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.

  • Analog conductivity sensor Condumax CLS12

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

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.
