本文分析了热电偶的动态误差,介绍了常用的校正方法,根据各自的不足之处,提出了一种基于微机处理的动态误差校正方法,该方法既能缩短测温时间又可以方便地在线实时求解时间常数,基本实现温度的实时检测。关键字:动态误差 传递函数响应特性热电偶Abstract: Analyzed the dynamic error of thermocouple, introduced common correction method. On the basis of its no perfection, gave a correction method for dynamic error base on processing of microcomputer. With the method, the time of measurement is contracted and we can determined the time-constant with the real-time data, and realized real-time measurement of temperature.Keywords:Dynamic-error Transfer-function Response-characteristic Thermocouple
