Patent number: 10024432Abstract: A sensor system, for sensing at least one property of a measured gas in a measured-gas space, includes a probe for sensing the property of the measured gas. The probe has at least one sensor element and at least one housing surrounding the sensor element. The housing is configured so that the sensor element in the housing is capable of being impinged upon with the measured gas. The sensor system also includes a receiving element connectable to a wall of the measured-gas space. The probe is introducible along an insertion axis into the receiving element and securable in the receiving element. The probe is capable of being sealed off from the measured-gas space by at least one seal. The seal encompasses at least one linear seal.Type: GrantFiled: February 27, 2014Date of Patent: July 17, 2018Assignee: ROBERT BOSCH GMBHInventors: Markus Linck-Lescanne, Juergen Wilde, Bastian Buchholz, Narendiran Doraisamy

Patent number: 8038933Abstract: A gas sensor is for determining at least one physical quantity of a gas, e.g., an exhaust gas of an internal combustion engine, the gas sensor having a sensor element that is fixed in a housing of the gas sensor by a seal assembly. The seal assembly includes a sealing element, which has a ceramic and/or a metallic material. After the heat treatment, the sealing element has a maximum decrease in volume of 5 percent, or an increase in volume, based on the volume of the sealing element prior to the heat treatment.Type: GrantFiled: July 26, 2007Date of Patent: October 18, 2011Assignee: Robert Bosch GmbHInventors: Helmut Weyl, Claudio De La Prieta, Andreas Hachtel, Thomas Schulte, Thomas Egner, Juergen Wilde, Markus Siebert, Michael Kupzig, Uwe Glanz, Rainer Mueller, Leonore Schwegler, Petra Kuschel, Andreas Pesch

Patent number: 7493796Abstract: A sensor is described for determining a physical property of a gas that is to be measured, especially the pressure, the temperature or the concentration of a gas component in the exhaust gas of internal combustion engines, which has a sensor element supported in a sensor housing whose gas-sensitive sensor section protrudes from the sensor housing, and has a protective tube that surrounds the sensor section. In order to achieve an effective protection of the gas-sensitive sensor section from water drops and solid substances included in the exhaust gas, in conjunction with cost-effective production of the protective tube, protective tube is developed spiral-shaped, yielding a tube wall that is spiral-shaped in cross section.Type: GrantFiled: March 2, 2005Date of Patent: February 24, 2009Assignee: Robert Bosch GmbHInventor: Juergen Wilde
