Abstract

A sensor element is provided for gas sensors, in particular to determine particles in gas mixtures, the sensor element including at least one electrochemical measuring element exposed to the gas mixture to be determined, and at least one temperature-measuring element integrated into the sensor element. The temperature-measuring element includes a resistor track, which has an electric resistance of less than 180 Ohm at 0° C. The resistor track may thus be produced by thin-foil technology, such as screen printing, for example.
