Diaphragm Pressure Switch
Presair’s diaphragm pressure switch has an user adjustable set-point and small switching differential. Presair’s diaphragm operated pressure switches can operate at low pressures and reach up to 125 Psi.
Presair’s adjustable pressure switch contains a pressure sensitive diaphragm which operates a non latching snap action microswitch. The switch can be used to operate an electrical circuit when the system pressure rises or falls through an operator-determined pressure set point between 0.25 inches of water to 125 Psi.
