The model RLT-2000 level sensor has been developed for measuring the level of liquids.

Measuring principle
A permanent magnet built into the float triggers, with its magnetic field, the resistance measuring chain built into the guide tube. The entire assembly corresponds to a 3-wire potentiometer circuit. The measured resistance signal is proportional to the level. The model RLT-2000 is optionally available with a 4 ... 20 mA output signal.
