The RAYXSCAN uses an X ray beam transmission through the homogeneous material to be measured, from which it can measure the thickness, usually shown in mm or the weight shown in [g/m2]. An X-ray source is situated in a housing, while another housing contains the receiver and is positioned opposite the transmitter at a set distance (Gap).
The film runs between the transmitter and receiver and the two housings containing the transmitter and receiver run across the web width. When a homogeneous layer of material is positioned between the transmitter and receiver, part of the energy transmitting to the receiver is absorbed by the material. The energy measured by the receiver is attenuated and compared to the energy without the material and allowing for the material physical proprieties the system can calculate the ratio between the attenuation and the material weight.
Following the regulations EURATOM 96/29, RaYxscan is not considered a radioactive source because the tension on the anode is lower than 5 kV, for this reason this scanner does not need to follow the radio protection regulations and hence a safety certificate is not necessary.
