WebNov 6, 2024 · In This Article. 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. 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.

"WebBimetallic jumping discs work similarly to bimetallic strips, except they are circle-shaped. Jumping discs do not come perfectly flat, however — they are slightly bowed in one direction. When they are heated past a certain temperature, the jumping discs "snap through" in the other direction. Then, as they cool down, they snap back through to ... " - How do bimetallic strips work

How do bimetallic strips work

WebA bimetallic strip is used to convert a temperature change into mechanical displacement. The principle is that as the temperature changes, one strip will expand more than the other causing the pair to bend at the free end. WebApr 22, 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.
