Gas Actuated Thermometer

The measuring system in the gas thermometers consists of the stem, capillary and Bourdon tube in a case. These parts are connected to form a unit. The complete measuring system is filled with an inert gas under pressure.

A temperature change causes the internal pressure in the stem to change. The deflection of the Bourdon tube thus caused is transmitted to the pointer by a movement.

An extensive range of standard versions facilitates a variety of applications. In addition, special customised versions are available. Thermowells for screw or welded fitting are available in copper alloy, steel and stainless steel materials.
