What are the structure types of thermal resistance?

In different environments, if you want to measure the temperature in the environment, you need to use professional equipment. Moreover, you have to choose the corresponding equipment according to different environments, so that you can measure the temperature in the environment. Thermal resistance is a kind of commonly used temperature measurement equipment. So, what are the structure types of thermal resistance? How to choose the thermal resistance of different materials?

1. Common structure types

When you buy thermal resistance equipment, you usually encounter two types of thermal resistance, one is the wire-wound element type, and the other is the thin-film element type. These two thermal resistances can measure the temperature of different environments. Among them, the common wire-wound element type electric heating group and the film type thermal resistance are suitable for the environment where the installation location is relatively small and the temperature measurement system is relatively high. You can choose suitable measurement equipment according to the needs of the measurement environment.

two. The characteristics of different materials

Although ceramic thermal resistance can be applied to particularly low and particularly high temperatures, its anti-vibration ability is not very high; glass material not only has the advantage of heat shock resistance, but also has strong anti-vibration ability. In addition, the silicon chip material is suitable for thin-film thermal resistance equipment.

3. Common troubleshooting methods

When using thermal resistance equipment, you can often see that the displayed value of the meter is lower or unstable than the actual value. When this happens, you must check the equipment for dust and water droplets, so as to find the short-circuit point and troubleshoot it. If the value displayed by the meter is infinite, you need to replace the resistor body and weld the screws.
