Abstract

Improvements in detection devices for length measuring devices, in particular for the length measurement of rolled steel products, characterized in that they consist of a light emitter and receiver comprising one or the other, but preferably the receiver, means for the formation of an analysis point or a linearly movable light path, this from a movable internal organ, driven in rotation, and because the cylindrical receiver comprises a cylindrical envelope with a window, transmitting the movable internal organ and a rectilinear interior element arranged in front of this slot, the luminous flux to some photosensitive elements.
