System and method for use with apparatus for sensing bare metal on a moving strip of insulatively coated conductive material

摘要

A detector for detecting bare metal on a moving strip of insulatively coated conductive metal includes a plurality of sensors arranged along the edges of both sides of the strip. Each sensor includes a plurality of voltage biased contacts and a grounded contact. The inventive control system provides an actuate pulse when two voltage biased contacts on one sensor are electrically connected to the grounded contact of another sensor in accordance with the Boolean Function: [(AB+BC+CA)x(DE+EF+FD)]+[(GH+HJ+JG)x(KL+LM+MK)]+[(AB+BC+CA)x(GH+HJ+JG) ]+[(DE+EF+FD)x(KL+LM+MK)] where the letter designations alphabetically identify the voltage biased contacts of each sensor.
