Technical data
7.1 Measuring principle
A high frequency signal sweep is radiated from the sensor tip into the tank / pipe. The medium
will act as a virtual capacitor, which together with a coil in the sensor head, will form a circuit
creating the switching point signal. This virtual capacity will depend of the dielectric value of the
medium and it is well defined for most media.
The measurement is precise and unaffected by the mounting position.
