Abstract
An electrochemical measuring sensor for determining gas components and/or gas concentrations in gas mixtures, having a sensor element which has at least one signal-forming electrode having a supply lead of the signal-forming electrode and at least one electrical element whose electrical potential differs from the electrical potential of the supply lead of the signal-forming electrode. The supply lead of the signal-forming electrode is at least regionally surrounded by an electrically conducting shielding, so that fault currents appearing because of the potential difference between the supply lead of the signal-forming electrode and the electrical element flow at least predominantly between the electrical element and the shielding.
