Abstract
The operating temperature of a gas sensor capable of sensing a gas or a gas composition at a high temperature, for example 1000° C. is maintained constant over the entire volume of a gas sensor layer or function layer () secured to a sensor carrier section of the gas sensor by supplying heat to the gas sensor layer () in such a way that varying heat dissipations in the sensor carrier section are compensated. For this purpose, an electrical heater for heating the gas sensor layer () has individual heater sections with different heating resistance values which depend on a spacing between any individual heater section and the tip of the sensor carrier section.
