Patent number: 7046116Abstract: A temperature probe is provided having a sensor element formed from a ceramic substrate and a platinum thin-film resistor arranged thereon. The platinum thin-film resistor is electrically connected with at least two terminal wires, with the at least two terminal wires each being electrically and mechanically connected with a contact pin in a connection area on their side facing away from the sensor element. The diameter of the terminal wires is smaller than the diameter of the contact pins, and the connection area is covered by a glass bead. Use of the temperature probe in a temperature range of about ?70° C. to +600° C. is ideal.Type: GrantFiled: November 10, 2003Date of Patent: May 16, 2006Assignee: Heraeus Sensor Technology GmbHInventors: Gerhard Damaschke, Bruno Rudnizki

Patent number: 6860635Abstract: A sensor, especially a temperature sensor, has a measuring resistor (7) including a substrate with an electrically insulating surface and a resistor layer situated thereon, which is enclosed by a housing (6) having current lead-ins to a plug system (1) for connection leads or contact pins (10) in a region of the housing facing away from the measurement. The measuring resistor (7) is arranged in the region of an end (14) of the housing facing the measurement, and between the measuring resistor (7) and the contact pins (10) at least one spacing element (9) of electrically insulating material is provided with lateral recesses for guiding the electrical connection leads (12) which extend from the measuring resistor (7). The temperature sensor can be simply adapted by variable configuration of the plug system and spacing element to various types of customer-specific requirements.Type: GrantFiled: March 8, 2002Date of Patent: March 1, 2005Assignee: Heraeus Electro-Nite International N.V.Inventors: Matthias Muziol, Michael Hoschkara, Gerhard Damaschke

Patent number: 6756585Abstract: For manufacturing a housing for sensor elements, a pliable material is introduced into the environment of the sensor element (2) by an injection molding process. In a first process step, the sensor element is injection-encapsulated by a soft plastic component (1), and in a second process step a hard plastic component (5) is applied thereon, which forms the outer housing for the sensor element (2). The sensor element (2) is provided with at least two connection leads (11), which are at least partially encapsulated by the soft plastic component (1). A sensor manufactured according to the process, especially a temperature sensor, is provided with a measuring resistor as a sensor element (2) on a substrate with an electrically conducting surface and the resistance layer situated thereon. The measuring resistor is encased by the soft plastic component (1), which in turn is encapsulated in a hard plastic component serving as a housing.Type: GrantFiled: March 8, 2002Date of Patent: June 29, 2004Assignee: Heraeus Electro-Nite International N.V.Inventor: Gerhard Damaschke

Patent number: 6622704Abstract: For reduction of toxic components in exhaust gases of internal combustion engines, particularly of nitrogen oxides in motor vehicles, a portion of the exhaust gases, essentially operating as inert gases, are recirculated into the combustion chamber of the engine for the purpose of reducing the peak combustion temperature. In the air intake region the engine is fed an adjustable mixture of partially recirculated exhaust gas and air, wherein the mass of in-flowing air and the mass of exhaust gas recirculated from the engine following its cleaning and cooling are fed respectively to its own flow rate sensor. From the determined mass flow amounts of in-flowing air and recirculated exhaust gas, an actual value signal is formed and compared with a target value signal dependent upon the respective performance specification. A regulation deviation of the actual value signal leads to an adjustment signal, which intervenes into the exhaust gas recirculation for the purpose of adjusting the amount recirculated.Type: GrantFiled: December 17, 2002Date of Patent: September 23, 2003Assignee: Heraeus Electro-Nite International N.V.Inventors: Karlheinz Wienand, Matthias Muziol, Karlheinz Ullrich, Gerhard Damaschke
