Murphy 0-300 PSI Panel Mount Mechanical Pressure Swichgage with Bronze Bourdon Tube - OPLFC-A-300

The Murphy 0-300 PSI Panel Mount Mechanical Pressure Swichgage with Bronze Bourdon Tube OPLFC-A-300 is a combination pressure indicating gage with adjustable low and high limit switch. This limit switch can be wired directly to electric pilot circuits to operate alarms, shutdown or start/stop of engines and electric motors. The OPLFC-A-300 features a 4-1/2 in. (114 mm) dial for easy viewing. Adjustable limit switch is accessible from the front of the gage and the contacts have a self-cleaning motion to enhance electrical continuity.

The OPLFC is a panel mounting version of the OPLC. It has all of the features of the OPLC except the low limit contact lockout. The lockout must be done externally through the control circuit or with the optional “SA” lockout. The OPLFC is typically used in control panels such as for compressors, pumps, etc. This version can be environmentally sealed with either the “ES” or “OS” options. Contact lead termination is by pigtail wires.
