6、⋯⋯20GB/'r13850-1998前言本国家标准等同采用国际标准IEC688《交流电量转换为模拟量或数字信号的电工测量变送器》(第二版1992年)及其1997年第1号修订。本标准将代替GB/丁13850.1^-13850.2-92(交流电量变换为直流电量的电测量亦送器》。本标准与原国家标准GB/T13850.1^-13850.2-92相比具有以下特点:1)分类合理，将变送器分为三个使用组别，变送器的参比条件、标称使用范围与使用组别有关，便于用户选型;2)大幅度放宽了温度的参比范围，其中I组:20'C,230C、或27℃士I'C;I组:15-30'C;19组:。~45'C。而在原国家标准中，

7、温度的参比范围分别为:20'C.230C、或27℃士11x(0.1-0.5级)和士2'C(1^2.5级).这一改变提高了变送器的性能;3)简化了变送器模拟输出信号(电压、电流)的可选值，规定4mA-20mA是优选值，增加了数字信号输出;4)对功率因数引起的改变量做了明确规定;5)增加了温升试验;6)对于GB/T13850中一些“由用户与厂家协商”的技术要求做出了明确规定;7)加入对IEC688第1
