Model: DPA22 type (MODEL TYPE: DPA22)
This differential pressure switch is assembled into a unique mechanism using two Bourdon tubes that receive two different pressures and one micro switch to sensitively detect the minute pressure difference between the two pressures, and is an excellent, high-performance switch with excellent vibration resistance that opens and closes one electrical circuit when the differential pressure reaches the desired preset value.
Differential pressure setting method
The differential pressure value can be easily set by turning the differential pressure setting knob and aligning the setting pointer with the upper limit scale value.
