将交流和直流电量转换成模拟信号或数字信号用的电测量变送器

[中文适用范围]： 本国际标准适用于具有电气输入和输出的传感器，用于测量交流或直流电量。输出信号可以是模拟直流电压、模拟直流电压的形式或数字形式。在这种情况下，用于通信目的的传感器部分将需要与外部系统兼容。本标准适用于用于转换如下电量的测量传感器： ?C 电流@ ?C 电压@ ?C 有功功率@ ?C 无功功率@ ?C 功率因数@ ?C 相位角@ ?C 频率@ ?C谐波或总谐波失真@ ?C 输出信号的视在功率。本标准不适用于： 符合IEC 60044系列的C级互感器； ?C 变送器用于符合 IEC 60770 系列的工业过程应用；符合 IEC 61557-12 的 C 性能测量和监控设备 (PMD)。在测量范围内，输出信号是被测量的函数。可能需要辅助电源。本标准适用于： a) 如果输入的标称频率位于 0 Hz 至 1 500 Hz 之间； b) 如果测量传感器是非电量测量系统的一部分，则本标准可适用于电气测量传感器，如果它属于本标准的范围； c) 用于各种应用的传感器，例如遥测和过程控制以及许多定义的环境之一。本国际标准的目的是： ?C 规定与主要应用在工业中的传感器相关的术语和定义； ?C 统一评估换能器性能的测试方法； ?C 指定传感器的精度限制和输出值。 [外文原描述]： IEC 60688:2012 applies to transducers with electrical inputs and outputs for making measurements of a.c. or d.c. electrical quantities. This International Standard is intended to specify the terminology and definitions relating to transducers whose main application are in industry; to unify the test methods used in evaluating transducer performance; and to specify accuracy limits and output values for transducers. The output signal may be in the form of an analogue direct current, an analogue direct voltage or in digital form. In this case, that part of the transducer utilized for communication purposes will need to be compatible with the external system. This standard applies to measuring transducers used for converting electrical quantities such as current, voltage, active power, reactive power, power factor, phase angle, frequency, harmonics or total harmonic distortion, and apparent power to an output signal. This standard is not applicable for instrument transformers that comply with IEC 60044 series; transmitters for use in industrial process applications that comply with the IEC 60770 series; performance measuring and monitoring devices (PMD) that comply with IEC 61557-12.
