Industrial dial thermometers

The measure principle is based on a tank located in the lower part of the stem, filled with gas (normally Nitrogen) at a certain pressure, associated to a Bourdon tube and a manometric mechanism. The variations of the temperature expands or contracts the gas, causing the movement of the Bourdon tube and therefore the indicator needle.


Gas-actuated industrial dial thermometers, fully stainless steel, rugged construction.
Available in Ø 100 and 150 mm.
Available for local or remote mounting, by means of a flexible capillary tube.
