Patent number: 10107221Abstract: A method for producing a soot sensor is provided. The method includes steps of applying a contiguous metallic layer on an electrically insulating substrate and structuring the metal coating with a laser beam by vaporizing areas of the metallic layer. At least two interlaced contiguous electrically conductive structures are produced. The electrically conductive structures are spatially separated from one another with the laser beam and are electrically insulated from one another such that the conductive structures substantially extend next to one another and close to one another in an area relative to a total length thereof. A soot sensor produced using such a method is also provided. The soot sensor has an electrically insulating substrate and at least two contiguous electrically conductive structures which are spatially separated from one another and are interlaced as structured metallic layers. An intermediate space between the conductive structures is burned free with a laser.Type: GrantFiled: February 28, 2014Date of Patent: October 23, 2018Assignee: Heraeus Sensor Technology GmbHInventors: Karlheinz Wienand, Matsvei Zinkevich, Dieter Teusch

Patent number: 8730002Abstract: A resistance thermometer is provided having a measuring resistor in a form of a 0.1 to 10 ?m 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 ?m 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 ?m, and the structured platinum layer is covered by an electrical insulator.Type: GrantFiled: January 20, 2010Date of Patent: May 20, 2014Assignee: Heraeus Sensor Technology GmbHInventors: Karlheinz Wienand, Matsvei Zinkevich

Patent number: 8138881Abstract: A coated wire is solderable with soft solder while maintaining separate phases of the core and the coating. A 100 ?m to 400 ?m thick nickel wire may be coated galvanically with silver. For a film resistor with coated wires as connection wires, including a platinum measurement resistor on an electrically insulating substrate and connection wires connected to the measurement resistor, the connection wires have a coated nickel core. The coating may be made of silver or glass or ceramic or a mixture of these materials, or on its outside may be made of glass or ceramic or a mixture of these materials. For producing film resistors a thin metal or glass component is deposited on a connection wire connected to a track conductor arranged on an electrically insulating substrate, and a thick glass paste is deposited and fired on this metal or glass component. For mass production of film, several film resistors encased together in glass may be partitioned by fracturing.Type: GrantFiled: September 24, 2008Date of Patent: March 20, 2012Assignee: Heraeus Sensor Technology GmbHInventor: Matsvei Zinkevich
