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.
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
