OPLC-A-1000: 4.5" Pressure Swichgage; surface mounting; 0-1000 psi (05700663)

The OPLC-A-1000 is a surface mounting 4.5" (114 mm) Pressure Swichgage, with a range of 0-1000 psi (0-6.89 MPa) [0-70 bar].

This instrument is a combination pressure indicating gage with an adjustable low and high limit switch. The limit switch can be wired directly to electric pilot circuits to operate alarms and/or shutdown engines and electric motors. The limit switch is accessible from the front of the gage and the contacts have a self-cleaning motion to enhance electrical continuity.

Inside the OPLC-A-1000, 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 start-up. This model does not latch. Suitable for engines or electric motors with appropriate Murphy magnetic switch or transformer relay assemblies.

The OPLC-A-1000 has a weatherproof die cast aluminium case, a clear polycarbonate lens, a 1/4 NPT process connection, a grade A phosphor bronze bourdon tube (brass tip/silver brazed) and a brass socket.
