Pt100 Thermal Resistance Temperature Sensor

Introduction

The Pt100 Thermal Resistance Temperature Sensor is an instrument that converts a temperature variable into a transmittable, standardized output signal. Mainly used for the measurement and control of industrial process temperature parameters.

Transmitters with sensors usually consist of two parts: the sensor and the signal converter. Sensors are mainly thermocouples or thermal resistances; signal converters are mainly composed of measuring units, signal processing, and conversion units (because industrial thermal resistances and thermocouple scales are standardized, signal converters are also called independent products. Transmitters), some transmitters add display unit, and some also have Fieldbus function.

Temperature is one of the physical parameters that humans interact with the most in nature. Whether it is in a production experiment site or in a residential and leisure place, the collection or control of temperature is very frequent and important. Moreover, the networked remote collection of temperature and alarm is modern technology. an inevitable trend of development. Since the temperature has a close relationship both with the physical quantity itself and in the actual people's lives, the temperature sensor will be generated accordingly.

Due to the relationship between the temperature and the resistance value of the PT100 thermal resistance, people took advantage of this feature to invent and produce the Pt100 Thermal Resistance Temperature Sensor. The temperature collection range can be -200℃～+850℃.

Installation method

If the pt100 temperature sensor consists of two sensors used to measure the temperature difference, there is a given continuous function relationship between the output signal and the temperature difference. There is a given continuous function relationship (usually a linear function) between the output signal of the pt100 temperature sensor and the temperature variable, and the output signal of the early production 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.

The temperature transmitter can be divided into a two-wire system and a four-wire system according to the power supply wiring mode. The transmitter has an electric unit combination instrument series (DDZ-Ⅱ type, DDZ-Ⅲ type, and DDZ-S type) and miniaturized modular type, 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 a thermocouple or thermal resistance to form a transmitter with a sensor.

The main advantage

①High measurement accuracy; the reason why the Pt100 Thermal Resistance Temperature Sensor has high measurement accuracy is mainly that the resistance temperature characteristics of some materials are stable and the repeatability is good. Second, compared with thermocouples, it has no reference junction error problem;

② have a larger measurement range, especially in low temperatures;

③Easy to use in automatic measurement and long-distance measurement.
