摘要
提出了对热电偶低温段非线性校正的一种新方法,通过对热电阻进行变换,取出电压信号,经过匹配参数及零点迁移后,将热电偶的凹曲线与热电阻的凸曲线合成、迭加,曲线被校直,效果颇佳。
This paper gives a new method of nonlinearity calibration of thermocouple. By changing the ther-moresistance R - t characteristic. the voltage signals are taken out, then the R - S curve is rnoved down.These E-t curves and R - t curves are added. The result is very good.
