电导率仪的原理及其使用介绍
电导率仪的原理及其使用介绍电导率仪主要是测液体介质之间传递电流能力的仪器，一般用于电力、化工、冶金、环保、制药、野外、湖泊、科研、食品和自来水等溶液中电导率值（TDS）的连续监测，同时在水处理，水产养殖试验方面也有应用。
电导率仪的工作原理：电导率是物体传导电流的能力，电导率测量仪的测量原理是将两块平行的极板；放到被测溶液中，在极板的两端加上一定的电势(通常为正弦波电压)，然后测量极板间流过的电流。
根据欧姆定律，电导率(G)--电阻(R)的倒数，由导体本身决定的。
电导率的基本单位是西门子(S)。
因为电导池的几何形状影响电导率值，标准的测量中用单位电导率S/m（常用的还有μS/cm）来表示，以补偿各种电极尺寸造成的差别。
单位电导率(C)简单的说是所测电导率(G)与电导池常数(L/A)的乘积.这里的L为两块极板之间的液柱长度，A为极板的面积。
水的电导率与其所含无机酸、碱、盐的量有一定关系。
当它们的浓度较低时，电导率随浓度的增大而增加，因此，该指标常用于推测水中离子的总浓度或含盐量。
电导率仪使用时的注意事项：1、在测量纯水或超纯水时，为了避免测量值的漂移现象，建议采用密封槽；在密封状态下的进行流动测量，如采用烧杯取样测量，则会产生较大的误差。
2、因温度补偿是采用固定的温度系数，所以，超、高纯水的测量，尽量采用温度不补偿方式进行，测量后查表。
3、电极插头座应防止受潮，仪表应安置于干燥环境，避免因为水滴溅射或受潮，引起仪表的漏电或测量误差。
4、测量电极是精密部件，不可以分解，不可以改变电极形状和尺寸，且不可以用强酸、碱清洗，以免改变电极常数，而影响仪表测量的准确性。
5、为确保测量的精度，电极使用前，应用蒸馏水(或去离子水)冲洗二次(铂黑电极干放一段时间后，在使用前，必须在蒸馏水中浸泡)，然后用被测试样水冲洗三次后，方可测量。

介质流应流过传感器开孔 ( 参考传感器本体上的箭头标识 )。 对称性结构的测量通道允许双向介质流 通过。 在狭小空间中安装时，介质中的离子流受管壁 的影响。通过安装系数可以对此进行补偿。可 以在变送器中输入安装系数，或通过乘以安装 系数，对电极常数进行修正。 安装系数取决于管径、管道的导电性，以及传 感器与管壁间的距离。 传感器与管壁间的距离足够大时 (DN 65 时， a > 15 mm)，无需考虑安装系数 (f = 1.00)。 传感器与管壁间的距离较小时，电绝缘管道的 安装系数将增大 (f > 1)，导电性管道的安装系数 将减小 (f < 1)。 使用标定液可以测量安装系数，或基于以下曲 线图预估安装系数。

TI193C/07/en/09.0551500279Technical InformationLiquisys M CLM223/253Conductivity/Resistivity MeasurementTransmitter for conductive and inductive sensorsApplicationThe modular design of the Liquisys M CLM223/253 allows easy adaption of the transmitter to a variety of customerrequirements. Starting with the basic version for "measurement and alarm generation", the transmitter can be equipped with additional software and hardware modules for specialapplications. These modules can also be retrofitted as required.Application•Ultrapure water •Water treatment•Ion exchanger, reverse osmosis •Cooling water desalinisationYour benefits•Field or panel-mounted housing •Universal application •Simple handling–Logically arranged menu structure –Ultrasimple two-point calibration •Safe operation–Overvoltage (lightning) protection–Direct access for manual contact control –User-defined alarm configurationThe basic unit can be extended with:•2 or 4 additional contacts for use as:–Limit contacts (also for temperature)–P(ID) controller–Timer for simple rinse processes–Complete cleaning with Chemoclean •Plus package:–User defined current output characteristics–Automatic cleaning trigger on alarm or limit violation –Ultrapure water monitoring acc. to USP (United States Pharmacopeia) and EP (European Pharmacopoeia) (conductive)–Polarisation detection (conductive)–Concentration measurement–Temperature compensation via table–Process Check System (PCS): live check of the sensor –Adaptive calibration with installation factor (inductive)•HART ® or PROFIBUS-PA/-DP•2nd current output for temperature, main measured value or actuating variable•Current input for flow rate monitoring with controller shut offor for feedforward controlLiquisys M CLM223/253Function and system designFeatures of the basic version Conductive or inductiveTwo instrument versions for measurement with conductive (two electrode) sensors or inductive sensors areavailable. The use of inductive sensors that are less sensitive to soiling than conductive sensors is recommendedfor high conductivity measurement, concentration measurement or adhering media.Measuring of conductivity and resistivity (conductive)This is selected via the menu. During measurement, the value measured can be displayed in the othermeasuring mode. The temperature is displayed at the same time or, if desired, not shown at all.Temperature compensationThe following temperature compensation selections are available:•Linear•NaCl curve according to IEC 746•Ultrapure water NaCl (neutral compensation)•Ultrapure water HCl (acid compensation, also ammonia)The reference temperature is user defined, the standard value is 25 °C (77 °F).ConfigurationDifferent alarms are required depending on application and operator. Therefore the transmitter permitsindependent configuration of the alarm contact and error current for each individual error. Unnecessaryor undesirable alarms can be suppressed in this manner. Up to four contacts can be used as limit contacts(also for temperature), to implement a P(ID) controller or for cleaning functions.Direct manual operation of the contacts (bypassing the menu) provides quick access to limit, control orcleaning contacts, permitting speedy correction of deviations.The serial numbers of the instrument and modules and the order code can be called up on the display.The cell constant can be edited and even calibrated for demanding special applications.Additional functions of the plus package Current output configurationIn order to output wide measuring ranges while still achieving a high resolution in specific ranges, the current output can be configured as required via a table. This permits bilinear or quasi-logarithmic curves, etc. Polarisation detectionPolarisation effects in the boundary layer between the sensor and the medium to be measured limit the measuring range of conductive conductivity sensors.The transmitter can detect polarisation effects using an innovative, intelligent signal evaluation process. Process Check System (PCS)This function checks the measuring signal for stagnation. If the measuring signal does not change for some time (several measured values), an alarm is triggered. Soiling, blockage or similar could be the cause of such behaviour.Ultrapure water monitoring acc. to USP (United States Pharmacopeia) and EP (European Pharmacopoeia)Ultrapure water monitoring according to USP <645> and EP means that the uncompensated conductivity and the temperature are measured and compared to a table.The transmitter (conductive with additional contacts) comes with the following functions:•Monitoring of "Water for Injection" (WFI) according to USP and EP•Monitoring of "Highliy Purified Water" (HPW) according to EP•Monitoring of "Purified Water" (PW) according to EPThe user-adjustable pre-alarm indicates undesirable operating values in due time. Full compliance with USP or EP requires the use of a precisely calibrated sensor, for example, the CLS16.Liquisys M CLM223/253Concentration measuringThe conversion from conductivity to concentration is effected using four user-definable concentration curves . This permits concentrations to be displayed in %, ppm, mg/l or TDS (total dissolved solids).Adaptive calibration for determination of the installation factor (inductive)Inductive measuring sensors must normally be installed in pipes at a required minimum distance from the pipe wall. If this minimum distance is not observed, the measured value changes. The built-in adaptive calibration using the installation factor allows you to compensate for this once the sensor is installed.Second current outputThe second current output can be configured for temperature, main measured value (conductivity, resistivity, concentration) or actuating variable.Current inputThe current input of the transmitter allows two different applications: controller shut-down in case of lower flow rate violation or total failure in the main flow as well as feedforward control. Both functions are also combinable.Explosion proof versions for zone 2Remarks:•Permissible sensors: all conductive conductivity sensors, inductive sensors CLS50 (Non-Ex version) and CLS52.•Do not use blue sensor cables. Electric circuits are not intrinsically safe according to EN 50039.Application of transmitter and sensor in hazardous area zone 2Field housing CLM253 with power supply 24 VApplication of transmitter as relatedelectrical equipment in non-hazardous area or in simple pressurised apparatus; application of sensor in hazardous area zone 2Field housing CLM253 with power supply 230 V orPanel mounted housing CLM223 with power supply 230V or 24 VLiquisys M CLM223/253Measuring systemA complete measuring systems comprises:•The transmitter Liquisys M CLM223 or CLM253•A sensor with or without an integrated temperature sensor•A measuring cable CYK71 (conductive), CPK9 for Condumax H CLS16 or CLK5 (inductive)Options: extension cable, junction box VBMComplete measuring system Liquisys M CLM223/2531234Conductive sensor CLS15Liquisys M CLM253Liquisys M CLM223Inductive sensor CLS52567Inductive sensor CLS50Conductive sensor CLS21Immersion assembly CLA111Liquisys M CLM223/253InputMeasured variables Conductivity, resistivity, temperature Measuring rangeCable specificationCell constantTemperature sensors Pt 100, Pt 1000, NTC 30KMeasuring frequencyBinary inputsCurrent input4...20mA, galvanically separated Load: 260Ω at 20mA (voltage drop5.2V)OutputCurrent range 0/4 ... 20 mA, galvanically separated, active Error current 2.4 or 22 mA in case of an error Loadmaximum 500 Ω Linearisation transmission behaviourResolutionmax. 700 digits/mAConductivity (conductive):0 ... 60 mS/cm (uncompensated)Conductivity (inductive):0 ... 2000 mS/cm (uncompensated)Resistivity:0 ... 200 M Ω⋅cmConcentration:0 ... 9999 (%, ppm, mg/l, TDS)Temperature:-35 ... +250 °C (-31 ... +482 °F)Cable length (conductive):conductivity: max. 100 m (328.1 ft) (CYK71)resistivity: max 15 m (49.22 ft) (CYK71)Cable length (inductive):max 55 m (180.46 ft) (CLK5)Cable resistance CYK71:165 Ω/km (conductivity measurement)Adjustable cell constant:k = 0.0025 ... 99.99 cm -1Conductivity, resistivity (conductive):170 Hz ... 2 kHz Conductivity (inductive): 2 kHz Voltage:10...50V Power consumption:max. 10mAConductivity:Resistivity:Concentration:Actuating variable:Temperature:adjustable adjustable adjustable adjustableadjustableLiquisys M CLM223/253Min. distance for 0/4...20mA signalIsolation voltage max. 350 V RMS /500 V DC Overvoltage protection according to EN 61000-4-5Auxiliary voltage outputContact outputsLimit contactorControllerAlarmConductivity:Measured value 0 ... 1.999 µS/cm 0.2 µS/cm Measured value 0 ... 19.99 µS/cm 2 µS/cm Measured value 20 ... 199.9 µS/cm 20 µS/cm Measured value 200 ... 1999 µS/cm 200 µS/cm Measured value 2 ... 19.99 mS/cm 2 mS/cm Measured value 20 ... 2000 mS/cm 20 mS/cmResistivityMeasured value 0 ... 199.9 k Ω⋅cm 20 k Ω⋅cm Measured value 200 ... 1999 k Ω⋅cm 200 k Ω⋅cm Measured value 2 ... 19.99 M Ω⋅cm 2.0 M Ω⋅cm Measured value 20 ... 200 M Ω⋅cm 20 M Ω⋅cmConcentration no minimum distance Temperature15 °COutput voltage:15V ± 0.6Output current:max. 10mASwitching current with ohmic load (cos ϕ= 1):max. 2A Switching current with inductive load (cos ϕ = 0.4):max. 2ASwitching voltage:max. 250V AC, 30V DC Switching power with ohmic load (cos ϕ = 1):max. 500 VA AC, 60W DC Switching power with inductive load (cos ϕ = 0.4):max. 500VA AC, 60W DC Pickup/dropout delay:0...2000sFunction (adjustable):pulse length/pulse frequency controller Controller response:PIDControl gain K p :0.01...20.00Integral action time T n :0.0...999.9min Derivative action time T v :0.0...999.9min Period for pulse length controller:0.5...999.9 s Frequency for pulse frequency controller:60...180 min -1Basic load:0...40% of max. set valueFunction (selectable):Latching/momentary contactAlarm threshold adjustment range:Conductivity, resistivity, concentration,temperature, USP, EP: complete measuring range Alarm delay:0 (2000)s (min)Liquisys M CLM223/253Power supplyElectrical connectionThe instrument has protection class II and is generally operated without protective earth connection.
