说明：  温度传感器（temperature transducer）是指能感受温度并转换成可用输出信号的传感器。温度传感器是温度测量仪表的核心部分，品种繁多。按测量方式可分为接触式和非接触式两大类，按照传感器材料及电子元件特性分为热电阻和热电偶两类。
(A temperature sensor is a sensor that can sense the temperature and change it to a usable output signal. Temperature sensor is the core part of temperature measuring instrument. It can be divided into two types: contact type and non-contact type. According to the characteristics of sensor materials and electronic components, they are divided into two types: thermal resistance and thermocouple.)
