ABSTRACT:
A detector for continuously monitoring the integrity of a coating on a piece of material. The detector includes an upper bar and a lower bar held near the surfaces of the material. Each bar carries multiple conductive probes in contact with the corresponding surface and electrically connected to an electronic detection circuit. Adjacent probes are connected to electric terminals having different voltage potentials. When probes from the same bar carrying different voltages short together, such as by contacting the surface of conductive sheet material, the detection circuit signals an insufficiently coated area has been found. The short between probes must be large enough to cause a short for more than a predetermined time. The upper probe bar is rotatable to prevent damage to the upper probes by a bent edge on a sheet of material.
