Explanation about the usage of heat resistance

The use for common of thermal resistance in low temperature area, used mainly as a temperature detector, the characteristics of the thermal resistance is, therefore, the precision of the measurement is very high, and the performance is stable. But platinum-rhodium thermal resistance is on measuring the degree, thermal resistance not only use in industrial temperature measurement, but also often was made into a standard benchmark instrument to use.

due to the thermal resistance in the temperature measurement, mainly based on the metal conductor, so the resistance value will change because of the increase of temperature, thermal resistance is basic it is made from pure metal materials, widely used at present in the market should be copper and platinum, but also began to use materials such as manganese, survey, rhodium and nickel to make thermal resistance. In the thermal resistance of the industry, often using the resistance of the temperature sensing element, its structure and characteristics are special, but from the principle of thermal resistance temperature measurement to understand the words, the changes in temperature being measured, directly through the thermal resistance value of the measurement, so the heat resistance of lead wire, such as a variety of wire resistance on the change, the measuring of temperature will bring great influence.
