2.2 Description

The gas-actuated thermometer consists of a stem, capillary, Bourdon
tube and transmitter in the case. These parts are combined to form a
single unit. The entire measuring system is filled with an inert gas under
pressure.
Any change in temperature causes a change in internal pressure in the
stem, and thus a change in the shape of the pressure element.
