Method for operating sensor element for determining concentration of gas component in gas mixture from internal combustion engine of motor car, involves determining calibration parameter using adjusted value

摘要

The method involves connecting a sense element (112) and a pump cell (116) with pumping electrodes (120) with one another by solid electrolytes (118). A gaseous mixture (114) of an outer pumping electrode (122) is exposed and the gaseous mixture is separated from an inner pumping electrode (124) arranged in a cavity (128) by a porous diffusion barrier (126). The sense element is subjected with a defined concentration of the gas component, where calibration parameter i.e. sense element-specific property, is determined using an adjusted value. An independent claim is also included for a device for operating a sensor element for determining concentration of a gas component in a gas mixture.
