  • Patent number: 11242792
    Abstract: Various embodiments include a method for the production of a sensor for an exhaust gas stream of an internal combustion engine, wherein the sensor comprises a first electrode and a second electrode. The method comprises: arranging a glass solder in a mold substantially between and substantially insulating the first electrode and the second electrode; arranging an insulating element in the mold in contact with a free surface of the glass solder; and finish molding the glass solder into a glass insulator together with the insulating element in a predetermined position relative to the first electrode and the second electrode. The insulating element shapes the glass insulator during the finish molding and at least partially isolates the glass insulator from the exhaust gas of the internal combustion engine during a measuring operation of the sensor.

  • Patent number: 11098632
    Abstract: A particle sensor which has a housing, in which a measuring region extending along a longitudinal axis is arranged, a sensor electrode, which is arranged in the measuring region and has a measuring section, which extends coaxially to the longitudinal axis, and a flow conducting element, which is arranged in the measuring region and has at least one first flow conducting section, which extends coaxially to the longitudinal axis, and at least one second flow conducting section, which extends coaxially to the longitudinal axis and which is arranged with respect to the longitudinal axis within the first flow conducting section. The measuring section, the first flow conducting section and the second flow conducting section are arranged engaging in one another such that the measuring section is arranged with respect to the longitudinal axis between the first flow conducting section and the second flow conducting section in the radial direction.

  • Patent number: 10613013
    Abstract: Various embodiments may include a sensor for a motor vehicle including an anode conductor, an anode sleeve connected to the anode conductor, an adapter sleeve, a housing, a connection between the housing and the adapter sleeve, and a cathode sleeve connected to the housing. The anode conductor is rigidly connected to the adapter sleeve by an electrical insulator. The anode sleeve and the cathode sleeve are arranged coaxially with respect to one another within the scope of the production tolerances.

  • Publication number: 20180202914
    Abstract: A sensor, such as an electrostatic particle sensor, having a housing in which a sensor element is disposed, and a gas-tight electrical feedthrough through the housing, the feedthrough being configured for directing electrical currents and/or voltages from electrical components that are disposed outside the housing into the housing and/or out of the housing. In order for a sensor which permanently has at least one gas-tight electrical feedthrough through the housing thereof to be provided, the electrical feedthrough has a ceramic molded body which has at least one through bore, the latter having a first end and a second end, wherein the through bore from the first end up to the second end is filled with a metallic paste, and the ceramic molded body in a sintering process is connected to the metallic paste, and in the region of the first end and/or of the second end of the through bore at least one metallic tube piece is attached to the sintered metallic paste.
