Abstract: A sensor element, in particular for detection of a physical property of a gas, in particular for detection of the concentration of a gas component or of the temperature or of a solid constituent or of a liquid constituent of an exhaust gas of an internal combustion engine, the sensor element including, a solid electrolyte film and including, located oppositely from one another in its longitudinal direction, first and second end regions, the sensor element including outside the second end region, in particular in the first end region, a functional element electrically conductively connected to a contact surface disposed in the second end region on the outer surface of the sensor element, the contact surface having a rounding, which is a radius, on its side facing away from the first end region. The contact surfaces each include three sub-regions: head region, neck region, and body region.

Abstract: The invention relates to an exhaust gas probe (120) for measuring properties of the exhaust gas of internal combustion engines, wherein at least one data storage unit (135) is arranged in a circuit associated with the probe, in particular arranged in a probe plug (130) or a connecting element associated therewith. The following properties and/or adaption functions characterizing the probe (120) are stored or storable in said data storage unit: —fluctuations of heating resistances that are due to the production process and/or—parameters that characterize the aging of the probe (120), and/or—the shut-off state, in particular data that characterize the execution of an interval measurement for regenerating the exhaust gas probe or of a delayed shut-off and/or—data for adapting the probe (120) to different control devices (140) of internal combustion engines and/or—the number of operating hours of the probe and/or—the operating parameters of the probe in a previous specifiable time period.

Abstract: A method for identifying sensors on a bus by a control unit, as well as a control unit and a sensor for doing this. The sensors, in this instance, send physical useful data to the control unit as the basis for the control of a function. Furthermore, the physical useful data are compared to one another and/or to specified expected values, and the identification of the sensors by the control unit takes place with the aid of the comparison and based on characteristic differences in the physical useful data for the sensors.
