Presentation
Functions
These devices monitor the levels of conductive liquids.
They control the actuation of pumps or valves to regulate levels, and are also suitable for protecting submersible pumps
against running empty, or protecting tanks from “overflow”. They can also be used to control dosing of liquids in mixing
processes and to protect heating elements in the event of non immersion.
They have a transparent, hinged flap on their front face to prevent any accidental alternation of the settings. This flap can
be directly sealed.
