ELECTRONIC MEASURING PROBE FOR DETERMINING THE OXYGEN CONTENT IN GASES, ESPECIALLY IN EXHAUST GASES

摘要

P A. THE INVENTION CONCERNS AN ELECTROCHEMICAL MEASURING PROBE FOR MEASURING THE OXYGEN CONTENT IN GASES, INCLUDING A SOLID ELECTROLYTE SENSOR ELEMENT 11 CONDUCTING OYXGEN IONS. /P P B. THIS PROBE IS CHARACTERIZED IN THAT THE SOLID ELECTROLYTE 32 IS AN ESSENTIALLY FLAT PLATE WITH A LARGE SURFACE CARRYING THE REFERENCE ELECTRODE 34 AND IS COVERED BY A COVER 35 ASSEMBLED WITH PLATE 32, AN EMPTY SPACE 36 FOR THE REFERENCE WAY BEING FORMED BETWEEN PLATE 32 AND COVER 35. /P P C. THE INVENTION IS APPLICABLE IN PARTICULAR TO DETERMINE THE OXYGEN CONTENT OF EXHAUST GASES FROM INTERNAL COMBUSTION ENGINES. /P
