Filsa membrane level controller

FILSA Membrane level controllers are specifically built to control easy flowing bulk material under atmospheric pressure. They can be used to control level inside silos or to detect obstructions in conveying systems or on surfaces whose slope is not greater than 40°.

The membrane of the controller should be exposed to the material to be controlled. When the material entering the silo piles up and covers the membrane, the pressure exerted obliges the membrane to move backwards, actuating on the mechanism which drives the switch. This switch can be used to start or stop optical or acoustic signals or the loading and unloading mechanisms of the silo or container.
