For Further Information

More informations

The conductive level switches of the model series FK12 are suitable to detect the level of conductible liquids along with the electrode relay FKE.

An alternating current is connected to an electrode insulated of the vessels casing. If this electrode is wetted a small current flows from the electrode to the casing of the vessel (in the case of plastic vessels, a separate common ground electrode is used).

This current is detected by the electrode relay and output as a switching signal.

Typical applications

For level detection in tanks
with conductive liquids
Full- and empty-signal
Level control between two levels
Overflow protection
Dry run protection

Advantages

No moving parts
Independent from the specific weight of the medium
