Murphy - 2 inch Swichgauge 150PSI - A20PABS-150
The A20PABS-150 (2 inch/51 mm dial) Swichgage instruments are diaphragm-actuated, pressure-indicating gages, with built-in electrical switches for tripping alarms and/or shutdown devices. The pressure range is 0-150 psi (690 kPa) [6.9 bar]. This is a rugged, built-to-last instrument and the face is sealed from the environment by the unique combination of a polycarbonate case and lens, a polished stainless steel bezel and O-ring seals. Ranges above 30 psi (207 kPa) [2 bar] are totally sealed from the external environmentAccuracy 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.On the A20PABS-150, the gage pointer acts as a pressure indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contacts have self-cleaning motion to ensure electrical continuity.  They also have internal snap-acting SPDT switches for three wire control; can be wired to make or to break a circuit. ApplicationsThe A20PABS-150 applications include: engines/equipment in Oil Field, Marine, Irrigation, Construction and Trucking Engines for Lube Oil Pressure, Water Pump Pressure, Hydraulic Pressure, Air Pressure, etc.Features: A20PABS-150Series Swichgage:2 and  (51 and 64 mm) DialCorrosion Resistant Polycarbonate CaseIndicating Gage and Limit SwitchSwitch Can Activate Alarms and/or Shut Down EquipmentCritical Pressure Limit Switch Is Visible and Adjustable (Most Models)Contact(s) Isolated From GroundThe gage pointer makes with an adjustable contact to complete a pilot-duty circuit.Features internal snap-acting SPDT switches, instead of the single pole/pointer contacts.
