ABSTRACT:
A method of producing a multiple thermocouple having a conductive open-cellular foam matrix, a portion of which forms a first pole with a plurality of discrete conductors of a different material from the foam matrix embedded in the foam having a portion of each of the discrete conductors being exposed on the insides of the cells of the foam forming a plurality of thermocouples. The remaining surface area inside the foam's cells not having an exposed discrete conductor thereon can be insulated. A second pole member is provided. Means to contact the discrete conductors in the foam and convey current produced by the thermocouples to the second pole of the thermocouple completes the multiple thermocouple. Such means to contact the discrete conductors can provide the heat to excite the thermocouples or such heat can come from other sources.
