Width Measurement of Profiles with Glass Fiber Optic Light Curtains and Fiber-Optic Amplifiers
In the production of metal profiles, the presence and dimensions of the objects must be detected before a clamping device secures them in place. Profiles can be black, white, chrome, glossy or matt. Glass fiber optic light curtains based on the transmitter-receiver principle are used in confined spaces, together with a universal reflex sensor. The optical fibers are arranged in a single line to create a light band. The width is measured, the linear signal is output proportional to the glass fiber cover and the correct position is determined.
