NUCLEAR LEVEL SENSING GAUGE USING SCINTILLATING FIBER BUNDLE

摘要

A nuclear level sensing gauge (10) for measuring the level of product (16) i n a bin (14) utilizes a bundle (12) of scintillating fibers. A source (18) of nuclear radiation positioned adjacent the bin, and a bundle of one or more scintillating fibers is positionned adjacent the bin opposite the source of nuclear radiation such that nuclear radiation passing through the bin imping es upon the bundle. Circuitry detects scintillating photons generated in the fibers, which are indicative of radiation passing through the bin. The numbe r of photons generated in the fibers is representative of the level of radiati on- absorbing product in the bin.
