Field of application
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.
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.
Benefits
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
