摘要： A device and method for measuring combustible-gas concentration and a device and method for measuring hydrocarbon-gas concentration, which exhibit low dependence on oxygen concentration variations as well as low temperature dependence. Paste is applied to the inner surface of a closed-bottom cylindrical solid electrolyte element, thereby forming a layer serving as a reference electrode. Plating with platinum is performed, so as to form a layer serving as a first detection electrode, on the outer surface of the solid electrolyte element only at a portion extending from an end portion of the solid electrolyte element to the vicinity of the interface between a heating resistor and a heating-resistor lead portion, which are formed within a heater element contained in the cylindrical solid electrolyte element. Paste which contains gold powder and 10 parts of indium oxide is applied onto the platinum-plating layer so as to form a layer serving as a second detection electrode, followed by firing. Subsequently, a diffusion layer containing spinel is formed by thermal spraying on the surface of a detection electrode. The heater element is disposed in the solid electrolyte element such that an end portion abuts an inner bottom portion of the solid electrolyte element. Lead wires for measuring internal resistance, which extend from the reference electrodes, and a lead wire extending from the detection electrode are connected to a temperature controller.

The residual oxygen concentration of the second processing chamber 5 is determined on the basis of a second oxygen pump current flowing between the second inner and outer electrodes 10 and 11, whereby the concentration of combustible gas components contained in the gas under measurement is determined.

摘要： A gas sensor which can detect the concentration of a combustible gas component in a measurement gas with high accuracy even when the oxygen concentration of the measurement gas or the element temperature changes and which has an excellent response in detecting the combustible gas component is disclosed. In a gas sensor 1, the oxygen concentration of a measurement gas is adjusted to a predetermined level within a first processing space 9 through operation of a first oxygen pump element 3. The measurement gas having an adjusted oxygen concentration is then introduced into a second processing space 10, where a combustible gas component is burned through the assistance of electrodes 16 and 17 functioning as oxidation catalyst sections. Constant voltage is applied to a combustible gas component concentration detection element 5. In this state, when the amount of oxygen changes due to the combustion of the combustible gas component, the output current of the combustible gas component concentration detection element 5 changes with change in the amount of oxygen. Therefore, information regarding the combustible gas component concentration of the original measurement gas can be obtained from the value of the output current. Further, oxygen required to burn the combustible gas component within the second processing space 10 is supplemented by a second oxygen pump element 6. Unlike conventional apparatuses, no feedback system is used, and a variation in the concentration of the combustible gas component appears directly as a variation in the current of the combustible gas component concentration detection element 5. Therefore, a high detection response is obtained.
摘要翻译：公开了一种气体传感器，其即使在测量气体或元件温度的氧浓度变化并且在检测可燃气体成分时具有优异的响应性的情况下也可以高精度地检测测量气体中的可燃气体成分的浓度。在气体传感器1中，测量气体的氧浓度通过第一氧气泵元件3的操作在第一处理空间9内被调节到预定水平。然后将具有调节氧浓度的测量气体引入第二处理空间10，其中通过用作氧化催化剂部分的电极16和17的帮助燃烧可燃气体组分。恒定电压被施加到可燃气体成分浓度检测元件5上。在这种状态下，当由于可燃性气体成分的燃烧而导致氧气的变化时，可燃性气体成分浓度检测元件5的输出电流随着氧气量。因此，可以从输出电流的值获得关于原始测量气体的可燃气体成分浓度的信息。此外，在第二处理空间10内燃烧可燃气体成分所需的氧被第二氧气泵元件6补充。与常规装置不同，不使用反馈系统，并且可燃气体组分的浓度的变化直接作为可燃性气体成分浓度检测元件5的电流的变化。因此，获得高检测响应。
