Condumax CLS21D measures conductivity in all process and environmental applications, such as:

  • Potable water treatment

  • Desalination plants

  • Industrial water treatment

  • River/lake monitoring

  • Phase separation in medium conductivities (e.g. milk/water)

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

Benefits

  • Reliable and accurate measuring values at medium to high conductivities

  • Robust design for long durability and low maintenance

  • High chemical, thermal and mechanical stability

  • Quality certificate stating the individual cell constant

  • Logging of sensor-specific data for easy traceability and predictive maintenance

  • Maximum process safety via non-contact inductive signal transmission

Videos

  • 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.

  • Memosens converts the measured value to a digital signal and transfers it to the transmitter without a contacting connection. This video shows how Memosens optimizes process control and maintenance.
