ABSTRACT:
A continuous strip sensor for detecting extremely cold temperatures is disclosed. The sensor includes a plurality of series connected sections each of which exhibits a substantial increase in resistance upon exposure to an extremely cold temperature. A detection circuit utilizing the above sensor provides compensation for changes in ambient temperature by means of a compensation-sensor having the same total resistance and resistance-temperature characteristic as the cold sensor. The detection circuit also detects the occurrence of faults in the cold sensor or the compensation-sensor.
