摘要： A heat sensitive cable operable over a temperature range of between approximately -20.degree. F. and 1650.degree. F. The cable includes a tubular metallic sheath which is substantially temperature resistant and moisture impervious. It also includes a mass of compacted insulation material filling the sheath and having an insulation resistance variable with temperature in the range of between approximately 100 and 50,000 ohms. The cable further includes at least one thermoelectric conductor positioned within the insulation material filling the sheath. A method of manufacturing the cable includes the step of preparing the insulation material and advancing the thermoelectric conductor through a given region. It also includes the step of advancing a strip of flat metal material past apparatus for forming and welding a tubular sheath surrounding the given region. The method further includes the step of concurrently depositing the insulation material within the tubular sheath for enclosure and advancing the sheath, insulation material and conductor through apparatus for reducing the diameter of the sheath and applying tension to the conductor. With these steps, the insulation material is compacted and the conductor is positioned within the sheath.

摘要： 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.

摘要： A heat sensitive tape capable of generating a temperature representative measurable voltage. The tape includes an elongated flexible strip of electrically non-conductive material. A pair of thermoelectric conductors extend along the strip in spaced apart side-by-side relation. The tape also includes an electrical insulation capable of passively self-generating a temperature representative voltage between the conductors when the tape is exposed to ambient temperature. The insulation causes a change in the temperature representative measurable voltage with an increase or decrease in temperature at every location along the strip. A change in the temperature representative measurable voltage under such condition is representative of a change in ambient temperature. The 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 strip. With this arrangement, the heat sensitive tape may be utilized not only to monitor ambient temperature, but also to monitor for any localized increase in temperature.

摘要： A method of and apparatus and system for determining temperature conditions within an environment is disclosed. The method includes utilization of one or more transducers disposed within the environment. One or more of the transducers are selectively scanned to either intermittently or continuously monitor signals generated at any location along the transducers. Additionally, the method includes selectively identifying one or more of the scanned transducers which generate signals of interest and converting such signals into a sense perception signal indicative of a temperature of interest. The apparatus and system includes utilization of one or more transducers disposed within the environment. It also includes scanning means operatively associated with at least one transducer for sensing signals generated at any location along the transducers and which is capable of identifying one or more scanned transducers which generate signals of interest.
