A high frequency signal sweep is radiated from the sensor tip into the tank or pipe. The medium acts as a virtual capacitor, which together with a coil in the sensor, will form a circuit creating the switching point. This virtual capacity will depend of the dielectric value of the medium and is well defined for most media.
