The Murphy 0-300 PSI Mechanical Pressure Swichgage 2.5" with High and Low Contacts A25P-HL-300 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.
