They are used in thermostats as a physically temperature sensitive switch. Because the two different metals expand and contract at different rates when bimetals are wound into coils the coils become temperature sensitive and expand and contract with respect to the ambient temperature.

Who invented the bimetal thermometer?
John Harrison
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 apparatus used to measure temperature?
We can use thermometers, thermocouples, thermoresistances, pyrometers etc.
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.
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.
How does a dial thermometer function?
Most dial thermometers use a bimetal spring to drive the pointer on the the thermometer face. Two metals are laminated together and wound to form the spring. One metal expands (or contracts) more rapidly than the other due to temperature changes. As the spring's shape changes the pointer moves accordingly. Another type of dial thermometer uses temperature-sensitive gas in a sealed tube to drive the point.
Use in a sentence for thermometer?
use thermometer in fever.
How can you measure a body temperature?
What kind of thermometer you use to measure the body temperature
Where does the thermometer be used at?
Depends on the thermometer. If it's a weather thermometer, then you use it outside. If it's a body temperature thermometer, then you use it in the mouth or behind.
When would you use regular thermometer?
Use a regular thermometer to test your body (or a child's body) for fever. Use a meat thermometer when cooking meat, and an outdoor thermometer to check the weather outside.
How do you use a science thermometer?
The same way you use a non-science thermometer.
If you want to get the temperature of the water what instrument will you use?
I would use a thermometer.
