A monitor device for creating a current signal having a voltage representative of the instantaneous alternating current in an induction heating coil connected to an alternating current supply by two closely spaced, parallel input conductors separated by a narrow gap or flux package through which flows the flux created by the alternating current in the parallel conductors. The monitor device comprising: a multiturn sensing winding, means for securing the winding between said parallel conductors and over the flux passage whereby the flux flowing through flux passage intersects the turns of the sensing winding, and means for creating the current signal by the induced voltage in the winding.
