The Murphy 0-30 PSI Mechanical Pressure Swichgage with 2-Inch/51mm Dial A20P-30 is a diaphragm-actuated pressure-indicating gage with built-in electrical switch for tripping alarms and/or shutdown devices. This rugged, built-to-last instrument is face sealed from the environment by the unique combination of a polycarbonate case and lens, a polished stainless steel bezel and O-ring seals.

Accuracy and protection from moderate overpressure is assured by a unique, unitized diaphragm chamber. A built-in pulsation dampener helps eliminate pointer flutter and is removable for cleaning. The gage pointer acts as a pressure indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contacts have self-cleaning motion to ensure electrical continuity.

Applications includes: engines/equipment in Oil Field, Marine, Irrigation, Construction and Trucking Engines for Lube Oil Pressure, Water Pump Pressure, Hydraulic Pressure and Air Pressure.
