Oct 02, 2018 · As the name implies, a bi-metal thermostat consists of two different metals riveted together to form a compound strip. The two metal strips are bonded together under heat and pressure. The thermal energy can be converted into electromechanical motion by employing different expansion rates or linear expansivity on two metals.

This consists of a strip of brass in contact with a strip of iron. At normal room temperature, the two strips have the same length. However, since brass expands (or contracts) more than iron when its temperature is raised (or cooled), the bimetallic strip will bend one way or another depending on the temperature being above or below room ...

6.3.4: A bimetallic thermometer. It is made up of a coiled bimetallic strip whose one end is fixed and the other end connected to a pointer. Commonly used metals are brass and invar. When the temperature rises brass expands more than invar. The strip thus curls forcing the pointer to move over a calibrated scale. 6.4: Expansion in solids

By forming a bimetal strip into a dome shape (hemispherical, dished shape) to acquire snap action, the disk type thermostat is characterized by its simplicity of construction. The simple design facilitates volume production and, because of its low cost, account for 80% of the entire bimetallic …

Fire Alarm Introduction A fire alarm is used to warn people when there is a fire.

By contrast, a mechanical thermostat usually controls the temperature with the use of two bits of metal. These are laminated together in the thermostat’s sensor in a bimetallic strip. As the different types of metals expand and contract with temperature changes, an electric circuit connected to your heating system is switched on and off.

The ampoule is attached to a coiled bimetallic strip, also called a bimetallic coil. As the coil moves, it tips the vial of mercury until the mercury moves and the switch contact is opened or closed. Finally, the heat anticipator is an electrical resistance wire mounted on a center disc connected to the bimetallic coil.

A strip made from permanently-laminated rolled sheets, made from metals having different coefficients of expansion ("bimetal"), will bend as a result of any temperature changes. The bending is roughly proportional to the change in temperature.
