The Murphy Pressure Swichgage 25P-HL-300 is a diaphragm-actuated, pressure-indicating gage with built-in electrical switch. This switch exceed SAE standards and is used for tripping alarm and/or shutdown device. 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. The gage pointer acts as a pressure indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. A built-in pulsation dampener helps eliminate pointer flutter and is removable for cleaning.

The Swichgage was 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, air pressure, etc.
