A Temperature Measurement System Based on PT100
Jiguang Liu, Yukun Li, Hongyan Zhao · 2010
Temperature measurement system is mainly constituted by the Micro Controller Unit (MCU), the temperature sensor and the analog digital converter (ADC). The model of the MCU is STC10F12. The model of the ADC is AD7711, and the AD7711 can carry out the signal conditioning and analog digital (AD) conversion. It also can provide the constant current source for PT100. This temperature measurement system has many features, such as high accuracy, small size, micro-power, anti-interference ability.
