An automatic fire alarm in a building's security system is a heat detector that responds to the heat from a fire by setting off an alarm. Some heat-detecting fire alarms rely on a bimetallic strip as the temperature sensor. This strip responds to heat by closing a normally open electrical circuit to activate the alarm.

WebA bimetallic strip converts thermal energy into mechanical displacement. What is Bimetallic Strip? Definition: A bimetallic strip works on the principle of thermal expansion, which is … WebDec 28, 2024 · The bimetallic strips are commonly used in thermostats. It is because the temperature change will bring the mechanical displacement in the metal. When the bimetallic strip is heated, the metal with higher thermal expansion will bend more. Thus they bend towards the metal having a lower thermal expansion.

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.
