This temperature is depending on the rate at which the filament loses heat for the surrounding gas, and as a consequence to the thermal conductivity. A standard variant is the Pirani gauge which takes advantage of just one platinum filament as both the heated aspect and RTD. These gauges are exact from 10 torr to ten−3 torr, but These are sensitive to your chemical composition in the gases remaining measured.
