The Murphy 0-100 PSI Surface Mount Pressure Swichgage with Low Limit Lockout Switch OPLC-A-100 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 OPLC-A-100 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 OPLC is a surface mount, indicating, pressure gage and switch. Adjustable high and low limit, ungrounded contacts are used to operate alarm, shutdown or start-stop circuits. Pointer closure against either of the adjustable contacts completes the pilot-duty circuit.
An SPST toggle switch is provided to override the low limit contact for equipment startup. Suitable for engines or electric motors with appropriate Murphy magnetic switch or transformer relay assembly.
