[中文适用范围]： IEC 60730-2-23:2025 EXV 包含国际标准及其扩展版本 (EXV)。此官方 IEC 标准的扩展版本仅提供英文版，为用户提供标准的全面内容。IEC 60730-2-23:2025 EXV 包含对 IEC 60730-1:2022 的引用内容。IEC 60730-2-23:2025 适用于电气、机电和电子传感器（包括传感元件和任何调理电路）的安全。本文件涵盖的传感器仅用于将激活量转换为可用输出，不执行 IEC 60730-1 中定义的控制操作。本文件适用于定义传感器固有工作特性的可靠性和准确性以及传感器在正常和异常条件下的相应响应的传感器。本文定义的传感器用于自动电气控制系统中或作为其一部分，或作为与控制系统连接的独立安装设备。只要符合最终产品标准规定的适当安全性，本文件也可应用于其他使用传感器的应用。本文件适用于由（但不限于）导电材料、半导体材料或基材构成的离散传感器，用于检测电压、电流、温度、压力、湿度、光（例如光学）、汽油蒸汽等触发量。注1：未来将考虑采用其他材料（例如化学、机械和微机电系统 (MEMS)）构成的传感器技术，以及其他触发量，例如质量流量、液体、运动、重量、振动或其他（根据需要）触发量。本文件适用于传感元件以及传感器固有的任何电子硬件、软件或其他调理电路，这些电路用于将输入信号可靠地转换为可用于功能安全的响应信号（输出）。与传感元件执行其预期功能的控制器不可分割的调节电路，应根据相关控制器第2部分标准和/或IEC 60730-1的要求进行评估。注2：传感器的应用标准也可能适用其他要求。在本文件中，除非另有规定，否则凡指明适用IEC 60730-1要求时，“控制器”一词均由“传感器”一词替代，“设备”一词由“控制器”一词替代，与IEC 60730-1中的用法相同。本文件不适用于IEC 60730系列其他相关第2部分中明确描述的传感器。注3：例如，IEC 60730-2-5中描述的火焰传感器。 [外文原描述]： IEC 60730-2-23:2025 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 60730-2-23:2025 EXV includes the content of the references made to IEC 60730-1:2022. IEC 60730-2-23:2025 applies to the safety of electrical, electro-mechanical and electronic sensors including sensing elements and any conditioning circuitry. Sensors covered under the scope of this document serve only to transform an activating quantity into a usable output and do not perform a control operation as defined in IEC 60730-1. This document applies to sensors in so far as defining the reliability and accuracy of their inherent operating characteristics and corresponding response under normal and abnormal conditions within the sensor. Sensors, as defined herein, are used in or as part of an automatic electrical control or as independently mounted devices in connection with controls and control systems. The use of this document for other applications in which sensors are used is possible provided that the appropriate safety is maintained as defined by the end product standard. This document applies to discrete sensors constructed of, but not limited to, conductive, semi-conductive, or substrate, for the detection of activating quantities such as voltage, current, temperature, pressure, humidity, light (e.g. optical), gasoline vapours, and the like. NOTE 1 Future consideration will be given to other sensor technologies constructed of other materials such as chemical, mechanical and micro-electromechanical systems (MEMS), along with other activating quantities like mass flow, liquid, movement, weight, vibration, or other as needed. This document applies to sensing element(s) as well as any electronic hardware, software, or other conditioning circuits that are inherent to the sensor and relied upon to reliably transform the input signal into a useable response signal (output) for functional safety purposes. Conditioning circuits that are inseparable from the control for which the sensing element relies upon to perform its desired function are evaluated by the requirements of the relevant control Part 2 standard and/or IEC 60730-1. NOTE 2 Additional requirements can be also applied by the application standard in which the sensor is used. Throughout this document, whenever it is indicated that the IEC 60730-1 requirements are applicable, the term "control(s)", is replaced by the term "sensor(s)", and the term "equipment" is replaced by the term "control", as they are used in IEC 60730-1, respectively, unless otherwise specified herein. This document does not apply to sensors explicitly described in another relevant part 2 of the IEC 60730 series. NOTE 3 For example, a flame sensor as described in IEC 60730-2-5.
