Fire or overheating detection system

摘要

A system for detecting fire or overheating includes a sensor (C) including at least one material having a resistance with a selected temperature coefficient, wherein the resistance of the material is indicative of a temperature. The system includes further a device (T) connected to the sensor (C) to perform measurements on the material, wherein the device (T) is configured to determine at least one parameter from the measurements and to analyze a dynamic behaviour of the at least one parameter to deduce status information including overheating and malfunction of the sensor (C). <IMAGE>
