The Murphy Pressure Swichgage A25PE-300 is a diaphragm-actuated, pressure-indicating gage with built-in electrical switch for tripping alarms and/or shutdown devices. This rugged, built-to-last instrument is face sealed from the environment by the unique combination of a polycarbonate case and lens, a polished stainless steel bezel and O-ring seal. Accuracy and protection from moderate overpressure is assured by a unique, unitized diaphragm chamber. A built-in pulsation dampener helps eliminate pointer flutter and is removable for cleaning. It also features an internal snap-acting SPDT switch for three wire control and can be wired to make or to break a circuit. The switch trip point cannot be set at either the low or high extreme of the scale. The trip point must allow for the reset differential.
Applications for this instrument includes: engines/equipment in oil field, marine, irrigation, construction and trucking for lube oil pressure, water pump pressure, hydraulic pressure, air pressure, etc.
PRODUCT FEATURES:
- 2-1/2 inch/64 mm dial
- Features internal snap-acting SPDT switch, instead of the single pole/pointer contacts. When the switch closes on falling pressure, it becomes set, as pressure rises the switch resets
- Comply with EMC Council directive 89/336/EEC regarding electromagnetic compatibility except as noted
- CSA listed for non-hazardous areas
