Do you know how bimetallic thermometer readings?1

Bimetallic thermometer readings? Below small make up to solve for you: double metal thermometer to two different linear expansion coefficient of metal together, one end fixed, when the temperature changes, the two different kinds of metal thermal expansion, drive the pointer to indicate the temperature, that is the bimetallic thermometer. Bimetallic thermometer is a measurement of low temperature field testing instrument. Bimetallic thermometer can be directly measured in the process of various production - 80 ℃ ~ + 500 ℃ within the scope of liquid, steam and gas medium temperature. Read bimetallic thermometer readings is the final measurement results. To observe the range of the thermometer and dividing values. Range is the range of the thermometer, such as the range of 0 - our common thermometer 120 ℃, dividing value refers to the thermometer every little represents how much above, it determines the accuracy of the measurement, we often use the index value of the thermometer is 1 ℃ or 2 ℃, see the range of the thermometer and after dividing values we can use the hands of the thermometer to measure the temperature of the liquid or gas. Some customers need bimetallic thermometer with Fahrenheit, letters & quot; F” Said. Celsius ( ℃) And Fahrenheit ( ℉) The conversion relationship between the: F = 9 ℃ / 5 + 32, or 5 ℃ = ( F - 32) / 9 c & times; 9/5 + = 32 degrees Fahrenheit. We should pay attention to is: double metal thermometer readings to let the sheath maerial of the thermometer to remain in the liquid or gas to be tested, and the line of sight to dial to the flat. Look down and look up in the reading results are not accurate.
