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
