PROTECTIVE ELEMENT FOR A PROBE, CORRESPONDING PROBE AND HONEYCOMB ELEMENT

摘要

The invention relates to a protective element (10) for attachment to a probe (8), especially a probe (8) for use in the exhaust gas system of a motor vehicle, whereby an inner surface (13) of the protective element (10) can at least partially be placed against an outer surface (14) of the probe (8). The protective element (10) comprises an at least temporarily water-binding layer (11) which chemically and/or physically binds water in a first operating state and releases the bound water in a second operating state. The configuration of the water-binding layer (11) of the protective element (10) according to the invention effectively prevents water shock on the probe (8) as water vapor is prevented from condensing out, especially in the cold start phase in the area of the probe (8) having the highest thermal capacity. The water-binding layer (11) temporarily binds the water in one operating state while it releases the water in a second operating state.
