How do bimetallic strips work

WebFeb 9, 2024 · The bimetallic strip is hooked up to the needle of the gauge through a linkage. The bimetallic strip is a piece of metal made by laminating two different types of metal together. The metals that make up the strip expand and contract when they are heated or cooled. Each type of metal has its own particular rate of expansion. WebIt works because metals expand in different ways when temperature rises. Metal expands when temperature rises - in general, anyway, but not all metals expand the same. Then, if you take two different metals, typically iron and copper, and bind them together in both ends, one metal will try to become longer than the other as the temperature rises.

This effect is used in a range of mechanical and electrical devices. Mechanical clock mechanisms are sensitive to temperature changes as each part has tiny tolerance and it leads to errors in time keeping. A bimetallic strip is used to compensate this phenomenon in the mechanism of some timepieces. The most common method is to use a bimetallic construction for the circular ri… WebThe working of the bimetallic strip depends on the thermal expansion property of the metal. The thermal expansion is the tendency of metal in which the volume of metal changes with the variation in temperature. Every metal has a different temperature coefficient.
