Robust and reliable level monitoring for fluids and bulk materials in cylindrical design with thread. The sensors are suited for installation using mounting plates and nuts or adapters in the tank wall. 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. EGE filling level sensors in cylindrical design are designed for rough industrial environments with PTFE housing for use in aggressive media. Also available with robust stainless steel thread.
