There are many kinds of temperature sensors, which use thermocouple and resistance.
Among the commonly used thermal resistances, the measurement accuracy of platinum thermal resistance is the highest, and it has a very stable resistance temperature relationship.
Compared with thermocouple, it has the following advantages:
1 The accuracy is high, and the error of temperature sensor is the least
2 Large measurement range
3 The fluctuation is relatively small. When the temperature fluctuation is small, it can achieve the accuracy and repeatability of 0.1 ℃.
