Anotace obsahu normy

This part of IEC 60730 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 or semiconductive substrate, for the detection of activating quantities such as voltage, current, temperature, pressure, humidity, light (e.g. optical), gasoline vapours, and the like.
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.
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.
