Paper basis weight detector |
摘要 |
Apparatus for continuously determining the basis weight of paper simultaneously at multiple points across the full width of a substrate. The apparatus includes a radioactive source which extends across one side of the web of paper. A detector array, on the opposite side of the substrate, detects the emission from the source. The array includes scintillating fibers and multi- or single-anode photomultipliers which may be connected by a scintillating or non-scintillating fiber optic elements to the photomultiplier.
