Gas Actuated Thermometers

If your application requires a more robust design than a Bimetal Thermometer and have the capability to measure higher temperature readings, then Gas Actuated Thermometers may be a better fit in your application.

They can also be known as Gas Filled Thermometers, or Gas Expansion Thermometers. They employ the use of a small amount of stable gas in the ‘bulb’ or ‘insertion tube’ which expands at a predictable rate. It is the expansion of the gas that is monitored through mechanical linkages and translated into a rotational movement as the pointer moves around the dial, giving the visual temperature indication.

Gas Expansion Thermometers are available with a wide range of options, and can offer accurate visual temperature readings from -200…800°C. Versions are available with up to IP68 Ingress Protection and ATEX versions are avialable for use in potentially epxplosive atmospheres. They are also available with a ‘capillary’ meaning the thermometer can be mounted up to 30m away from the application. This is particularly useful in applications where ambient temperature is high.
