Analog conductivity sensor
Condumax CLS12

Conductive conductivity sensor for high temperature applications in the power & energy industry

  • ©Endress+Hauser
  • The conductivity of a liquid can be measured using the conductive or toroidal measuring principles. This video shows what it is about and how these measuring principles work.

Condumax CLS12 is a robust conductivity sensor for steam/water cycles in power plants. It is optimized for low conductivities (even under high temperatures and pressures) to protect your processes from deposits and corrosion. Low maintenance and simple to commission (large connection compartment), this is the ideal sensor for tough environments.


  • Reliable and accurate measuring values at low conductivities

  • Optimized for high pressures and temperatures up to 160°C (320°F)

  • Easy cleaning thanks to stainless steel body and removable outer electrode

  • Robust design for high durability

  • Quality certificate stating the individual cell constant

Field of application

Condumax CLS12 measures conductivity in the steam/water cycle in the power & energy industry:

  • Condensate monitoring

  • Boiler feedwater monitoring

  • Boiler blowdown control

The sensor can be used in all low conductivity applications with high temperatures and pressures.

With its international explosion protection approvals, such as ATEX and FM, the sensor is suitable for hazardous area use.
