Abstract:
1. An elongated gas sensor apparatus extending generally along a longitudinal axis, comprising: a ceramic substrate including a first major surface and a second major surface opposite the first major surface, the first and second major surfaces orientated perpendicular to the longitudinal axis of the gas sensor apparatus; a gas sensor element comprising a heater element supported by the first major surface of the ceramic substrate, and a plurality of electrodes supported by the second major surface of the ceramic substrate, wherein at least some of the plurality of electrodes supported by the second major surface of the ceramic substrate are in contact with a sensing material, wherein the sensing material is a different material than the ceramic substrate; and a metallic housing surrounding said gas sensor element, the metallic housing comprising an outer baffle and an inner baffle, wherein the inner baffle is shaped to direct a flow of exhaust gas towards said gas sensor element.
