Diaphragm level switches are instruments designed to measure the level of bulk material in the tank and silo. It is economical. It can be used in open and unpressurised tanks. The full, empty and loaded status of dusty, powdered, granular, granular bulk materials in the silo can be controlled. 0.3 to 2.5 t / m3 and max. Suitable for particles up to 30 mm. The membrane must be in contact with the controlled material. As the material poured into the silo piles up, the membrane closes. With the pressure formed, the material pushes the diaphragm back and the mechanism pushes the contact. The contact is used to give an audible alarm or to stop the filling mechanism of the silo. When the material collapses and decreases, the contact returns to the old position. Sensitivity adjustment is made during assembly by sliding the mechanism. It is used in many materials such as Sugar, Hazelnut, Clay, Core, Coffee, Various Granules, Wheat, Bauxite, Ceramic, Legumes, Grain, Fish Feed, Sand, Gravel, Insulation Materials, Corn, Rice.
