Energization cycle counter for induction heating tool

An induction heat treating process with a remote sensor for monitoring the duration of energization of an induction heating coil each time the induction heating coil is consecutively cycled. An identifying tag is preferably attached to, embedded within the induction heating coil or within the surrounding area of the induction coil and transmits a signal to a remote counting sensor that is preferably triggered by and responds to the change in voltage generated as the coil is energized. Alternative means of measuring a cycle may be implemented. The output data from the sensor provides useful information for determining the lifespan of an induction heating coil. Predicting the lifespan of a coil optimizes production by anticipating failure and replacement of a coil during a predetermined down time, limiting on-site inventory, and revolutionizing the billing cycle based on a per cycle cost while decreasing overall production costs and improving inductor coil quality.
