SENSOR ELEMENT WITH INNER ANODE

摘要

The invention relates to a sensor element (210) for determining at least one physical property of a gas mixture in at least one gas chamber (212), wherein the element can be used as a lambda probe and/or in a lambda probe, for example. The sensor element (210) comprises at least one first electrode (218; 219), at least one second electrode (216; 215) and at least one solid electrolyte (214) connecting the at least one first electrode (218; 219) and the at least one second electrode (216; 215). The at least one first electrode (218; 219) and the at least one second electrode (216; 215) are arranged within the sensor element (210). The at least one second electrode (216; 215) is connected to at least one reference gas chamber (242) via at least one exhaust air duct (240).
