Abstract
A method and apparatus for measuring the temperature and heating rate of a workpiece during the induction heating cycle by inducing and detecting a plurality of eddy current pulses at varying frequencies during a short power interruption to the induction coil and correlating the pulses to generate a workpiece profile which is compared to a reference profile to determine whether to reject the inductively heated workpiece.
