  • Metal to ceramic seal
    Patent number: 9354215
    Abstract: A gas sensor includes a sensing element formed on a ceramic substrate, an insulator surrounding at least a portion of the sensing element, and a metal shell surrounding at least a portion of the sensing element. The gas sensor further includes a cured ceramic adhesive structure bonded to the insulator and the sensing element, to the insulator and the metal shell, or to the sensing element and the metal shell. The ceramic adhesive structure is disposed so as to mitigate gas leakage through the gas sensor.
    Type: Grant
    Filed: August 26, 2013
    Date of Patent: May 31, 2016
    Assignee: Delphi Technologies, Inc.
