FIELD: physics.SUBSTANCE: during radial movement of the monitored article in a forward direction along the horizontal axis relative the detecting element of the device, a logic "1" information signal is generated at its first output, said signal bearing information on movement of the monitored article in the forward direction along the horizontal axis. In case of radial movement along the horizontal axis in the reverse direction, a logic "1" signal is generated only at the second output of the device. During radial movement along the vertical axis, a logic "1" signal is generated at the third output, said signal bearing information on movement of the monitored article in the forward direction along the vertical axis. In case of radial movement along the vertical axis in the reverse direction, a logic "1" signal is generated only at the fourth output of the device. Logic "0" voltage is generated at all other outputs in all cases.EFFECT: invention enables to monitor the direction of movement of articles along the horizontal and vertical axes without mechanical contact with said articles.2 cl, 5 dwg |
