Pressure switch model

Pressure switches are used to monitor pressure in pneumatic systems by providing an output when a set pressure is reached, as well as improving operation and safety. For example, an air pressure switch is used to maintain a constant pressure,  and can turn the compressor off once the tank reaches the required air pressure level.  If the air pressure drops and more is required, the switch can also turn the compressor on.

According to the functions, they can be divided into mechanical pressure switches or electronic pressure switches.
According to application, there have differential pressure switches, explosion-proof pressure switches, air compressor pressure switch, well pump pressure switch, oil pressure switch etc.
