ELKOMETER 200 provides yarn producers and converters with a high-volume precision tool for off-line defect detection. A powerful yarn take-off unit guides up to eight parallel positioned yarn samples through PROMPT OLO online sensors. Defects such as thin- and thick places, broken filaments and fluff are detected and reported in terms of quantity and position. If an in-depth defect analysis is requested, images of each detected defect can be generated by means of the optional DEFECT VIEW camera system, which is installed at one of the positions. Additionally to the pure inspection mode, a special defect assessment mode enables human inspection by stopping the system after each detected defect.
