Abstract:
A length of metallic wire is positioned inside a length of metallic tube in approximate axial alignment with the tube. A short sleeve is placed around the end of the wire. The sleeve is a different metal from the tube. The difference between the thermoelectric coefficients of the sleeve metal and the wire metal is larger than the difference between the thermoelectric coefficients of the tube metal and the wire metal. The tube metal is more resistant of oxidation than the sleeve metal.
