In conjunction with a pressure gauge apply correct operating pressure to switch. The oil pressure differential switch breaks the control circuit and shuts down the compressor when the pressure difference between the oil pump outlet and the crankcase is too low. Release pressure (switch is now set approximately) 4.

The first diagram shows the function of the differential switch during start; No maintenance is required on these differential pressure close the. The differential pressure, acting on the sensitive diaphragm.

The second shows the function of the switch during operation. A differential pressure switch is designed to sense a difference in pressure between two pressure sources in the plant for control purposes. A more precise setting can be achieved by repeating the above and will provide a rising pressure
