The SC42/SX42 series is designed to meet the challenges of high-pressure and high-temperature environments. These contact line sensors offer high accuracy and reliability for measuring conductivity in applications such as boiler blowdown and condensate leakage. The SC42/SX42 series is available in a variety of configurations to suit different installation needs, including threaded connections and flanged options for easy integration into existing systems.
Withstanding temperatures up to 250°C and pressures up to 40 bar (depending on model), the SC42/SX42 is optimised for demanding environments where accurate measurement results are essential. High-quality stainless steel materials ensure long life and corrosion resistance, even in aggressive process environments.
The sensor is designed to minimise common problems such as polarisation and contamination, ensuring long-term stability and reduced maintenance requirements. The integrated Pt1000 temperature sensor enables accurate temperature compensated measurements.
