A bi-metal strip can be used as a thermostat. It consists of two metals that expand by different amounts when the temperature changes, so it will bend when heated. When the temperature is hot, the switch will close. When it is cold, the switch will open. They are not as accurate and quick to respond as sensors, yet they are less expensive.

Why are two different metals used to produce movement in bimetal elements?
Two different metals are used in bimetal elements because they have different coefficients of thermal expansion. When heated or cooled, these metals expand or contract at different rates, causing the bimetal strip to bend. This bending motion is used for various applications such as in thermostats or circuit breakers.
Can one produce energy with a bi metal strip when heated?
Yes, a bimetal strip can be used to produce energy when heated by converting the thermal energy into mechanical energy. When the bimetal strip bends due to differential expansion of its constituent metals, this mechanical energy can be harnessed to perform work or generate electricity using a suitable mechanism like a generator.
Which way does a bimetal bend when heated?
When heated, a bimetal strip bends towards the side with the material that expands more quickly. This is because the faster-expanding material creates a greater force on that side, causing the strip to bend in that direction.
What is the bimetal mechanical thermometer?
The bimetal mechanical thermometer uses one end of a bimetallic coil connected to the housing of the device and the other end drives an indicating needle. The bimetal mechanical thermometer is often used in things like refrigerators, air conditioners and heat control.
What is a bimetallic strip used in?
Bimetal strips can be used for thermocouples. The two metals will have different expansion rates and the difference will generate a small amount of electricity. The electricity generated can be collated to a given temperature. Your mom

How can the bimetal strip be extended to have more travel per degree of temperature change?
Increasing the length or thickness of the bimetal strip can provide more travel per degree of temperature change. Additionally, using bimetal strips with different types of metals or coatings can also help achieve greater movement for a given temperature change.

What is a bimetic strip?
A bi-metal strip is a bimetallic strip that is used to convert temperature changes into mechanical movement. It consists of two metals that expand by different amounts when the temperature changes, so it will bend when heated.
What does a bimetal thermometer do?
A bimetal thermometer is two strips of different metals that have been stuck together. because the two metals will have differing rates of expansion under heat, the strip will bend towards one side. if the thermometer is colder than standard temperature, the strip will bend towards the side with a higher expansion rate, and if it is hotter, than it will bend towards the metal with the lower expansion rate. Because the expansion is a fixed property of a metal, a bimetal thermometer will have a relative accuracy because of them.

What is the advantage of bimetal thermometer?
A biometallic thermometer measures temperature. It uses a differential thermal expansion of metals that are bonded together into a strip. Another name for these thermometers is differential thermometer.
Who invented the bimetal thermometer?
The bimetal thermometer was invented by Johan August Arfwedson in 1860.
A bimetal strip has two metals of different?
It depends on the properties you want. A good chart is provided by EMS at http://www.engineeredmaterialssolutions.com/6-clad_solutions.html that lists applications and the types of bonded material to use.
