基于实时时间常数的热电偶动态误差校正

摘要

根据热电偶的响应特性，利用采样点的温度数据，采用在线式实时处理算法，能较准确地求解出热电偶使用时刻的时间常数。而且利用相关的算法，可较大幅度的减小测量的动态误差，并且缩短测量时间。%Base on response characteristic of the thermocouple, with the temperature data of sampling point and algorithm of real-time-on-line data processing,can evaluation time-constant of thermocouple's usage-time.It not only reducing　dynamic-error of measurement with related algorithm，but contraction time of measurement.
