PT100 thermal resistance temperature sensor

The PT100 temperature sensor is an instrument that converts temperature variables into a transmittable standardized output signal. Mainly used for measurement and control of temperature parameters in industrial processes. A transmitter with a sensor usually consists of two parts: the sensor and the signal converter. The sensor is mainly a thermocouple or a thermal resistor; the signal converter is mainly composed of a measuring unit, a signal processing and a conversion unit (since industrial thermal resistors and thermocouple scales are standardized, the signal converter is also called Transmitter), some transmitters have added display units, and some also have fieldbus functions.

　　Temperature is one of the physical parameters that interacts most with humans in nature. Whether in production and experimental sites or residential and leisure sites, temperature collection or control is very frequent and important. Moreover, networked remote temperature collection and alarm are modern technologies. an inevitable trend of development. Since temperature is closely related to both the physical quantity itself and actual people's lives, temperature sensors will be produced accordingly. Due to the relationship between temperature and resistance change of PT100 thermal resistor, people took advantage of this characteristic to invent and produce PT100 thermal resistor temperature sensor. It is an intelligent sensor integrating temperature and humidity collection. The temperature collection range can be from -200℃ to +200℃, and the humidity collection range is from 0% to 100%.

　　If the PT100 temperature sensor is composed of two sensors used to measure the temperature difference, there is a given continuous functional relationship between the output signal and the temperature difference. Therefore it is called. There is a given continuous functional relationship (usually a linear function) between the output signal of the pt100 temperature sensor and the temperature variable. The output signal of the early produced pt100 temperature sensor has a linear functional relationship with the resistance value (or voltage value) of the temperature sensor. . The standardized output signals are mainly DC signals of 0mA~10mA and 4mA~20mA (or 1V~5V). Other standardized output signals with special provisions are not excluded. Temperature transmitters can be divided into two-wire systems and four-wire systems according to the power supply wiring method. The transmitters include electric unit combination instrument series, small modular type, and multi-functional intelligent type. The former does not have a pt100 temperature sensor, and the latter two types of transmitters can be easily combined with thermocouples or thermal resistors to form a sensor-equipped transmitter.
