Abstract
The invention has an X-ray emitting tube and a linear detector on opposite sides of a plane containing a strip to be measured and an electronic acquisition, measuring and control unit. A mask transversely moveable relative to the strip occludes radiation from the X-ray emitting tube which is not intercepted by the strip or which passes through the edge region of the strip. This device offers an improved degree of precision measurement near the edge of the strip.
