Capacitive filling level monitors for operation at medium temperatures of up to 230° C. With PTFE or PEEK housing and stainless steel thread for use in aggressive media. The sensors are based on the proven capacitive principle. The medium to be detected functions as dielectric. The medium in touch with the sensor generates a capacity change. This is converted into a switching signal or an analogue 4...20 mA output signal. This applies both to conductive and on-conductive media. With their small design the sensors of this series are well suited for installation in tight spaces. Upon request we supply the sensors with FDA certificate.
