ポンプセルを含む固体電解質センサ素子を動作させるための方法

摘要

A method is described for operating a sensor element for detecting at least one concentration of a gas in a measuring gas chamber. The sensor element includes at least one pump cell having at least two pump electrodes connected to each other by at least one solid electrolyte. At least one measuring variable is detected in the method, and at least one compensating variable is determined. The compensating variable is at least partially dependent on capacitive effects on at least one junction between at least one of pump electrodes and the solid electrolyte. At least one corrected measuring variable is determined from the measuring variable and the compensating variable. The concentration of the gas in the measuring gas chamber is determined from the corrected measuring variable.
