Application

Measurement in pure and ultrapure water:

  • Monitoring ion exchangers
  • Reverse osmosis

The measuring range of the sensors depends on the cell constant k:

  • k = 0.01 cm –1 : 0.04 to 20 μS/cm
  • k = 0.1 cm –1 : 0.1 to 200 μS/cm

Sensors with a Pt 100 temperature sensor are used together with conductivity transmitters equipped with automatic temperature compensation:

  • Liquiline M CM42
  • Liquisys M CLM223/253

For measurement of specific resistance, MΩ · cm measuring ranges are available in the menus of these transmitters.

Your benefits
  • Installation in pipes or flow chambers
  • Pt 100 temperature sensor for temperature compensation
  • Compact design
  • Very good price
Measuring principle

The conductivity of liquids is measured with the following measurement setup: Two electrodes are immersed in the medium. An AC voltage is applied to these electrodes which generates a current in the medium.

The electric resistance or its reciprocal value, the conductance G, is calculated according to Ohm’s law. The specific conductivity κ is determined using the cell constant k that is dependent on the sensor geometry.
