Temperature is a basic physical quantity, and all processes in nature are closely related to temperature. Temperature sensor is a kind of sensor developed earlier and widely used. The market share of temperature sensor is much more than other sensors.

The main types of temperature sensors are as follows:

1、 Thermocouple sensor has its own advantages and disadvantages. The metal material of thermocouple has good ductility. This kind of tiny temperature measuring element has high response speed and can measure the process of rapid change. However, the sensitivity of thermocouple sensor is relatively low, and it is easy to be affected by environmental interference signals, so it is not suitable for measuring small temperature changes.

2、 Thermistor has high sensitivity and small volume. Its temperature coefficient of resistance is 10-100 times larger than that of metal. It can detect the temperature change of 10-6 ℃; The normal temperature device is suitable for - 55 ℃ ~ 315 ℃, and it has a wide working temperature range and a wide measurement range. It can measure the gap that other sensors can't measure, and has strong shaping ability, which can better meet the customer's customized requirements.
