    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 sensor, particularly an impedance sensor, for example a soot sensor, is provided which has two mutually electrically insulated electrodes, wherein at least one external electrode is formed from a composite of metal and inorganic oxide as a film pattern having a film thickness of 0.5 to 20 μm. The trace width of the film pattern and the spacing between the traces is 5 to 70 μm and the border region around the conductor trace edge varies less than 10 μm. Both electrodes can be arranged adjacent to each other as a film pattern in a plane. Preferably, the sensor has a heater. For mass production, electrodes are produced as a film pattern having a film thickness of 0.5 to 20 μm on electrically insulating oxide bases and, following full-surface imprinting of a metal powder and oxide-containing paste, the electrodes are structured particularly accurately as traces from the printed film. In particular, the film thickness of the printed film is reduced.

    摘要: A resistance thermometer is provided having a measuring resistor in a form of a 0.1 to 10 μm thick structured platinum layer applied to an electrically insulated surface of a substrate and an electrically insulating coating layer covering the platinum layer. The substrate or its surface contains zirconium dioxide, which is stabilized with oxides of a trivalent and a pentavalent metal. Preferably, the trivalent metal is yttrium and the pentavalent metal is tantalum or niobium. The characteristic curve of the measuring resistor preferably conforms to DIN-IEC 751. For mass production of resistance thermometers having high and reproducible measurement accuracy, a structured platinum layer having a thickness of 0.1 to 10 μm is applied to an electrically insulating substrate having a thermal expansion coefficient in the range of 8.5 to 10.5×10−6/° K and a roughness less than 1 μm, and the structured platinum layer is covered by an electrical insulator. The resistance thermometers allow precise temperature measurement between −200° C. and +850° C., preferably as a sensor in an exhaust gas treatment system. In a substance-sensitive sensor having a circuit path structure on a substrate, the circuit path structure has an epitaxially applied base layer, and a substance-sensitive metal layer attached to the epitaxially applied base layer.

    摘要: For mass production of anemometers for EGR systems with hot exhaust gas streams having temperatures up to 200° C. or 300° C., conductors and film resistors are placed onto a bed, and are covered on this bed, e.g. A sensor tip of the flow sensor of the anemometer is made of inorganic materials up to the housing cover. A cable is led into a housing and self-supporting electrical conductors are led through the housing cover. In the housing, leads of the cable are connected to the self-supporting electrical conductors. Using bed profiles passing through the cover, the film resistors are spaced from the housing sufficiently far that the film resistors and the housing are largely thermally decoupled. As an intermediate product, a measurement tip or a sensor bar as part of a sensor tip is made of purely inorganic components, in order to make the mass production efficient.

    摘要: A flow sensor element and a method for self-cleaning of the flow sensor element are provided, in which a temperature-measuring element and a heating element are arranged on a carrier element, and these elements can form a multiple-part ceramic component. The temperature-measuring element has a platinum thin-film resistor on a ceramic substrate for the temperature measurement and is heated with an additional platinum thin-film resistor. A measurement device, in particular an anemometric measurement device of a flow sensor, contains film resistors mounted in at least one opening of a cover or a hollow body. Two of the film resistors have resistance values differing by one to three orders of magnitude. The anemometric measurement device has a temperature sensor and a heat output sensor set in a carrier element. The temperature sensor has a temperature-measuring resistor and a heat conductor, as platinum thin-film or thick-film resistors, on a ceramic substrate.
