Abstract

A sensor positioned between a heat source and a heating area in parallel relationship to the heating area, for determining a mean value of the temperature of the heating area, includes a ceramic element, and a temperature-dependent resistor web attached to the ceramic element and confronting the heating area at a distance thereto. The resistor web has a length of at least 200 mm, and is electrically contacted at a contact point outside a region in which the temperature is to be ascertained.
