What is a pressure switch sensor?
A Pressure switch is a two-part device consisting of a sensing transducer and an electrical switch. The electrical switch opens and closes at a specific pressure often referred to as the Setpoint. Depending on the switch and the vendor, the switching pressure setpoint may be fixed or adjustable
