Apparatus for oxygen determination

Abstract

Abstract APPARATUS FOR MEASURING OXYGEN CONTENT OF FLUIDS AT ELEVATED TEMPERATURES BY MEANS OF A GALVANIC CELL WITH A SOLID OXIDE ELECTROLYTE AND A REFERENCE ELECTRODE OF A MIXTURE OF A METAL AND ITS OXIDE INCLUDES A SENSOR WHICH COMPRISES A REFRACTORY BODY MEMBER HAVING A FIRST LONGITUDINAL OPENINGS FOR RECEIVING A FUSED SILICA TUBE WHICH HAS THE SOLID ELECTROLYTE FUSED TO THE END THEREOF WHICH CONTACTS THE FLUID. A ROD OF MOLYBDENUM OR OTHER CONDUCTOR EXTENDS THROUGH THE TUBE WITH THE REFERENCE ELECTRODE BETWEEN THE END OF THE ROD AND THE SOLID ELECTROLYTE. A SECOND FUSED SILICA TUBE EXTENDS THROUGH A SECOND LONGITUDINAL OPENINGS ADJACENT THE FIRST OPENING AND CONTAINS A SECOND ROD OF THE SAME MATERIAL AS THE FIRST. THE SECOND ROD ALSO HAS ITS FIRST END EXTENDING INTO THE FLUID. A THERMOCOUPLE EXTENDS THROUGH THE BODY MEMBER WITH ITS FIRST END EXTENDING INTO THE FLUID AND ITS SECOND END CONNECTED TO A CONNECTOR. A STEEL LANCE HAS MEANS AT ONE END FOR RECEIVING THE CONNECTOR AND SECOND ENDS OF THE RODS, AND MEANS AT THE OTHER END FOR CONNECTING TO A VOLTAGE MEASURING MEANS. IN SOME INSTANCES THE THERMOCCOUPLE MAY BE OMITTED. D R A W I N G
