摘要： Temperature sensors or temperature sensor arrangements made from glass ceramic and bonding film resistors, suitable especially for control and limitation of output in glass ceramic cooking areas, are distinguished in that thin- and/or thick-film resistors are baked on supports of glass ceramic, for example, in the area of the cooking zone of a glass ceramic cooking surface, and one or more glass ceramic resistances are delimited and bonded there, and the film resistors form parallel and/or iterative circuits with the glass ceramic resistances. By suitable selection of the dimensions as well as the surface resistances and temperature coefficients of the bonding film resistors and the type of sensor circuit (parallel and/or iterative circuit), the temperature resistance characteristic of a sensor circuit can be varied within wide limits, e.g., the temperature area of use of a glass ceramic sensor can be considerably expanded toward low temperatures. The geometric shape of a sensor arrangement can be matched to the specified temperature distribution of a surface to be monitored, for example, a glass ceramic cooking surface in the area of the cooking zones, so that practically all areas of the heated surface essential for the temperature control and limitation are detected.
