A pressure switch, also called a pressure switch, allows you to set a switching pressure in advance. When the set pressure is reached, the pressure switch opens or closes a switching contact or sends out a control signal. Various versions are available, both mechanical and electrical.
In many processes, pressure monitoring is essential. A well-chosen pressure switch can help with this. A pressure switch is often found around pumps, compressors and production machines. Based on the output of such a switch, valves can be controlled and machines or alarms can be switched on or off. This functionality can also be controlled with a PLC and pressure sensor, but by combining this functionality in one device a simpler, cheaper and easier to maintain system can be realized in many situations.
