Abstract
A zirconia type oxygen partial pressure sensor for use with an exhaust system wherein an electrical voltage signal is generated in response to an oxygen partial pressure differential across a solid electrolyte. A reference oxygen partial pressure is introduced into the interior of a solid electrolyte sensor through an aperture formed in a housing for the sensor, a protective clip, wire mesh or spring being provided to at least partially cover the aperture to preclude contaminants from being introduced to the interior of the sensor through the aperture. A ground terminal assembly is also provided to supply a ground for the device in addition to that provided by the threaded engagement between the shell of the O.sub.2 sensor and the exhaust system to which it is attached.
