Embodiment 1
[0035] The specific measurement process is: the length of the capillary of the thermometer is 6 meters, the measuring range of the thermometer is 100 ℃, and the measurement preparation is carried out according to the above measurement method at an ambient temperature of 25 ℃. The heating area of the capillary is 0.5 m in length. At the same time, read the thermometer value and torque value. If the reading temperature is 25.0℃, the torque is 0.43N·m;
[0036] Set the temperature of the temperature control device and stably increase the temperature to the set value of 55°C. After stabilization, read the thermometer value and torque value. For example, the temperature is 25.2°C and the torque is 0.45N·m;
[0037] The calculation is as follows: the temperature difference of a 0.5-meter capillary is 0.2℃, and the torque difference is 0.02N·m; therefore, when the temperature of a 6-meter capillary changes by 30℃, the thermometer can produce a temperature difference of 2.4℃ and a torque ...
