The Murphy 0-200 PSI Panel Mount Mechanical Pressure Swichgage with Bronze Bourdon Tube and PT167 Pressure Transmitter OPLFC-A-200-OS-P6 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-200-OS-P6 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.

The P6 (was PT167) option is a diaphragm sealed to a 2 NPT housing which attaches directly to the pressure gage connection. The gage sensing element and the diaphragm chamber are filled with a silicone fluid so that pressure against the diaphragm causes the gage to respond. The diaphragm housing is plated machined steel. Typical application is for oil well lead lines. Ranges 100 thru 1,000 psi (689 kPa thru 6.8 MPa) [6.89 thru 68.9 bar].
