How to distinguish between thermocouple and thermal resistance1

The difference between thermocouple and thermal resistance is: 1. The principle of temperature measurement is different: the principle of temperature measurement of thermocouple is based on the thermoelectric effect. The temperature measurement principle of the thermal resistance is different from the temperature measurement principle of the thermocouple in that the thermal resistance is based on the thermal effect of the resistance for temperature measurement, that is, the resistance of the resistor changes with the temperature. Therefore, as long as the resistance change of the thermal resistance is measured, the temperature can be measured. 2. Different structures: There are two types of thermocouples, common type and armored type. Ordinary thermocouples are generally composed of thermode, insulating tube, protective sleeve and junction box, while armored thermocouple is a combination of thermocouple wire, insulating material and metal protective sleeve. A solid combination formed by stretching. 3. Compensation wires are different: Different thermocouples need different compensation wires. Its main function is to connect with the thermocouple to keep the reference end of the thermocouple away from the power supply, so that the temperature of the reference end is stable. The thermal resistance is the same as the thermocouple, but it does not require a compensation wire, and it is cheaper than the thermocouple.

Currently there is a global trend growing. People are more conscious about RTD supplier and are seeking alternatives to traditional solutions.
