ABSTRACT:
A thermocouple device (A, B) and method having first and second thermoelectric elements for producing a Seebeck voltage effect for measuring high temperatures wherein the first thermoelectric element consists of a first graphite fiber strand, (10,24) and the second thermoelectric element consists of a second graphite fiber strand (12,26). The graphite fibers of the first and second strands and have different thermoelectric characteristics by virtue of different generic precursors and processes from which fibers are derived. In a preferred embodiment, the first graphite fibers are derived from a pitch precursor process, and the second graphite fibers are derived from a PAN precursor process.
