Abstract
The invention relates to a method for determining and regulating the temperature of an article with inductive properties which is heated inductively by means of an induction device, wherein the induction device contains an induction coil, means for producing an induction resonant circuit and a support element arranged above the induction coil and having a first side, which acts as support face for the article, and a second side, which is directed towards the inductive coil. At least one temperature sensor is fitted to the second side. The resonant frequency of the induction resonant circuit is measured via detection means and the temperature of the article is calculated from the measured resonant frequency, wherein the resonant frequency is related to the temperature of the article by virtue of a mathematical function, and the function is determined by determining at least two absolute temperature calibration values of the article at respectively different resonant frequencies. The temperature calibration values are calculated from temperature measured values of the sensor.
