ABSTRACT:
An oxygen gas analyzer is provided having a solid-electrolyte partition wall generating a detection signal proportional to the difference between the oxygen concentrations on each side of the wall. Electrode films attached to each side of the wall are comprised of a metal powder having a particle size which becomes gradually smaller toward the partition wall. Platinum screens are bonded to the electrode films and leadwires are welded to the platinum screens for providing a detection signal therethrough. Advantageously, this structure provides improved bonding strength between the electrode films and the leadwires while also providing a short response time.
