Diaphragm Switches

Diaphragm Switches

Level control with a membrane is the most economical method in measurement  of  level of  bulk  material  in  the  storage.  It  can  be used in open and non-pressure tanks. The diaphragm switch can check full, empty and loaded situations of powdered, dusty, corny, granular, grained bulk materials in the grain elevator. It is appropriate for using particles with 0,3 and 2,5 t/m³ and up to max. 30 mm.  The Membrane must be in contact with the material.

Working Principle:
As  long  as  material,  which  is  poured  to  the  grain  elevator, accumulates, the  membrane  is  closed.  The material  pushes  membrane back with composed press and mechanism pushes the contact. Contact  gives  audible  alarm  or sends a signal to stop the  filling mechanism of the grain  elevator.  When the material  precipitates and reduces, the contact reverts back. Precision setting is made during assembly by sliding the mechanism.
