Abstract: A gas sensor includes a metallic shell with a shell aperture extending therethrough along an axis; a metallic glass holder metallurgically sealed to the shell in order to prevent gases from passing between the glass holder and the shell, the glass holder including a glass holder aperture extending axially therethrough; a ceramic sensing element extending through the shell aperture and through the glass holder aperture; and a glass seal which seals between the sensing element and the glass holder in order to prevent gases from passing between the sensing element and the glass holder. A method of making the gas sensor is also provided.

Abstract: A gas sensor includes a metallic shell extending along a shell axis and defining a shell attaching surface that is substantially perpendicular to the shell axis; a metallic shield extending along a shield axis and defining a shield attaching surface that is substantially perpendicular to the shield axis; and a ceramic sensing element extending along a sensing element axis, the sensing element being rigidly fixed at a first axial location of the sensing element to the shell and the sensing element being laterally supported by the shield at a second axial location of the sensing element that is axially spaced apart from the first axial location. The shield is attached to the shell at an interface formed between the shield attaching surface and the shell attaching surface, thereby accommodating misalignment between the shield axis and the shell axis. A method of making the gas sensor is also provided.
