A bimetallic strip is used to convert a temperature change into mechanical displacement. The strip consists of two strips of different metals which expand at different rates as they are heated, usually steel and copper, or in some cases steel and gakulkarni.info strips are joined together throughout their length by riveting, brazing or gakulkarni.info different expansions force the flat strip to bend. This back and forth movement of strip can be used in many applications such as to turn on/off a switch or regulate a valve. Bimetallic strip in thermostat. A thermostat is a practical application of the bimetal strip and the bimetal strip is probably the most important piece in a thermostat. A thermostat has 3 important main components.
Aug 14, · Bimetallic strips. A traditional thermostat has two pieces of different metals bolted together to form what's called a bimetallic strip (or bimetal strip). The strip works as a bridge in an electrical circuit connected to your heating system. Normally the "bridge is down", the strip carries electricity through the circuit, and the heating is on.

When heated, the metal strip deforms due to the different degrees of expansion. The deformation is a measure of the temperature and can be read off a calibrated scale. Figure: Structure and principle of a bimetallic strip. In bimetallic strip thermometers the different rates of expansion of metals when heated is used to measure the temperature!Author: Tec-Science. Decide on the purpose of your bimetallic strip. Bimetallic strips are usually used to make a mechanical part move in a given direction, often to connect to another mechanical part. This can either set a process of mechanical movement in motion, or create an electronic connection. Decide which way your bimetallic strip needs to move.
Bimetallic strip. The thermostat in an iron uses a bimetallic strip, and as the name implies, a bimetallic strip is made up of two different types of metal – with dissimilar coefficients of expansion – that are bonded together. This means that in the presence of heat, they expand differently. This bimetallic strip is connected to a contact Author: Ashish.
