Do you know how bimetallic thermometer readings?

Bimetallic thermometer is a kind of measurement in the field of low temperature test 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. Do you know how bimetallic thermometer readings? Instrument to tell you! Bimetallic thermometer readings to let the sheath maerial of the thermometer to remain in the liquid or gas to be tested, the protection tube immersed in the measured medium length must be greater than the length of the thermal components, immersed in length is more than 100 mm, 0 50 ℃ range in more than 150 mm in length, so as to ensure the accuracy of measurement, and the line of sight to parallel to dial, don't look down and look up, so read data is not accurate. Reading to see how much range of bimetal thermometer, dividing value is how much, range is the range of the thermometer, dividing value refers to the thermometer every little represents how much above, it determines the precision of the measurement, we often use the index value of the thermometer is usually 1 ℃ or 2 ℃, and dividing values is Fahrenheit ( ℉) 。 Celsius ( ℃) And Fahrenheit ( ℉) The conversion relationship between the: F = 9 ℃ / 5 + 32, or 5 ℃ = ( F - 32) / 9 degrees Celsius; 9/5 + = 32 degrees Fahrenheit. According to the above introduction, everybody for bimetallic thermometer readings is there a more detailed understanding?
