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： A temperature-dependent measuring resistance with rapid response time is at least partially arranged on an electrically insulating surface of a ceramic substrate, wherein a portion of the conductor path spans a recess situated in the substrate in a bridge-like manner, and the remaining portion of the conductor path in the edge area of the substrate adjacent to the recess is provided with connection contact fields. The conductor path comprises a platinum or gold layer, wherein the conductor path is partially provided with a cover layer of glass, and wherein the connection contact fields are exposed. In a further embodiment, the conductor path is arranged together with the connection contact fields either on a screen-printed glass membrane or on a thin film membrane applied in a PVD process, which covers the surface of the ceramic substrate and spans the recess. The cover layer is likewise selectively applied by screen printing in case there is a glass membrane. In the case of a thin film membrane, the cover layer is also applied selectively by a PVD process and can be the same material as the thin film membrane. The ceramic substrate preferably comprises aluminum oxide.
