Abstract
A hot-wire anemometer includes a graphite fiber hot wire forming one arm of a resistance bridge. Graphite fibers have high tensile strengths, relatively high temperature coefficients of resistance and other thermal and electrical properties which make them particularly suitable for use as anemometer hot wires. The graphite fibers may be doped or intercalated with chemical species that adjust their thermal and electrical properties.
