    摘要: A measuring sensor is described for determining a physical property of a measured gas, especially for determining the oxygen concentration or the pollutant concentration in the exhaust gas of internal combustion engines, which has a sensor element that is exposable to the measured gas which is at least partially coated with a protective layer that protects against harmful components in the measured gas. In order to achieve producing a “contamination protection”, that is cost-effective from a manufacturing technology point of view, particularly against silicon compounds and phosphorus compounds, the protective layer (26) is made of highly active γ- or δ-aluminum oxide (Al2O3) having additives of compounds of the alkaline metals group, the alkaline earths group, the IV B subgroup or the lanthanides group.

    摘要: An unheated planar sensor element for determining the concentration of a gas component in a gas mixture, in particular the oxygen concentration in the exhaust gas of an internal combustion engine, has a sensor foil made of a solid electrolyte with an outer electrode exposed to the measuring gas, and an inner electrode exposed to a reference gas, as well as a reference-gas channel, which is covered by the sensor foil on one side and accommodates the inner electrode. To produce a small-volume, cost-effective unheated sensor element for use in small combustion engines having low power output yet sufficiently satisfactory measuring accuracy, the reference-gas channel is sealed on the underside by an additional sensor foil made of a solid electrolyte, and covered by an inner electrode lying inside the reference-gas channel and an outer electrode exposed to the measuring gas.

    摘要: A sensor element is described for determining a physical property of a measuring gas, in particular the pressure or the concentration of a gas component in a gas mixture, in particular in the exhaust gas of an internal combustion engine. The sensor element has an electrode exposed to the measuring gas and a reference electrode exposed to a reference gas, ambient air in particular, through a porous volume. The two electrodes are separated from one another by a solid electrolyte. To avoid premature aging of the reference electrode as a result of deposits of foreign substances contained in the reference gas or of chemical interactions caused by the foreign substances, the volume material is selected with respect to its physical and chemical properties in such a way that the foreign substances are bound in the volume and/or are subjected to a chemical reaction.

    摘要: A gas sensor for detecting particles in a gas stream has a first electrochemical pump cell, which has a measuring chamber in which a first electrode is disposed to pump particles between the first measuring chamber and the gas stream. Furthermore, a second electrochemical pump cell is provided, which has a second measuring chamber in which a second electrode is disposed so as to pump particles. The second measuring chamber is connected to the gas stream via an absorber medium for absorption of the particles to be detected. This makes it possible to absorb the particles to be detected in a first operating mode using the absorber medium, and to desorb the absorbed particles in a second operating mode, and to detect the quantity of the desorbed particles. Thus, the gas sensor is able to take even low concentrations into account, and short-term measuring errors do not have such a serious effect.

    摘要: A sensor for determining gas components and concentrations in a gas mixture that is particularly suitable for analyzing HC, NOx and CO in exhaust gases of internal combustion engines in the sensor, an outer electrode, that is separated from an MOx electrode by an electrolyte layer, is applied on a substrate. In this context, the outer electrode and the MOx electrode are in communication with the gas mixture to be analyzed. In addition, the outer electrode contains a region that is in contact with a gas-permeable tunnel layer which in turn contains a region that is directly exposed to the gas mixture to be analyzed, so that the gas to be analyzed can be supplied to the outer electrode via the gas-permeable tunnel layer.
