Mechanical Pressure Switches from KOBOLD are suited for measuring, monitoring and analysis of overpressure, vacuum pressure and differential pressure. Constructed mainly form high quality stainless steel (1.4571) and copper alloy, all these pressure sensors are equipped with measuring bellows, which are subject to low loads and move on slightly. So it ensures a low switching point drift and high overpressure safety resulting in a long service life. An international stop can be used to restrict the movement of the measuring bellows such that the transmission of forces due to overpressure to the switching mechanism is stopped. The sensor has no seals as its parts that are in contact with the medium is welded together. Low pressure ranges Cu bellows are soldered to the sensor housing.
