Abstract

A sensor element, which may be used as Lambda probe and/or inside a Lambda probe, for example, is provided for determining at least one physical property of a gas mixture in at least one gas chamber. The sensor element has at least one first electrode, at least one second electrode and at least one solid state electrolyte, which connects the at least one first electrode and the at least one second electrode. The at least one first electrode and the at least one second electrode are situated inside the sensor element. The at least one second electrode is connected to at least one reference gas chamber via at least one discharge air channel.
