阻，配合信号平移、放大电路，利用片内A／D转换器，通过分时采样将热电阻对应的电压信号采集进来．
经过一阶插值拟合运算程序处理后显示温度值并由D／A转换器输出电压信号，再经过V-1变换实现
4—20 mA变送输出功能．-: Thermal resistance often used in industrial production in the low temperature zone temperature, the temperature measurement of more general use of temperature measurement devices. Through its temperature measurement principles of research, design microcontroller based MSP430FI69 thermal resistance thermometer. The design uses a constant current source driver RTD three-wire system, with the signal translation, amplification circuit, the use of on-chip A/D converter, sampling the thermal resistance through the time-corresponding voltage signal acquisition came. After fitting a first-order interpolation processing operation program displays the temperature value by D/A converter output voltage signal, and then transform through the V-1 4-20 mA transmitter output.
