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.
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.
