IEC 60688:2021作为IEC 60688:2021 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60688:2021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流、模拟直流电压或数字形式。本文件适用于用于转换电量的测量传感器，例如-当前，-电压，-有功功率，-无功功率，-功率因数，-相位角，-频率，-谐波或总谐波失真，以及-表观功率输出信号。本文件不适用于-符合IEC 61869（所有部件）的互感器，-用于符合IEC 60770的工业过程应用的变送器（所有部件），以及-符合IEC 61557 12:2018的性能测量和监控设备(PMD)。在测量范围内，输出信号是被测物的函数。可能需要辅助电源。本文件适用a)如果输入的标称频率在0Hz和1500Hz之间，b)如果所述电测量换能器是用于测量非电量的系统的一部分，并且如果所述电测量换能器另外落入本文件的范围内，并且c)用于诸如遥测和过程控制等各种应用中以及用于许多限定环境之一中的传感器。本文件旨在:-规定与主要应用于工业的换能器相关的术语和定义，-统一用于评估换能器性能的测试方法，以及-规定传感器的精度限值和输出值。IEC 60688:2021取消并取代了2012年发布的第三版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)更新规范性参考文献；b)用于LV监测应用的特定传感器的附加要求；c)创建界面编码以方便最终用户的选择。

IEC 60688:2021 is available as IEC 60688:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60688:2021 applies to transducers with electrical inputs and outputs for making measurements of AC or DC electrical quantities. The output signal can be in the form of an analogue direct current, an analog direct voltage or in digital form.
This document 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 document is not applicable for
– instrument transformers that complies with IEC 61869 (all parts),
– transmitters for use in industrial process application that complies with IEC 60770 (all parts), and
– performance measuring and monitoring devices (PMD) that comply with IEC 61557 12:2018.
Within the measuring range, the output signal is a function of the measurand. An auxiliary supply can be needed.
This document applies
a) if the nominal frequency of the input(s) lies between 0 Hz and 1 500 Hz,
b) to the electrical measuring transducer if it is part of a system for the measurement of a non-electrical quantity, and if it otherwise falls within the scope of this document, and
c) to transducers for use in a variety of applications such as telemetry and process control and in one of a number of defined environments.
This document is intended:
– to specify the terminology and definitions relating to transducers whose main application is in industry,
– to unify the test methods used in evaluating transducer performance, and
– to specify accuracy limits and output values for transducers.
IEC 60688:2021 cancels and replaces the third edition published in 2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) updating normative references;
b) additional requirements for specific transducers used for LV monitoring applications;
c) creation of interface coding to ease selection by the end-user.
