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.
Claims2
An oxygen gas analyzer having a solid-electrolyte partition wall with electrode films attached to the sides thereof and serving to generate a detection signal proportional to the difference between the oxygen concentrations on the two sides of said partition wall;
- each of said electrode films comprising a metal powder having a particle size which gradually decreases toward the deepest region of the film adjacent said partition wall;
- platinum screens bonded to said electrode films;
- and
- leadwires secured to said platinum screens for providing a detection signal therethrough.
