The Murphy 0-30 PSI Mechanical Pressure Swichgage with Internal Snap-Acting SPDT Switch 20PE-30 is a diaphragm-actuated, pressure-indicating gage with a built-in electrical switch. This swichgage is used for tripping alarms and/or shutdown devices. The gage mechanism is enclosed in a steel case coated to resist corrosion. A polycarbonate, break-resistant lens and a polished, stainless steel bezel help protect this rugged, built-to-last instrument. 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 20PE-30 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. Specifically designed to protect engines/equipment in oil field, marine, irrigation, construction and trucking applications to monitor engine lube pressure, water pump pressure, hydraulic pressure and air pressure.
