pt100 temperature sensor is an instrument that converts temperature variables into standardized output signals that can be transmitted. It is mainly used for measurement and control of industrial process temperature parameters. The transmitter with sensor usually consists of two parts: the sensor and the signal converter. The sensor is mainly a thermocouple or thermal resistance; the signal converter is mainly composed of a measurement unit, a signal processing and conversion unit (since industrial thermal resistance and thermocouple graduation tables are standardized, the signal converter is also called a transmitter when it is an independent product), some transmitters have a display unit, and some have fieldbus functions.
