• The Memosens inductive sensor-cable connection system is suitable for use in hazardous
areas, Zone 2. The corresponding EU declaration of conformity is part of this document.
• The certified conductivity sensors CLS15D / CLS16D / CLS21D may only be connected via
the measuring cable CYK10-V*** to the certified intrinsically safe digital sensor output
circuits of measuring device Liquiline M CM42-KV*********.
• The electrical connection must be made according to the wiring diagram of the transmitter.
• Metallic process connection parts must be mounted at the mounting location
electrostatically conductive (< 1 MΩ).
• The CLS15D-type sensors with non-metal process connections and the CLS21D-type
sensors may only be employed for measurement in liquids with a minimum conductivity of
10 nS/cm.
• The CLS15D-type sensors with non-metal process connections may not be operated under
process conditions in which electrostatic charging of the sensor, particularly of the
electrically insulated outer electrode, is likely to occur.
• The maximum permitted cable length is 100 m.
• Full compliance with regulations for electrical systems in hazardous areas (EN/IEC
60079-14) is mandatory when using the devices and sensors.
