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.
Approximate measures are given in mm.
