摘要： A sensor for determining an oxygen level in an exhaust gas of an internal combustion engine includes a receptacle arranged in a longitudinal bore of a metallic enclosure for a sensor element. The sensor element is accommodated in a gas-tight manner using a sensor element seal. The receptacle has a measured gas-side ceramic molded component and a connection-side ceramic molded component, which are arranged one behind the other axially. A hollow space is formed between the measured gas-side ceramic molded component and the connection-side ceramic molded component, in which a metallic sealing element is hot-pressed.

摘要： An electrochemical sensor for determining the oxygen concentration in gas mixtures is proposed. The sensor has a solid electrolyte (10) with oxygen ionic conductivity, which has a measuring electrode (11) that does not catalyze establishment of equilibrium of the gas mixture and is exposed to the gas mixture. The measuring electrode (11) contains platinum and bismuth. The effect of these materials is that the free oxygen contained in the gas mixture is preferentially adsorbed, without reacting with the other gas components such as CO and HC.

摘要： A layer system (11, 12) and a process for producing such a layer system is proposed which serves, in particular, to produce exhaust gas sensors. The modified layer system according to the invention advantageously contains very finely dispersed and highly reactive mixed oxides of alkali metals and at least trivalent elements on or in the porous covering layer (12), which mixed oxides exhibit an improved gettering action with respect to all the contaminants from the exhaust gas. Exhaust gas sensors having a layer system according to the invention are largely insensitive to contaminants from the exhaust gas.
