摘要
热电偶是常见的检测元件,但热电势与温度呈非线性关系,因而需要线性化。本文提出了用软件对热电偶进行温度补偿的一种简单方法——折线拟合法,并详细介绍了此方法的程序设计及查表处理。
The thermocouple is a common detedtion element which records the non-linear relation between thermal emf and temperature and needs linearization. A software——Broken Line Curve Fitting——is introduced as a convenient means of temperature compensation for the thermocouple. Details for the curve-fitting program and table look up are included.
