摘要： A gas sensor for measuring the concentrations of gases includes a solid body electrolyte, at least three electrodes, and a closed chamber. The doped platinum includes at least 50% by weight platinum and the remainder includes at least one further element selected from the group of solid body electrolytes. In particular, the doped platinum includes between 0.5% by weight to 15% by weight ZrO2 and the remainder is platinum, or the pure platinum is 100% by weight platinum and the gold alloy comprises at least 50% by weight gold and maximally 50% by weight platinum. In particular, the gold alloy includes approximately 85% by weight gold and approximately 15% by weight platinum or the gold alloy comprises at least gold and platinum at a ratio of 85% gold to 15% platinum.

摘要： An Al2O3 carrier has a thin-film structure of platinum or a platinum alloy arranged thereon. The carrier and/or the thin-film structure are adapted to reduce mechanical stresses owing to different thermal expansion coefficients. The carrier and/or the thin-film structure include a surface of the carrier in the region of the thin-film structure is smoothed at least in sections to reduce the adhesion and/or a surface of the carrier has an intermediate layer on which the thin-film structure is arranged. The thermal expansion coefficient of the intermediate layer is from 8*10−6/K to 16*10−6/K, in particular from 8.5*10−6/K to 14*10−6/K, and/or the thin-film structure has at least one conductor path that is undular at least in sections, said conductor path extends laterally along the surface of the carrier.

摘要： The invention relates to temperature sensors, in particular high-temperature sensors, having an optionally coated substrate, at least one resistor structure, and at least two connection contacts. The connection contacts electrically contact the resistor structure, and the substrate is made of zirconium oxide or a zirconium oxide ceramic stabilized with oxides of a trivalent metal and a pentavalent metal. The substrate is coated with an insulation layer and the resistor structure and the free regions of the insulation layer, on which no resistor structure is disposed, are at least partially coated with a ceramic intermediate layer. A protective layer and/or a cover is disposed on the ceramic intermediate layer. At least one electrode may be disposed, at least at one connection contact, alongside the resistor structure on the substrate. The invention also relates an exhaust-gas system for controlling and/or regulating an engine, particularly a motor vehicle engine, containing these temperature sensors.

摘要： A flow sensor element is provided having at least one temperature-measuring element and at least one heating element each having at least one platinum thin film resistor, the at least one temperature-measuring element and the at least one heating element each being arranged on a carrier element which is formed from a ceramic foil laminate or a multi-part ceramic component. The carrier elements have electrical conductor paths and junction surfaces for electrically contacting the at least one temperature-measuring element and the at least one heating element. The at least one temperature-measuring element and the at least one heating element each have a metallic carrier foil with an electrically insulating coating, on which the platinum thin film resistors are arranged. The flow sensor element may be used for mass through-flow measurements of gaseous or liquid media in pipe ducts, for example in an exhaust gas pipe of an internal combustion engine.
