Abstract
In an exemplary embodiment, the present invention provides an exhaust constituent sensor comprising a planar sensing element securely held in place within a tubular shield by disposing a high temperature mat support between the tubular inner shield and the planar sensing element. The high temperature mat support comprises suitable mat material, e.g., ceramic fibers or metal mesh, and preferably, comprises silica fibers, alumina fibers, alumina fibers with vermiculite, or any other suitable mat material providing the desired support, strength, and thermal and electrical insulating properties described herein. It is within the scope of the invention that the high temperature mat support may be in the form of a fibrous material or a more rigid perform structure, wherein in both instances, the high temperature mat support is adapted to be disposed concentrically around the planar sensing element for secure packaging thereof.
