An oxygen sensor comprising: an elongated planar sensing element; a tubular shield within which at least a portion of the sensing element extends; a seal sealably mounting the sensing element within the tubular shield; a shell for mounting the oxygen sensor to a body through which exhaust flows; and an annular gasket seating at a first surface the tubular shield and at a second surface an annular seat of the shell, wherein there is no direct contact between the tubular shield and the shell. An advantage of improved shock resistance is obtained, preventing damage to the seal, which may be made of glass.

Oxygen sensor with annular support member providing improved mechanical

The invention includes a sealing system for a heated flat plate exhaust gas sensor having a plurality of alternating layers of glass and steatite surrounding a flat plate sensing element. A ceramic tube surround the plurality of layers. The ceramic tube is carried in a tubular-shaped metal housing.
