HEAT-SENSITIVE PICK-UP CABLE Russian patent published in 2016 - IPC H01B7/16 

FIELD: fire safety.

SUBSTANCE: invention relates to fire alarm equipment and can be used in fire alarm systems in aircraft, chemical reactors, industrial enterprises, and represents heat-sensitive pick-up cable having coaxial metal shells (1) and conductor electrodes (3, 4, 5) with gaps, separated by semiconductor filler (2) with negative temperature coefficient of electric resistance, wherein conductor electrodes elements are made of metals and/or alloys with different electrons energy, in pairs forming thermocouples in pick-up cable specific points and which are sources of thermo-EMF additional signals in accident heating.

EFFECT: invention enables extending controlled temperatures range, including in accident heating (fire) process and pick-up cable functional capabilities, determination of heating zone with simultaneous control over temperature and duplication of signals in case of fire, which is necessary in aircraft fire fighting systems.
