Exhaust sensor having flat plate ceramic sensing element and a sealing package

摘要

The invention includes a flat plate exhaust gas sensor having a plurality of layers of glass and steatite immediately surrounding a flat plate sensing element. A ceramic body surround each layer of solid-state sintered glass and steatite and extends from each layer to a protective metal housing. A ceramic plunger presses the layers of glass and steatite. The plunger surround electrical connectors to the sensing element to prevent damage to the connector from heat. <IMAGE>
