20P7-HL-200: 2" Pressure Swichgage; Semi-automatic lockout; "FS" Contact; 0-100 psi (05703550)
The Murphy 0-200 PSI Mechanical Lockout Pressure Swichgage 2" with High/Low Contacts 20P7-HL-200 is a diaphragm-actuated, pressure-indicating gage with built-in electrical switch, which is used for tripping alarms and/or shutdown devices. The gauge 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 gage pointer acts as a pressure indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contacts are grounded through the Swichgage case and have self-cleaning motion to ensure electrical continuity.
This unit includes a front, semi-automatic lockout for startup override. This built-in device holds the pointer away from the contact on startup. When pressure exceeds the set point, the lockout is automatically disengaged.
Specifically designed to protect engines and equipment in Oil Field, Marine, Irrigation, Construction and Trucking applications to monitor Engine Lube Pressure, Water Pump Pressure, Hydraulic Pressure and Air Pressure.
