ABSTRACT:
Disclosed is a fire detection and engine monitoring system of the type which utilizes a pair of elongated thermistor strands extending over substantially the same path to provide redundancy. A resistance of the two thermistor strands are sensed and a resistance difference signal is generated. The resistance signal is monitored for abnormal differences between the two identical thermistor devices which are essentially exposed to the same operation conditions. Such differences are indicative of the deterioration over time of the condition of one of the sensors.
