Murphy oil pressure gauge from the A20P Series Swichgage instruments. This range of mechanical gauges has a diaphragm-actuated gauge and features a classic look featuring a stainless steel bezel, black dial and white graphics. The gauge is protected with a polycarbonate case and also features a tough polycarbonate lens.

Pressure changes at the diaphragm are converted to mechanical movements to operate the oil pressure gauge. The pressure port features a pulsation dampener to help eliminate excess movement in the pointer to permit highly accurate readings. This gauge is said to be accurate within 2% in the middle 1/2 of the scale, and within 3% in the lower and upper 1/4.

The Murphy A20P series oil pressure gauges are suitable for monitoring transmission oil and crankcase oil, as well as for industrial and automotive applications.

The Murphy Swichgage has a built in electrical switch which can be used for triggering alarms or shut down devices. In the A20P model the pressure indicating needle acts as one switch pole which completes the circuit when it touches the level set by the adjustable contact.

This oil pressure gauge is the Murphy A20P-0-100, which measures from 0-100 PSI.
