Method for attaching a sensor at an exhaust gas treating device

摘要

The method involves providing an exhaust gas processing device (1) with a ceramic insert (3) e.g. substrate. The ceramic insert is fixed in a metallic housing (2) by a support mat (5), where one of the housing and the mat is penetrated by the housing. A retaining opening (7) that retains a sensor (6) is penetrated into the ceramic insert and produced by the ceramic insert by a drilling process and/or chipping process, where the insert is fixed in the opening and inserted in the housing. An independent claim is also included for an exhaust gas processing device e.g. particle filter and catalyzer, for an exhaust gas system of an internal combustion engine in a motor vehicle.
