Dial thermometers | Choosing the Right Thermometer
Mechanical gas expansion or liquid expansion thermometers are dial analog thermometers. They consist of a measuring tube with a reservoir inside and a Bourdon tube, which form a sealed pressurized system filled with a liquid or neutral gas. It is possible to place a capillary tube between the measuring tube and the Bourdon tube in order to move the dial away from the measuring point and take readings from several meters away. As the temperature rises, the...

How to choose this product
dial-thermometer

A dial thermometer measures temperature directly at a given point and without need for an electrical connection.
The temperature is indicated by a needle on a dial protected by a housing. Results are displayed in Celsius (°C), Fahrenheit (°F) or both.

Applications

Such devices are used at the measurement point. Unlike digital thermometers, they do not require a source of electric power. Stainless steel models are used in the chemical and pharmaceutical industries, as well as in agribusiness.

Technologies

Dial thermometers employ either a bimetal or gas expansion mechanism. The first takes advantage of the different linear expansion and contraction rates of two strips of dissimilar metals laminated together. One end of this assembly is attached to the needle. As the temperature changes, the strip bends, causing the needle to move.

How to choose

Choice will depend on specific intended use. Factors include the substance and range of temperatures to be measured and the measurement environment.
