Abstract:
1. A honeycomb body, comprising: a tubular casing; an extruded ceramic honeycomb structure through which a fluid can flow, said honeycomb structure being disposed in said tubular casing, said honeycomb structure having cavities and walls at least partially formed by porous material, said honeycomb structure having a circumferential outer surface; at least three axial subregions disposed along a longitudinal direction of the honeycomb body, said at least three axial subregions including at least one axial securing region, at least one axial sealing region and at least one axial measurement sensor region; at least one flexible or elastic mat disposed between said honeycomb structure and said tubular casing in said at least one axial securing region and said at least one axial sealing region; said honeycomb structure being connected to said tubular casing in said at least one axial securing region with a connection applying greater holding forces to said honeycomb structure in said at least one securing region than in said at least one measurement sensor region, said connection between honeycomb structure and said tubular casing being produced by said mat, said connection being a force locking connection through the use of a press fit, a quotient of holding force in said at least one securing region to a holding force in the sealing region is greater than or equal to two; and said at least one axial measurement sensor region having a recess formed therein for accommodating at least one measurement sensor in said honeycomb structure, said recess being formed in said circumferential outer surface, said at least one measurement sensor region being at least a circumferential region of the recess.
