Abstract

The invention concerns a device for detecting and locating leakage fluids in sealing systems, said device being characterized by a single-layer flat structure (4) which comprises electrically conductive particles and/or fibres and is disposed all-over the exterior of a sealing region to be monitored. The flat structure comprises an area-specific electrical resistance which, when wetted with an electrically conductive fluid, decreases in the region of the wetting and, when wetted with an electrically non-conductive fluid, increases in the region of the wetting. The flat structure (4) is further provided with a plurality of measuring contacts (5, 6) which are connected via one or a plurality of bus transmission lines to a measuring and evaluating arrangement (9) by means of which the electrical resistance of the flat structure (4) and/or the potential distribution can be measured in relation to a counter electrode disposed on the interior of the sealing region to be monitored, and a variation in the local resistance distribution and/or potential distribution within the flat structure (4) can be determined.
