This unit is suitable for controlling the maximum and minimum levels in silos and tanks containing materials such as powder, granule, such as rice, cereals, plastic material, coffee,sand, etc.
Its functioning is due to the pressure created by a product on the rubber membrane which activates a fast acting microswitch. The sensitivity of the switching can be adjusted by means of a screw placed on the lid of the unit, adjustment is made depending on the material to be sensed as a function of its specific weight. Variations in humidity and temperature do not compromise the functioning, furthermore the membrane is resistant to blows and vibrations.
