FRANK W. MURPHY PRESSURE GAUGE, OPLE-A-30-EX, 125 VAC, 1 A, 207KPA/ 300 PSI

The Frank W. Murphy OPLE-A-30-EX is a 4-1/2 in (114 mm) dial pressure instrument from FW Murphy's OPL Series, a family of combination indicating gauges with adjustable limit contacts that wire straight into pilot circuits to raise an alarm, shut equipment down, or start and stop engines and electric motors. Decoded against Murphy's published OPL ordering guide, this configuration pairs a Grade A phosphor bronze bourdon tube on a 1/4 NPT connection (code A) with a 0-30 psi / 0-207 kPa dual-scale dial (code 30) and the EX option, an explosion-proof case rated for Class I, Division 1, Groups C and D locations — the reason these instruments are a fixture on gas-compression skids, oilfield engine panels, and pump stations.

This listing is for the gauge shown: one US-made OPLE-A-30-EX, nameplate-rated 125 VAC, 1 A, in line with the SPDT center-off pilot-duty contact rating Murphy publishes for OPL-series instruments (2 A at 30 VDC / 1 A at 125 VAC). The OPLE base designation no longer appears in Murphy's current OPL literature, which makes surplus stock the practical way to source a like-for-like replacement — while every suffix on the part number still decodes exactly against Murphy's current ordering guide.
