Abstract (en)

[origin: EP0442275A2] The pot detection system operates with an inductive sensor (22) which is arranged close to the heated region of the cooking apparatus (11). The sensor signals are evaluated as a function of the signal rate of change in order to compensate for the poor coil quality of the high-temperature-resistant coils. The evaluation takes place digitally with frequency counting, and a bridging device (50) is provided in order to be able to use the apparatus even without pot detection. <IMAGE>
