SENSOR ELEMENT HAVING A PRINTED CONDUCTOR AND A REFERENCE GAS DUCT

摘要

A sensor element for detecting a physical property of a gas includes: a solid electrolyte film; a first end area and a second end area situated diametrically opposite in the longitudinal direction; a functional element in the first end area in the interior which is electrically conductively connected to a contact surface situated in the second end area on the outer surface, the electrically conductive connection having a strip conductor running essentially in the longitudinal direction in the interior of the sensor element; and a reference gas channel running essentially in the longitudinal direction of the sensor element communicating with a reference gas outside of the sensor element via a reference gas opening, the strip conductor and the reference gas channel being situated in such a way that at least a partial overlap occurs between them.
