A device for reading out information from profiled metal carrier comprises first reading inductive element, arranged above carrier surface, which start of winding is connected to first phase detector connected through signal conditioners to one of inputs of AND gates connected through decoding device to data processing unit, second and third reading inductive elements, arranged coaxially in the plane of two side faces of carrier, which starts of windings are interconnected and finish of windings is connected to second phase detector connected through signal conditioners to another inputs of AND gates, fourth and fifth reading inductive elements. Finish of primary winding of fourth reading inductive element is connected to first phase detector, and finish of primary winding of fifth reading inductive element is connected to finish of winding first reading inductive element. Concentrators of fourth and fifth reading inductive element are provided with additional first and second series connected matched windings, and starts of additional second windings are connected. |
