Bimetallic thermometer heat tube how to customize?

Bimetallic thermometer is a professional instrument in measuring low temperature field temperature, its working principle is based on the principle of solid heat expansion, the two pieces of expansion coefficient difference is very big pieces of metal welded together. When the temperature changes, the difference is very big, caused the different expansion coefficient of expansion and contraction, the deformation of sheet metal bending. According to different deformation and produce different momentum, momentum to drive the connection shaft and the other end of the indicating needle, indicate the temperature. According to different usage environment, the bimetallic thermometer length and diameter of the heat pipe is very different, so the bimetallic thermometer heat tube how to custom? Customize the bimetallic thermometer heat pipe if you want to know the two parameters, one is the heat pipe diameter, another is heat pipe length. We often use more than the diameter of the bimetallic thermometer is 6 mm, and 6. 35 mm, 8 mm and 10 mm, when the choice according to the inner diameter of the selected nipple choose matching; And the length of the heat pipe is related to the depth of the measured medium, typically heat pipe need to insert depth more than half of the measured medium, the measured temperature value is relatively accurate. If still don't know when the choose and buy, or worry about mistaken, can tell us all the parameters directly, we will help you determine the suitable heat pipe length.
