Pressure Measurement & Control

Pressure Gauge Code 91

The Conflow Code 91 - Pressure Gauge is a traditional bourdon tube type unit, but designed specially for hazardous environments.

The case of the gauge is exceptionally robust to withstand external damage in tough and arduous areas. Internally, facilities for damping out hydraulic oscillations are built in to enable steady pressure readings to be taken close to triple ram pumps.

When the gauge is screwed into place by means of the hexagon shank, the whole carcass of the unit can be rotated by hand until the most readable dial position is presented.

Typical Applications

  • Checking water circuit system pressures on coal cutting machines
  • Checking mains water pressures in underground mines at various points throughout the mine
  • Checking feed and return line hydraulic pressures on roof support systems


  • 3/8" BSP fitting (1/4" available on request)
  • Pressure ranges from 20 to 1000 bar
  • Horizontal and vertical mountings
  • Robust design, ideal for arduous mining conditions
  • Case can be turned to give optimal viewing position
  • Bezel rotates to set red line dial marker
  • Constructed with safety blow out plug
