Abstract

A sensor apparatus includes a first electrode and a second electrode at a predefined distance from one another. The sensor apparatus includes a substrate arranged in a predefined first region of the sensor carrier such that the first electrode and the second electrode are substantially electrically decoupled from one another if the outer side of the sensor carrier is substantially free of particles. A third electrode is coupled to a solid electrolyte that is additionally coupled to the second electrode. A diffusion barrier is coupled to the third electrode in a predefined third region and the exhaust gas is applied to the third electrode only in the third region via the diffusion barrier.
