ABSTRACT:
A galvanic exhaust gas sensor having a solid electrolyte disc having a porous electrode thereon for detecting oxygen partial pressure in an exhaust gas stream varying in its flow and composition and having a shield protecting the porous electrode from direct impingement of exhaust gas stream. The shield includes means for accelerating exhaust gas from across the disc face at exhaust gas stream velocities and pressures below a preselected level and for maintaining said flow more constant at exhaust gas stream velocities and pressures above the preselected level, effective to more accurately sense variations in oxygen content of the exhaust gas stream at a porous electrode.
