Temperature of a body is defined by the thermic expansion
Gas Actuated Thermometers work on pressure or volume change of a gas. That means the temperature of a body is defined by the thermic expansion (the measurement of length or volume change).
The filling compound is located in a vessel. The temperature change causes a system pressure increase or drop that can be read off the scale by using a bourdon tube pressure system.
BITHERMA Gas Actuated Thermometers are offered in various versions and with many connectivities.

Gas-Pressure Thermometers: Precisely Measuring Thermal Expansion
Measuring the temperature in your machines and systems is essential for optimal manufacturing conditions and workplace safety. To obtain reliable readings with minimal variance, using a high-quality gas-pressure thermometer is crucial. At BITHERMA, we offer this specialized thermometer in a chemical-resistant design, along with a range of practical connection options.
What Are Gas-Pressure Thermometers Used For and How Do They Work?
These thermometers are used wherever you need to precisely detect and control temperature changes in your systems and machinery. They are always mechanical dial thermometers operating on the principle of thermal expansion. Temperature changes are detected through the expansion of a medium and displayed on the dial.
Accurate temperature monitoring is especially important for safety reasons. Excessive temperatures within a system can have serious consequences for your machinery and operating personnel. Functionally, temperature control is also important, as many systems and machines must operate within a specific temperature range. You can ensure this control with a BITHERMA gas-pressure thermometer.
These thermometers are filled with an inert gas or alcohol and operate on the expansion principle—meaning the thermal expansion of the gas determines the temperature of the medium. If the temperature rises or falls, the system pressure changes at a constant volume. The thermometer detects this and displays the change on the dial via a Bourdon tube measuring system.
Gas-Pressure Thermometers and More from BITHERMA
At BITHERMA, you’ll find your specialized thermometer. In the chemical-resistant version, the device is entirely made of stainless steel. The sensing element is manufactured to your specifications in both length and diameter. For connections, you can choose between a rear, vertical, or angled version. Of course, remote-reading models are also available.
Tension Thermometers with Alcohol Filling
For simpler applications, our galvanized standard version is the right alternative. The sensor is made from a copper alloy or other material according to your requirements. For installation, a three-point ring with clamp bracket is standard. Other mounting options are also available.
