ABSTRACT:
Electrochemical sensor for determining the oxygen content in gases, particularly in exhaust gases from burners or internal-combustion engines, having an ion-conducting solid-electrolyte tube closed at one end and open at the other end for the entry of reference gas to the interior of the tube, a housing surrounding the open end of the tube, electrodes on the inner and outer surfaces of the tube connected to external leads via contact areas, an insulating hollow body on the open end of the tube between the tube and housing, contact areas on a transversal shoulder, conductor strips from the electrodes to the shoulder, a structural unit in the housing standing on the shoulder, radially disposed electric conductors in the structural unit with the lower ends touching the contact areas and the upper ends forming the external connections, and a spring urging the structural unit against the contact areas.
