Abstract

An electrochemical oxygen sensor with a measuring electrode, an atmospheric oxygen electrode as a reference electrode, and an auxiliary electrode in an electrolyte is improved such that a stable measured signal is obtained even during changes in the position of the measuring cell. To accomplish this, the auxiliary electrode is arranged in the vicinity of the measuring electrode and a protective electrode is provided between the measuring electrode and the auxiliary electrode.
