摘要： An oxygen sensor comprising a hollow cylindrical member closed at one end but open at the other to admit a reference gas. There is at least one radial through-hole in the hollow cylindrical member. An oxygen-ion conductive solid electrolyte later has at least one pair of electrodes on its opposite sides. The electrolyte layer is wrapped around the hollow cylindrical member with the electrode on its inner side facing the through hole. In other embodiments, an oxygen sensor is provided which is very insensitive to the direction of flow of the gas to be analyzed. The electrodes of the sensor are spaced at substantially equal intervals on the circumference of a cylindrical solid electrolyte layer in registry with through-holes formed in a hollow tubular member surrounded by the electrolyte layer. A heating unit may be formed on either the inner or outer surface of the solid electrolyte layer.

摘要： An apparatus for evaluating an oxygen sensor includes a device for mixing a fuel and an oxygen-containing gas in an appropriate ratio to prepare a fuel mixture. A burner is connected to the mixing device for burning the fuel mixture to produce a gaseous combustion product. A tubular member extends from the burner for supplying the combustion product. A nozzle is connected to the tubular member for introducing a fuel and an oxygen-containing gas into the tubular member so that the combustion product is of a desired excess air ratio (air-fuel ratio) and a mounting device for the sensor to be evaluated is disposed on the tubular member, downstream of the nozzle.
