1. A honeycomb body assembly, comprising:
- a honeycomb body having one partial volume, at least one further partial volume, a first end face, a second end face and passages through which a fluid can flow, said passages extended between said first end face and said second end face; and
at least one measurement sensor at least partially extended into said honeycomb body;
said one partial volume being disposed between said first end face and said at least one measurement sensor, said one partial volume having an exchange of fluid flows between adjacent passages and having passage walls defining said passages, said passage walls having apertures formed therein at least in said one partial volume, and said one partial volume having a lower capacity to take up oxygen than said at least one further partial volume;
said at least one further partial volume having passage walls, andsaid passage walls do not permit an exchange of fluid flows between adjacent passages.

Abstract
A honeycomb body assembly includes a honeycomb body with channels through which a fluid can flow. The channels extend between two end faces. At least one sensor extends at least partly into the honeycomb body. A first partial volume of the honeycomb body is defined between a first end face and the at least one first sensor. The honeycomb body has a lower capacity for oxygen in the first partial volume than in at least one further partial volume. An exhaust system with a space-saving configuration of such a honeycomb body is also disclosed.
