What are the structure types of thermal resistance? How to choose the thermal resistance of different materials?

In different environments, if you want to measure the temperature in the environment, you need to use professional equipment. Moreover, everyone has to choose the corresponding equipment according to different environments, so as to measure the temperature in the environment. Thermal resistance is a commonly used temperature measurement device. So, what are the structure types of thermal resistance? How to choose the thermal resistance of different materials? 1. Common structure types When buying thermal resistance equipment, you usually encounter two types of thermal resistances, one is wire wound element type, and the other is thin film element type. These two RTDs can measure the temperature of different environments. Among them, the common wire wound element type electric heating group and the thin 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 the appropriate measurement equipment according to the needs of the measurement environment. two. Characteristics of different materials Although the thermal resistance of ceramic material can be applied to very low and high temperature, its anti-vibration ability is not very high; in addition to the advantages of thermal shock, glass material also has strong anti-vibration ability. In addition, the silicon wafer material is suitable for thin film thermal resistance equipment. 3. Common fault handling methods When using thermal resistance equipment, you can often see that the displayed value of the instrument is lower than the actual value or unstable. In this case, you must check the equipment for dust and water droplets, so as to find the short-circuit point and conduct an investigation. If the meter shows an infinite value, you need to replace the resistor body and weld the screws. Understanding the common faults of thermal resistance and how to deal with them can help everyone use this equipment better. Correct use of thermal resistance can obtain more accurate data, ensure the correct value, and ensure the experimental effect.
