Arun PV3 Pirani Gaugeheads

Pirani gauges detect the cooling effect of residual gas molecules on a heated filament. The rate of heat transfer to the gas is related to pressure and causes a change in the electrical resistance of the filament or the amount of power required to maintain it at constant temperature. The filament is normally connected in a bridge circuit.

Features:

  • Range: 200 mbar to 1 x 10-3 mbar
  • Intended for use in constant-voltage bridge circuits, which reduces the filament temperature and the rate of filament corrosion or contamination at high pressures
  • May be interchanged between any AML NGC / PGC series or equivalent controllers without recalibration
  • Integral 3-metre lead and connector
  • Extension cables do not affect the calibration
  • Mounts in any orientation
  • 200°C bakeable version available
  • RoHS compliant
