Level control relay with resistive level probes

Controls the level of an electrically conductive liquid by starting and stopping a pump. To detect the level suitable metal probes are used. The probes are supplied with low AC voltage, isolated from the mains, so no electrolysis can occur and protection is provided.

There is a button to adjust the sensitivity of the device and another to adjust the start delay (t).

The relay can operate according to two distinct modes of level management:

• filling

• emptying
