标准摘要
[中文适用范围]： IEC 60730-2-23:2025 适用于电气、机电及电子式传感器（包括传感元件及其相关信号调理电路）的安全性能。本文件所涵盖的传感器仅用于将输入激活量转换为可用输出信号，并不执行 IEC 60730-1 中定义的控制操作。本文件适用于定义传感器自身特性及其在正常与异常工况下响应特性的可靠性与准确性。文中所定义的传感器，可用于自动电气控制系统中，或作为与控制系统配套的独立安装器件。在确保最终产品标准所规定的安全要求得到满足的前提下，本文件亦适用于传感器在其他应用场景中的使用。本文件适用于以导电材料、半导体材料或基板等材料构成的分立式传感器，用于检测诸如电压、电流、温度、压力、湿度、光（例如光学）、汽油蒸气等激活量。注 1：未来将考虑其他材料（如化学材料、机械结构及微机电系统 MEMS 等）构成的传感器技术，以及质量流量、液体、运动、重量、振动等其他激活量。本文件适用于传感器内部的传感元件、电子硬件、软件或其他信号调理电路，这些部分对于将输入信号可靠转换为满足功能安全要求的输出信号至关重要。若信号调理电路与控制系统不可分割，且传感元件依赖该电路实现其预定功能，则其评估应依据相关控制系统标准第 2 部分或 IEC 60730-1 的要求。注 2：传感器所在应用标准中亦可提出额外要求。全文中，凡注明适用 IEC 60730-1 要求的场合，除非另有说明，均将术语“控制器”替换为“传感器”，“设备”替换为“控制系统”，以符合 IEC 60730-1 中的术语使用方式。本文件不适用于 IEC 60730 系列其他第 2 部分中已明确规定的其他传感器，例如 IEC 60730-2-5 中所述的火焰传感器。注 3 [外文原描述]： 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.
