摘要： A pressure sensor comprises an oxygen sensitive luminophoric material encased in a permeable material adjacent to the same or similar type of oxygen sensitive luminophoric material encased in an impermeable material where the contrast between the electromagnetic waves emitted from each luminophoric material provides an indication of the local oxygen pressure. Alternatively, a device comprising a photosensor and an electromagnetic wave source may be used to excite and interrogate an oxygen-sensitive luminophoric material and to deduce the local oxygen pressure, based on the intensity of the luminescent output of the luminophoric material. The information may be used to efficiently locate leaks in vacuum-bag assisted manufacturing processes, in locating gas leak-paths in a solid surface, or other pressure-sensing applications.

摘要： A device indicates the location of an air leak in a vacuum bag used to process composite parts. The device includes a layer of material on the inner face of the bag that changes in appearance due to an oxidation-reduction reaction in areas of the layer exposed to oxygen caused by a leak in the bag.
