If temperature detection is required, you need to choose the appropriateTemperature Sensor，Temperature SensorAfter sensing the temperature, it can be converted into a sensor that can output a signal. Thermocouples and thermistors are commonly used in testing.Temperature Sensor, the principles are different and each has its own characteristics.

Thermocouples are commonly used temperature sensors with a wide temperature range, adaptability to various atmospheric environments, durability, no need for power supply, and lower cost. However, due to the nonlinear relationship between voltage and temperature, there will be deviations in some high-precision measurements and applications, so they are not very suitable, but they are more than enough for simple tests. Another point is also the characteristic of thermocouple temperature sensors, because its sensitivity has nothing to do with the thickness of the material, so it can be made of very fine materials.

Thermistors use semiconductor materials and their resistance changes with temperature to achieve the function of temperature sensors. They are small in size, sensitive to temperature changes, and suitable for current sources. They have higher accuracy than thermocouples, but their test temperature range is narrow. They are also not durable and their cost is higher.

The two resistors have their own advantages and disadvantages, so when choosing, we need to choose the appropriate temperature sensor according to the needs.
