NUCLEAR LEVEL SENSING GAUGE USING SCINTILLATING FIBER BUNDLE

摘要

A nuclear level sensing gauge for measuring the level of product in a bin utilizes a bundle of scintillating fibers. A source of nuclear radiation positioned adjacent the bin, and a bundle of one or more scintillating fibers is positioned adjacent the bin opposite the source of nuclear radiation such that nuclear radiation passing through the bin impinges upon the bundle. Circuitry detects scintillating photons generated in the fibers, which are indicative of radiation passing through the bin. The number of photons generated in the fibers is representative of the level of radiation-absorbing product in the bin.
