  • Patent number: 6565723
    Abstract: An exhaust gas sensor element has an electrolyte body, an inner electrode disposed on an inner surface of the electrolyte body, an outer electrode disposed on an outer surface of the electrolyte body, and a ground isolating coating disposed over the outer electrode. The ground isolating coating is typically alumina and extends from an active end of the electrolyte body toward an opposing end of the electrolyte body. The invention also includes a method for constructing a gas sensor element, the steps of which comprise forming an electrolyte body having an inner surface and an outer surface, applying an electrode ink to the inner surface to form an inner electrode and to the outer surface to form an outer electrode, and depositing a combination poison resistant/ground isolating coating, which is typically alumina, over the outer surface such that the combination coating extends from an active end of the electrolyte body toward an opposing end of the electrolyte body.
