Thermal resistance related knowledge

The typical use of thermal resistance is to measure the temperature of liquid, gas and surface of objects between -200℃~900℃ in industrial production process. Other uses include: measuring the point temperature of generator armature windings and excitation windings, pipes, headers and other narrow places; measuring the average temperature of indoors, spaces, containers and industrial production equipment; measuring surface temperature. The typical use of platinum thermal resistance as thermal resistance in calibration is to measure the temperature of liquid, gas and object surface at -200℃~900℃ in industrial production process. Other uses include: measuring the point temperature of generator armature windings and excitation windings, pipes, headers and other narrow places; measuring the average temperature of indoors, spaces, containers and industrial production equipment; measuring surface temperature. The platinum thermal resistance is used as a temperature standard in the calibration. 3. What are the characteristics of the thermal resistance wire for industrial use? The resistance wire for winding industrial resistance should have the following characteristics: (1) It should have a high temperature coefficient of resistance to obtain high sensitivity. It should have a high resistivity to obtain a small size and high resistance wire. (3) The resistance temperature characteristics remain stable during long-term use and in a wide temperature range. (4) In a wide temperature range and resistance range, temperature and resistance have a linear relationship. (5) High mechanical strength, able to withstand impulse, vibration and adjustment
