Pirani vacuum gauge / digital

Measuring range: 1 mbar to approx. 10^-3 mbar.

The method is based on the thermal conductivity of gases. The gauges are also
known as Pirani instruments. The heated filament within the gauge head forms
one part of a controlled Wheatstone bridge. The required energy for heating
the filament depends on the pressure and therefore is a measure of the
pressure.

The pressure measurement is dependent on the type of gas.The devices are
variously applicable. The possible measuring range lies from the rough to the
fine vacuum range. The measured values are represented on
clear LED displays.
