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 environment

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.

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. 

Applications

The 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) Dial
  • Corrosion Resistant Polycarbonate Case
  • Indicating Gage and Limit Switch
  • Switch Can Activate Alarms and/or Shut Down Equipment
  • Critical Pressure Limit Switch Is Visible and Adjustable (Most Models)
  • Contact(s) Isolated From Ground
  • The 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. When the switch closes on falling pressure, it becomes Set, as pressure rises the switch Resets (refer to wiring diagram).
  • Includes internal SPDT snap-switch for pre-alarm.
