热电偶毫伏值与温度换算表
表Ⅳ-2-35 铂铑-铂(分度号LB-3)热电偶毫伏值与温度换算表
热电偶用补偿导线
热电偶用补偿导线的作用是来延伸热电极即移动热电偶的冷端，与显示仪表联接构成测温系统。本产品等效采用IEC584-3《热电偶第三部分—补偿导线》国家标准。绝缘层和所层选用进口优质氟塑料，并采用整体连续挤出新工艺，使该产品具有优良的耐酸、碱、耐磨和不燃延之性能，可浸入油水中长期使用。使用温度在-60~205~260℃属于当代国际先进水平。产品主要应用于各种测温装置，已被广泛用于石油、化工、冶金、电力等部门。
主要技术指标
补偿导线型号按产品的品种划分为：SC、KC、KX、EX、JX、TX。
其中：a）型号第一个字母与热电偶的分度号相对应；
b）字母“X”表示延伸型补偿导线（型别）
c）字母“C”表示补偿型补偿导线（型别）
(参考端温度为0℃)
