Explosion-proof: Swichgage enclosed within explosion proof case Class I, Div.

Class I, Division 1, Groups C & D hazardous applications.

High and Low Pressure Limit Contacts Are Visible and Adjustable.

Combination Indicating Gage and Critical Pressure Limit Switches.A method to override the low limit contact for start-up is provided on OPLC models. OPLC gage instruments have high and low limit contacts to monitor, alarm or shut down. Suitable for engines or electric motors with appropriate Murphy magnetic switch or transformer relay assembly. FW Murphy - OPLC-S-5000-EL: 4.5' Stainless Pressure Swichgage® surface mount w/ low limit lockout switch 0-5000 psi Explosion-proof less case. Pointer closure against either of the adjustable contacts completes the pilot-duty circuit.Īn SPST toggle switch is provided to override the low limit contact for equipment startup. Adjustable high and low limit, ungrounded contacts are used to operate alarm, shutdown or start-stop circuits.

The OPLC is a surface mount, indicating, pressure gage and switch. Adjustable limit switch is accessible from the front of the gage and the contacts have a self-cleaning motion to enhance electrical continuity. This limit switch can be wired directly to electric pilot circuits to operate alarms, shutdown or start/stop of engines and electric motors. The Murphy Explosion-Proof 0- 5000 PSI Surface Mount Pressure Swichgage with Low Limit Lockout Switch OPLC-S-5000-EX is a combination pressure indicating gage with adjustable low and high limit switch.
