The Murphy 0-150 PSI Mechanical Pressure Swichgage Oil Sealed 2" with Internal Snap-Acting Switch A20PE-OS-150 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.
The A20PE-OS-150 features internal snap-acting SPDT switch, instead of the single pole/pointer contacts. When the switch closes on falling pressure, it becomes Set, as pressure rises the switch Resets , for three wire control; can be wired to make or to break a circuit.
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.
