The current fl ow in the medium gen-erates another magnetic fi eld in the secondary coil (receiver). The strength of the induced current in the secondary coil depends on the conductivity of the medium.The conductivity of the liquid medium is temperature dependent. To compensate the temperature error, an additional sensor (NTC) in the sensor tip is used for moni-toring the temperature of the medium. The temperature coeffi cient (TC-value) of the liquid can be set up in the electronics of the ILM which is used for automatic compen-sation of the temperature error.AuthorizationsProduct Information ILM-2 | ILM-3ILM-2-L20-M12ILM-2-L50-M12 with AMC-351-DN50Inductive Conductivity Meter ILM74-06Induced current fl ow I~Sender ReceiverMediumNTCF O O D 2SpecificationComparison ILM-2 / ILM-3 ILM-2 ILM-3Measurement ranges conductivity0...2 mS/cm up to 0...999 mS/cm 12 measurement ranges selectable 3 ranges extern switchable0...0.5 mS/cm up to 0...999 mS/cm 14 measurement ranges selectable 4 ranges extern switchableMeasurement ranges temperature 0...+150 °C 1 measurement range fix presetted-20...+150 °C 7 measurment ranges selectableTemperature coefficient (TC) 0...5 %/K, free adjustable 1 TC for all measurement ranges0...5 %/K, free adjustable 1 TC for each measurement rangeSpecificationProcess connections thread G1" torquesensor, combined with Negele-weld-in sleeves max. 20 NmMaterials connector head thread connection bobbin case window in lidstainless steel 1.4305 (303), Ø 89 mm stainless steel 1.4305 (303), SW 36 mm PEEK, FDA-number (21CFR177.2415) PMMATemperature ranges ambient process CIP/SIP cleaning-10...+60 °C (14...140 °F) 0...100 °C (32...212 °F) up to 140 °C (284 °F)/30 minutes max.Pressure 10 bar max.

Installation in a rising pipe is recommended. · The inscription “FLOW” on the bottom side of the sensor has to show in-flow direction of the medium. · Very heavy vibrations can cause measurement errors (e. g. installation very close to a pump). · Use Negele CLEANadapt system for safe operation of measuring point · Attention: The maximum tightening torque for mounting is 20 Nm · Use a welding mandril for correct installation of CLEAN-adapt weld-in fittings. Please pay attention to the weld-in and installation details in the CLEANadapt product information.20 / 5060 / 90F O O D 4InstallationElectrical connectionWith M12 plugHandling/OperationAdjustment of measuring range · Delivery status: measurement range 1: 0...20 mS/cm = 4...20 mA TC-value: 2 %/K · Via the external control voltage +24 V DC (18...36 V) range 2 (E1=24 V), range 3 (E2=24 V) or range 4 (E1=E2=24 V) can be selected (see “Electrical Connection”). · At ILM-3 each measurement range can be assigned a sepa-rate temperature coefficient (TC). At ILM-2 one and the same TC is effective for all measurement ranges. · At ILM-2 the temperature output is fix presetted to 0...150 °C. · At ILM-3 the measurement range of the temperature output can be selected from 7 preset ranges between -20...150 °CE1 E2 Meas. range0 0 11 0 20 1 31 1 4*Detecting the temperature coefficient of the mediumDelivery status: see Handling/Operation 1.
