Electronet series LCS-02 are conductivity-type level switches used for level measurement of conductive liquids.
The probe works on the principle of variation in electrical resistance between the reference electrode and the level control electrode.

When the medium covers the electrodes, the change in resistance is detected as a level signal.

• If the tank wall is electrically conductive, it can serve as the reference electrode.

• For tanks made of plastic, concrete, or other non-conductive materials, an additional reference electrode is required.
