ABSTRACT:
A heat sensitive cable capable of generating a temperature representative measurable voltage. The cable includes a pair of thermoelectric conductors disposed in contacting side-by-side relation together with an electrical insulation for passively self-generating a temperature representative measurable voltage between the conductors when the cable is exposed to ambient temperature. A flexible outer jacket formed of an electrically non-conductive material is provided to completely surround the conductors. The electrical insulation causes a change in the temperature representative measurable voltage with an increase or decrease in temperature at every location along the jacket. A change in the temperature representative measurable voltage under such condition is representative of a change in ambient temperature. The electrical insulation also causes a change in the temperature representative measurable voltage with an increase in temperature above the prevailing ambient at any location along the jacket. With this arrangement, the heat sensitive cable may be utilized not only to monitor ambient temperature but also to monitor for any localized increase in temperature.
