The measuring system of the gas pressure thermometer comprises probe, capillary tube and Bourdon tube in a casing. These parts form a unit. The complete measuring system is filled with pressurized nitrogen. A change in temperature causes a change in inner pressure in the immersion shaft.


The resulting deflection of the Bourdon tube is transferred to the pointer through a pointer element. Display and probe are connected by a capillary tube separated by a distance up to 100 m. A version filled with glycerine is available as an option for service at measuring points exposed to strong vibrations.


The fill dampens the measuring system when exposed to mechanical vibrations and thus enables steady indication; it also provides good lubrication for moving parts. We recommend our robust aluminium casing for rough field service conditions. These thermometers can also be used with aggressive measuring substances when fitted with a suitable thermowell.
