Most of the above pressure sensors of the mechanical pressure switches are equipped with the measuring bellows which are subjected to lower loads and show very slight movement in comparison with the permissible values.Made up of high quality stainless steel(1.4571) and copper alloy, it facilitates various benefits like long life in addition to lower switching point drift and excellent over-pressure safety.The parts of the sensor ,in contact with the medium, are welded together without additional materials and the sensors contain no seals.
To prevent the transmission of the forces which result in over pressure to the switching mechanism, an International stop is used in the equipment. Low pressure range used copper bellows are soldered to sensor housing.
