Application

Measurement in media with average or high conductivity:

  • Separation of media with average conductivity (milk/water)
  • Separation of media with high conductivity (alkali/water)
  • Drinking water treatment
  • Wastewater treatment

Sensors with temperature probes are used in conjunction with conductivity measuring devices that support automatic temperature compensation:

  • Liquiline CM442/CM444/CM448 (only CLS21D)
  • Liquiline CM42
  • Liquiline CM14 (only CLS21D)
  • Liquisys CLM223/253 (only CLS21)

The resistivity in MΩ cm can also be measured using these transmitters.

Your benefits
  • Different designs for optimum adaptation to the process or mounting location
  • Installation in pipe or flow assembly
  • Compact design
  • With plug-in head (IP68 (CLS21D), IP65 (CLS21)) or fixed cable (IP67)
  • High chemical, thermal and mechanical resistance
  • Manufacturer inspection certificate stating the individual cell constant
Other advantages of Memosens technology
  • Maximum process safety owing to non-contact, inductive signal transmission
  • Data security thanks to digital data transmission
  • Very easy to use as sensor data saved in the sensor
  • Recording of sensor load data in the sensor enables predictive maintenance
Measuring principle

Conductivity of liquids is determined with a measuring arrangement where two electrodes are located in the medium. An alternating voltage that causes a current to flow through the medium is applied at these electrodes. The electrical resistance, or its reciprocal value - conductance G - is calculated based on Ohm's law. The specific conductance κ is determined from the conductance value using the cell constant k, which depends on the sensor geometry.

Measuring system

A complete measuring system comprises the following components at least:

  • The conductively measuring conductivity sensor CLS21D or CLS21
  • A transmitter, e.g. Liquiline M CM42
  • A measuring cable, e.g. Memosens data cable CYK10 or CYK71 for analog sensors
