystemDimensions: inches (mm).3Conductivity Input Mettler-Toledo Thornton 7250 Series inductive sensors Conductivity Ranges0.000 to 9.999 mS/cm –00.00 to 99.99 mS/cm 0.000 to 9.999 S/m 000.0 to 999.9 mS/cm 00.00 to 99.99 S/m0000 to 1,999 mS/cm–Concentration Ranges NaCI 0 to 26%(0 to 60 °C)HCI 0 to 18%(-20 to 50 °C)NaOH 0 to 14%(0 to 100 °C)H 2SO 40 to 30%(-17 to 110 °C)HNO 30 to 30%(-20 to 50 °C)H 2SO 432 to 84%(-17 to 115 °C)H 2SO 492 to 99%(-17 to 115 °C)HCI 22 to 39%(-20 to 50 °C)HNO 335 to 96%(-17 to 115 °C)NaOH18 to 50%(0 to 100 °C)Salinity Range 0.0 to 45.0% (0 to 35 °C)Measurement Error < 1% of measured value + 0.005 mS/cm Temperature Input*Pt100 / Pt1000 / NTC 100 k ΩMeasuring Range Pt: -20 to +200 °C / -4 to +392 °F NTC: -20 to +130 °C / -4 to +266 °F Resolution 0.1 °C / 1 °FMeasurement Error 0.5 K; ±1K with Pt100Temperature Compensation Linear: 00.00 to 19.99 %/K (Reference temp. 25 °C)Non-Linear: natural water to EN 27888 (0 to 35 °C)Display 3-1/2 digit liquid crystal display with alarm LEDCurrent Outputs Two, 0 to 20 mA or 4 to 20 mA, max. 10 V, isolated, 22 mA for error message, can be disabled; dedicated to conductivity and temperature Current Characteristics Linear or logarithmicCurrent Error < 0.3 % of current value ± 0.05 mAStart/End ScaleSelectable within the measurement range for mS, S, % by wt, salinity, temperatureMinimum Measurement SpanLinear: 5% of selected measurement range Logarithmic: 1 decade47100E S y s t e m7100E Inductive Conductivity Transmitter Specifications7100E Inductive Conductivity TransmitterSpecificationsCell Factor Range00.100 to 19.999Monitoring of Cell Sensocheck®: monitoring of sender coil and leads for short circuits, and ofthe receiver coil for disruption (can be disabled).Relays* 4 SPST relay switching contacts, isolatedRelays 1 & 2 for limits, with adjustable NO/NC, hysteresis and delayOptionally, relays 1 & 2 for PID controlRelay 3 for system alarmRelay 4 for sensor washRelay Ratings AC: < 250 V, < 3 A, < 750 VADC: < 30 V, < 3 A, < 90 WPID Process Controller*Output via relay contactsProportional Action Controller Gain K C: 0010...9999%Integral Action Reset Time T R: 0000...9999 SDerivative Action Reset Time T D: 0000...9999 SController Type Pulse length or pulse frequency controllerPulse Period0001...0600 S, minimum ON time 0.5 S (pulse length controller)Maximum Pulse Frequency0001...0180 pulses/minute (pulse frequency controller)Power Supply20 to 253 VAC/DC, AC: 45 to 65 Hz, approx. 5 VA , 2.5 WOvervoltage category II; Protection class IIAmbient Conditions Operating/ambient temperature -20 to +55 °C;Transport and storage temperature -20 to +70 °CRelative humidity 10 to 95% non-condensingEnclosure Polymer case, PBTP (polybutyleneterephthalate)Installation Wall-mounting hardware, standardPipe/bracket for 1-1/4 to 2” pipe, φ40 to 60 mm, with kit ordered separatelyControl panel, cutout to DIN 43700, with kit ordered separatelyDimensions144 x 144 x 105 mm (5.67 x 5.67 x 4.13 in.)Protection IP 65, NEMA 4XCable Entry 5 ports for cable glands M20 x 1.5 or 1/2” conduitWeight Approx. 1 kg (0.5 lb.)FM/CSA NI, Class I, Div 2, Group A, B, C, D; T4EMC EN 61326EN 61326/A1EN 61000-4-5, Installation Class 2* ConfigurableDescription Part No.Inductive Conductivity Transmitter with Wall Mounting Hardware7100EPanel Mounting Kit for 7100E52 120 740Pipe Mounting Kit for 7100E (1-1/4” to 2” Pipe)52 120 741567100E S y s t e m⏹Chemically resistant PEEK (polyetheretherketone) or PFA (perfluoro alkoxy)⏹No metal wetted parts⏹High-Temperature to 180 °C (356 °F)⏹Wide measuring range to 2,000 mS/cm ⏹Unaffected by severe fouling⏹Simple installation of sensors and accessories ⏹Variety of process insertion fittings⏹Submersion installation for wastewater treatment ⏹Robust sensor design for maintenance-free operation⏹Integrated temperature probe for direct temperature compensationFeaturesOperationThe inductive conductivity sensor consists of two high-grade toroids (coils) which are incorporated concentrically and adjacent to one another in a polymer body. These coils form a current transformer.The sensor is designed so part of the liquid media forms a closed con-ductive current path passing through the toroids. The primary coil is acti-vated with a sinusoidal alternating voltage, which induces an alternating voltage in the liquid loop (sample medium). In liquids which conduct electricity, this causes a current flow which is proportional to the conduc-tivity of the sample medium.The liquid loop is also acting as the primary winding of the secondary coil which functions as a current transformer. This current is rectified to the correct phase and amplified. If the toroid of the sensor is mounted in a relatively small (< 3”) pipe, the field around the toroid, and therefore the effective cell factor, will be influenced. In that case, calibration in thepipe is needed to achieve rated accuracy.* PFA versionDimensions: mm (inches).7250 Inductive Conductivity SensorsDescriptionA B C Part No.Threaded bushing 2” NPT PVDF 2” NPT SW7524 (0.95”)52 403 453Sanitary Fitting 2” Tri-Clamp SS–––58 084 013PeekPFA0 to 2,000 mS/cm 0 to 2,000 mS/cm 2.17 2.301201202”NPT bushing or Tri-Clamp fitting (see table below)2”NPT bushing or Tri-Clamp fitting (see table below)0.9 kg (2 lb.)0.9 kg (2 lb.)Pt 1000Pt 1000Approx 5 minutes (90%)Approx 5 minutes (90%)Glass filled PEEK (GF30)Unfilled PFA1.4435 (316) Stainless Steel 1.4435 (316) Stainless Steel Viton / Viton FEP/PTFE 5, 10 m (16, 33 ft)5,10 m (16, 33 ft)7-20 to 100 °C (-4 to 212 °F)-20 to 180 °C (-4 to 356 °F)7250 Series SensorsMeasuring Range Cell Factor Transfer Ratio Installation WeightTemperature Sensor Temperature Response Wetted Material Mounting Thread O-ring / Gasket Cable LengthsTemperature Part No.52 002 7375 m (16 ft)10 m (33 ft)52 002 738Max Pressure Measurement Value Deviation Cable Jacket MaterialCable Length m (ft)PVC 8 bar (116 psig)±(0.5% of measurement + 25 µS/cm)52 002 7405 m (16 ft)10 m (33 ft)52 002 741Silicone 20 bar (290 psig)±(0.5% of measurement + 1 µS/cm)A combination of high pressure, high temperature and/or aggressive process medium can reduce sensor life.7250 Series Insertion Adapters7250 Series Adapter Dimensions7250 Inductive Conductivity Sensors & Accessories-20 to 125 °C (-4 to 257 °F)16 bar (232 psig)±(0.5% of measurement + 25 µS/cm)Silicone52 005 4245 m (16 ft)10 m (33 ft)52 005 425Mettler-Toledo Thornton, Inc.36 Middlesex Turnpike Bedford, MA 01730 USA Tel. +1-781-301-8600Fax +1-781-301-8701Toll Free +1-800-510-PURE ******************** Subject to technical changes © Mettler-Toledo Thornton, Inc.

环形电导率传感器⋅非接触（环形）电导率传感器－抗腐蚀，防堵；⋅可用于浓度测量－酸液、碱液和含盐溶液的浓度测量；⋅多种安装方式可供选择－沉浸式、插入式和流通式；⋅与分析仪器的适配性－可以与Rosemount Analytical的所有环形电导率分析仪器配套使用；⋅卫生型传感器225－满足3A卫生标准。

性能和应用Rosemount Analytical的环形电导率传感器适合于腐蚀性强和容易产生堵塞的溶液测量。

环形（电感应）电导率传感器的测量原理采用一对线绕金属环形线圈，传感器的电极与过程是完全隔离的。

两个线圈，一个作为发送器，另一个作为接收器。

当给发送器线圈通电时，则电解质溶液导电产生感应电流，该感应电流与溶液的电导率成正比，接收器线圈检测该电流的大小，从而求出溶液的电导率值。

225、226和228环形电导率传感器是将两个线绕金属环形线圈定制在具有防腐性能的PEEK或Tefzel环形模具中。

222环形电导率传感器的结构则稍有不同，其也有发送器和接收器两个线圈，但这两个线圈是装在内衬聚四氟乙烯的短管内，工艺介质从短管中流过。

由于环形线圈不是直接插入被测溶液中，因此，要求用外部接线把电路接通。

所谓外部接线就是用短接片连接两个金属环。

金属环即是环形电导率传感器的两个工作线圈，同时也与工艺介质接触，短接片起连通线圈的作用。

对于222传感器，接触线圈就是传感器与工艺过程管线连接的法兰。

环形电导率传感器适用于高电导率检测，最高可以测量0-2S/cm（0-2,000,000µS/cm），而最低检测值则取决于传感器圆环的大小和环上缠绕的线圈数，最低检测值范围为50至500µS/cm。

环形电导率传感器的测量值与溶液的流速和流向无关，但一定要保证传感器的环形孔不能堵。

200系列环形电导率传感器可以与Rosemount Analytical的所有环形电导率分析仪器配套使用。

所有传感器均内置测温热电阻，其对电导率的检测值进行温度补偿。
