A converter of displacement includes scale, magnetic modulation head placed near the scale to which magnetic marks are applied with polarity that alternates, pulse former of excitation pulses to which excitation windings of magnetic modulation head are connected, recognizer of direction of motion in set of first flip-flop outputs of which are connected to the first and second differentiating circuits connected to the first inputs of the first and second AND gates, second inputs of those are connected to the outputs of the second flip-flop, and reversible counter. At that the first and the second signal windings of magnetic modulation head are connected to the first flip-flop, and the third-sixth signal windings – to the second flip-flop. Amplitude detector is placed, this is connected with inputs to the third-sixth signal windings of magnetic modulation head, and with the output – to information input of analog-digital transformer control input of which through OR gate is connected to the outputs of the first and the second AND gates. |
