Abstract
A method for detecting metal in an inner region of a caster mold during a casting process using a plurality of eddy current probe assemblies, wherein each of the plurality of eddy current probe assemblies is configured to generate a primary magnetic field passing through nonconductive mold material of the casting mold to the inner region of the casting mold and to provide a signal indicative of a detected secondary magnetic field caused by eddy currents induced in the metal.
