Abstract:
A sensor element for an electrochemical sensor for determining oxygen content in exhaust gases of an internal combustion engine, comprising:at least one measuring electrode exposed to a measuring gas;at least one reference electrode exposed to a reference gas; andat least one heating device including a heating conductor and heating conductor leads, the heating conductor having at least two first heating circuit trace segments, each of the at least two first heating circuit trace segments being disposed outside a vertical projection of a reference gas channel, each of the at least two first heating circuit trace segments being conductively connected over the reference gas channel by a connecting segment having a larger circuit trace cross section than a cross section of each of the at least two first heating circuit trace segments, the connecting segment spanning the reference gas channel, the reference gas channel conveying the reference gas to the at least one reference electrode.
