How it Works and Features of Bimetal Thermometer1. How it Works
The work of this bimetallic thermometer is based on the fact that two dissimilar metals behave in different ways when exposed to temperature variations due to different rates of thermal expansion. One metal layer expands or contracts more than the other metal layer in a bimetallic arrangement resulting in a change in bending or curvature of the strip.
The working principle of a bimetallic thermometer can also be likened to this: “One end of a straight bimetallic strip is fixed in place. When the strip is heated, the other end tends to bend away from the side with the larger coefficient of linear expansion. ”2. Main Features
This type of thermometer works best at higher temperatures, as its accuracy and sensitivity tends to decrease at lower temperatures.
The Bimetal thermometer can be adjusted to work as a recording thermometer as well by affixing the pen to the pointer. This pen is located in such a way that it can make recordings on a rotating graph.
