Technical data .book Page 26 Tuesday, March 12, 2013 11:33 AM 7 TECHNICAL DATA LS 6500 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.
