Beta-Ray Gauging System
The BYTASCAN uses the principle of Beta ray transmission through the material to measure its density, weight and thickness usually indicated in g/m2 or μm.
The beta-ray source is fixed inside the transmitter housing, while another housing contains the receiver which is positioned above the transmitter at a known distance (gap). When a material is positioned between the transmitter and receiver, part of the energy emitted by the source is absorbed by the material. The missing part, captured by the receiver, is proportional to the density of the measured film. Once the width and density are known, the system can calculate both weight and thickness.
