Can bimetal thermometers be used when the using ambient temperature is 300C?
- Issue Time
The working principle of bimetal thermometer is to weld two pieces of metal with great difference in expansion coefficient together.
The working principle of bimetal thermometer is to weld two pieces of metal with great difference in expansion coefficient together.When the temperature changes, the different expansion coefficient results in different expansion and contraction, resulting in the bending deformation of the metal sheet.According to the different deformation, different rotation amount is generated. The rotation amount drives the connected rotating shaft and the indicator needle at the other end to indicate the temperature.It can directly measure the temperature of liquid, steam and gas in the range of - 50 ℃ to + 500 ℃ in various production processes.
The figure below shows a bimetal thermometer commonly used in Chinese instruments and equipment.
