Thermal Conductivity Vacuum Gage
</dt>
A vacuum
gage containing two surfaces at different temperatures between which heat
can be transported by the gas molecules so that changes in the temperature (or
in the heating power required to maintain constant temperature) of one of the
surfaces can be correlated with the gas pressure by calibration against a McLeod
gage. Various types of thermal conductivity gages are distinguished
according to the method of indicating the temperature change. The common type
are: Pirani gage; thermocouple gage; thermistor gage; bimetallic strip gage.
