Pirani Gauge Heads and Leads

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.


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
