Pressure Gauges

Duplex Differential Pressure Gauge

 BACK to Pressure Gauges
  • Diameter 100mm.
  • Measuring Ranges from 0-1 up to 0-40 BAR.
  • Central Differential Scale.
  • Heavy Duty Phospher Bronze Bourdon Tubes (up to 200oC).
  • Coloured Scales in PSI/BAR, MWs/BAR and BAR Only.
  • Monobloc Connectors.

Comprises two identical and indepentent Bourdon Tube pressure measuring Systems with both pointer rotating on the same axis. A graduated disc is attached to one pointer to provide direct readout of the differential pressure.
These gauges provide a most economical method of measuring the difference in pressure between two points e.g. indication of pressure differential across a filter shows when it is becoming clogged or flow rate through an orifice plate etc.
