So the pot detection from 10 MHz to 17 MHz, preferably from 11 MHz to 15 MHz and particularly preferably from 12.5 MHz to 13.5 MHz and the temperature measurement at 150 Hz to 600 Hz, preferably from 200 Hz to 400 Hz and particularly preferred operated from 250 Hz to 350 Hz. Also sequential query of the two Measured variables are possible.
- the conductor track area for the temperature measurement in the middle of the cooking zone carries not to the signals of the pot detection in the specified embodiment because the electrode coming from the outer circle is not a loop is executed and is therefore not flowed through by the current. It is therefore not inductively effective.
