  • Abstract
    When thermocouples are exposed to radiofrequency fields, the unequal resistances of the two wires cause electrical currents to flow through the junction. The junction is thereby heated, resulting in erroneously high temperature readings. Experimental documentation for the effect and a theoretical explanation are presented. Methods to minimise the error are also suggested.
