摘要
介绍了一种利用铂电阻作为温度传感器 ,测温范围在 0～ 2 0 0℃ ,输出电压范围在 0～2V的具有较高精度和分辨率的线性多点测温系统的设计方案 ,并通过多路 /分时模拟量输入通道将测温电路输出的多路信号依次循环输入计算机 。
A system of linear multi-point temperature-measuring is introduced,which is devised by taking advantage of Platinum-made temperature-measuring to the temperature within 0 to 200℃,The rang of output voltage is between 0 to 2V correspondingly and possesses rather high precision and resolution.By using the multi-route/time-sharing analog input-channel,signals are input a computer successively.As a result,the furnace temperature can be measured real time.
