ABSTRACT:
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 surrounds 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 surrounds electrical connectors to the sensing element to prevent damage to the connector from heat.
