摘要： An oxygen analyzing method for determining a positive or negative oxygen concentration of a measurement gas which changes between oxidizing and reducing atmospheres. The method uses a sensing element having an oxygen sensing cell wherein an electromotive force is induced between its measuring and reference electrodes according to the principle of an oxygen concentration cell. The atmosphere adjacent to the measuring electrode is controlled by controlling a pumping current to be applied to an oxygen pumping cell such that the electromotive force induced in the sensing cell is maintained at a predetermined level. A heater is provided to heat the sensing and pumping cells, to maintain their operating temperature within a range of 700.degree.-960.degree. C. The pumping current, or a signal to control the pumping current, is converted into an oxygen concentration signal whose level is held within one of a positive range and a negative range. The concentration signal represents the positive oxygen concentration of the oxidizing atmosphere, or the negative oxygen concentration of the reducing atmosphere.

摘要： A gas sensing element having a co-fired laminar structure including an electrochemical cell having a planar solid electrolyte body, and at least two electrodes disposed on the planar solid electrolyte body. The sensing element further includes two generally planar heaters which are formed on opposite sides of the electrochemical cell, respectively, and which are spaced apart from each other in a direction perpendicular to the planar solid electrolyte body, and a generally planar thermosensitive portion formed as an integral part of the laminar structure, for detecting a temperature of the laminar structure in the neighborhood of at least one of the electrodes of the electrochemical cell. The thermosensitive portion may partially define a diffusion chamber into which a measurement gas in an external space is introduced under a predetermined diffusion resistance, so that one of the electrodes is exposed to the introduced measurement gas.
