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?
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 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 and disadvantage of using alcohol in thermometer?
u don't have to flick the thermometer to reset the temperature reading when you use an alcohol based thermometer (unlike a mercury thermometer where you have to flick and flick and flick flick flick that thermometer for the mercury to be reset so that you can make an accurate reading) a disadvantage is that the alcohol thermometer is slightly less acurate The biggest advantage is that alcohol is not nearly as toxic as mercury, so that if the thermometer breaks, you won't be poisoned.
What are the advantage of using Mercury in thermometer?
it can be easily seen it gets hot quickly it expands fast.. this is the advantage of mercury in thermometers..
What are the advantages and disadvantages of a electronic ear thermometer?
Advantage : easy to read and use
What are the advantages and disadvantage of digital thermometer?
Can anyone plz tell me what are the advantage and disadvantage of digitaland
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.
What is the use of bimetal thermometer?
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.
What two metals make up a bimetal?
Brass and Iron
What are the advantages and disadvantages of paperless input design?
The advantage of an electronic office is that all the records are automated and can therefore be easily retrieved. The disadvantage of electronic office is that they are expensive to set up.
