摘　　要：介绍一种用AT89C5 1单片机控制 ,使用铂热电阻温度传感器 ,具有自动校零、自检、报警、显示、多路温度巡测功能的系统 .实践证明该系统性能稳定 ,抗干扰能力强 。A temperature control instrament with platinum resistance sensor for dry_type transformers, a multi_path temperature detecting_measarement system, which is controlled by a single_chip micro_processer AT89C51 and has function of auto_correction zeropoint, self_verifying, alarm and display; is described. The practice shows that the system has following advantages:stable in its performance, stronger in its anti_interference ability and higher in its measurement precision.
