Lump detectors eliminate stray light from fault detection

the WTVS-1 (wall thickness vision system). The system measures ID, OD, wall thickness and concentricity of single- and double-wall tubing using machine vision technology. The system can be used for off-line measurements on the production floor as well as in a lab environment. The significant system features include bench top configuration, high-resolution industrial camera, computer-controlled lighting, touch screen monitor, calibration using NIST traceable standard and fixed magnification or zoom options. The major advantages of the system include an easy-to-use interface, auto part finding, auto measurement algorithm and minimum operator intervention.

Other features include fully digital signal processing (DSP), microprocessor for intelligent fault analysis and classification, illuminated mobile operating and display unit, detailed error log, interface for host connection, compact design, flexible mounting concept, and a theoretically unlimited lifespan. Since faults often only cover a limited angle on the product circumference, eg lumps, neckdowns or blisters, two-axis detectors (X/Y) are usually used. However, reliability can be three times as high by using the three-axial measurement of the KW Trio models. This is due to the reduction in blind spots that the KW Trio models enable.

wire drawing and other processes, surface faults such as lumps and neckdowns must be detected immediately. Zumbach has developed a new concept to eliminate stray light as a factor in fault detection, in order to enable production processes with high quality on extrusion lines, optical fibre draw towers, etc. The combination of an electronic measuring principle and a complex optics solution is claimed to set a

ZUMBACH has launched the KW Trio three-axis lump detector range for extrusion lines, optical fibre draw towers, rewinding processes and others. A pulsing light source and automatic ambient light rejection after the cycle makes the detectors impervious to stray light. Line speed or iridescent light have no influence on measurement results, and even the smallest surface faults are reliably detected on a micrometre scale. In insulating, sheathing, enamelling,
