HEATING DEVICE FOR HEATING FLUIDS, AND METHOD FOR OPERATING A HEATING DEVICE OF THIS KIND
First Claim
1. A heating device for heating fluids, comprising:
- a flat support with a surface;
a plurality of heating elements being arranged distributed over said entire surface of said flat support;
said heating elements being divided into one or more heating circuits;
said one or more heating circuits are operable separately from one another;
a temperature sensor device with a sensor layer covering at least a surface area of said heating elements;
at least two sensor electrodes in an electrode layer being fitted onto said sensor layer;
said two sensor electrodes being electrically disconnected from one another and having finger-like or turn-like sensor electrode sections which run at a distance of less than 2 cm in relation to one another;
a width of in each case two said sensor electrode sections being arranged next to one another is less than 2 cm in each case; and
a control apparatus for evaluating said temperature sensor device.

Abstract
A heating device for heating fluids has a flat support with a surface on which heating elements are arranged distributed over the surface area and are divided into one or more heating circuits which can be operated separately from one another. A temperature sensor device is provided with a sensor layer which covers the surface area of the heating elements. At least two sensor electrodes in an electrode layer are fitted onto the sensor layer, the at least two sensor electrodes being electrically disconnected from one another and having finger-like or turn-like sensor electrode sections which run at a distance of less than 2 cm in relation to one another. The width of in each case two sensor electrode sections which are arranged next to one another is less than 2 cm in each case. A control apparatus for evaluating the temperature sensor device is provided.
