Induction heating plate

The invention relates to an induction heating device providing a support plate with an upper surface for receiving a side face of a bearing. A plurality of concentrically arranged induction coils provided at an underside of the support plate, and connected to and selectively powered by a generator. Temperature sensors arranged on the upper surface of the support plate at different radial distancesfrom a center axis of the concentric coils, so each coil is associated with at least one temperature sensor that overlaps or is radially in close proximity to the coil. A control unit receives and monitors a temperature signal from each of the temperature sensors, which receives and processes a signal indicative of a load on each coil, when selectively powered, to identify a first coil and a second coil that are electromagnetically coupled to an inner ring and an outer ring of the bearing. The control unit configured to select a first and a second temperature sensor associated with the firstand second coils respectiv
