热电偶时间常数的一例实时求解方法

A real-time solution for time-constant of thermoelement

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 ,较准确地求解出热电偶使用时刻的时间常数 ;并利用相关算法 ,可较大幅度地减小测量的动态误差 。

Base on response characteristics of the thermoelement, with the temperature data of sampling point and algorithm of real time on line data processing,the authors worked out thermoelement time constant at testing moment. It can reduce not only the dynamic error of measurement with related algorithm,but the measuring time.
