Function:
The membrane must to be exposed to the material.
The movement of the switch is the result of the pressure exerted by the incoming bulk material against the membrane which forces the membrane to move backwards, reversing the position of the switch and the signal is used for example to control the transport system in the silo.
The models “A-100”, “AD”, “SR” y “CD2M” and the models with S.S. membrane have a regulation system by a spring that allows the adjustment of the sensitivity. Tightening the regulation nut to reduce the sensitivity and increase the strain of the material to activate the microswitch. Clockwise insensitive.
The models are adjusted at their maximum sensitivity. It is necessary to ensure the proper pressure to the membrane that returns the membrane when there is no product covering it.
Special sensitive membrane level indicator. Is to be used to control the maximum level of bulk solids in silos or vessels or control the flow and obstructions in tubes, pipes, conveyors, etc. With a high sensitivity, the indicator can detect false signals due to vibration or movements of the place where it is mounted.
These controllers consist of a switch actuated by a membrane and it is recommended for dusty and powdery, granulated and grainy bulk goods like dust, flour, grain, sand, plastic, etc. with an easy flow and a bulk density from 0.3 to 2.5 t/m3.
