The Murphy Swichgage 0-200 PSI Mechanical Pressure Gauge 2" with High/Low Contacts and Knob Adjusting Face Contact A20P-HLK-200 is a diaphragm-actuated, pressure-indicating gage with a built-in electrical switch for tripping alarms and/or shutdown devices. 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.
This Swichgage A20P-HLK-200 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.
