Abstract:
1. An induction heating system, comprising: An induction heating power source; a controller configured to control output of the induction heating power source based on a plurality of signals representative of work piece temperatures at a generally common time of induction heating at a portion of a work piece, wherein the controller is operable to select an outlier signal from the plurality of signals representative of work piece temperatures to control the output of the induction heating power source based on a programmed control scheme, wherein the controller comprises a processor operable to receive programming instructions and the plurality of signals representative of work piece temperature from each of a respective one of a plurality of temperature feedback devices, wherein the processor is configured to select one of the plurality of temperature feedback devices to control the induction heating power source based on the signal from the selected temperature feedback device and the programming instructions; and an interface adapted to enable the plurality of temperature feedback devices to be communicatively coupled to the processor, wherein the interface comprises a plurality of analog-to-digital converters configured to convert each of the signals representative of work piece temperatures to a digital signal representative of work piece temperature.
