Murphy 2-1/2 in. Mechanical Pressure Swichgage 100 PSI with Internal SPDT Snap-Switch for Pre-Alarm - A25PABS-100
The Murphy Pressure Swichgage A25PABS-100 features a standard limit contact for equipment shutdown on low pressure. They also have an internal SPDT snap-switch to signal an alarm before shutting down. When the snap-switch trips (preset point) on falling pressure, the switch completes a circuit to activate an alarm. If the pressure continues to fall, the face-adjustable pointer contact will make and the shutdown circuit will be completed (see the typical diagram Image 3 for reference). The front contact shutdown limit setting (which is adjustable) and the snap-switch are preset at the factory.  It is a diaphragm-actuated, pressure-indicating gage with built-in electrical switches 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. A25 Series applications include: 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 dialThe gage pointer makes with an adjustable contact to complete a pilot duty circuitInternal SPDT snap-switch for pre-alarmSealed from the external environmentPRODUCT SPECIFICATIONS:Murphy Part No.: A25PABS-100Series: A25 SeriesBase Model: A25PABSRange: 0-100 psi (0-689 kPa) [7.0 bar]Dial: White on black, dual scale; U.S.A. standard scale is psi/kPaCase: Polycarbonate/glass filled, corrosion-resistantBezel: Polished stainless steel, standardPointer: Tempered nickel silver; Red tipLens: Polycarbonate, high-impactTemperature Range:Ambient: -40° to 150°F (-40° to 66°C)Process: -40° to 250°F (-40° to 121°C)Process Connection: 1/8-27 NPTM brassSensing Element: Beryllium copper diaphragmGage Accuracy (% of Full Scale): Lower 1/4: ±3%Middle 1/2: ±2%Upper 1/4: ±3%Maximum Pressure: 200 psi (1.4 MPa)Standard Setting: 20 psi (138 kPa) [1.5 bar]Low Setting: 20 psi (138 kPa) [1.0 bar]Alarm Setting: 23 psi (159 kPa) [1.5 bar]Adjustable Limit Contact: SPST contact; pilot-duty only, 2A@30 VAC/DC; Closed when the low limit is met.
