Measurement of round and flat profiles

FOR the online measurement of flat and round profiles in hose and tube extrusion lines Sikora offers the Laser Series 2000 Profil. The gauge heads provide accurate measurements of the height and width, even when the profile twists by ±5 ° . The technological background of the devices is a state-of-the-art CCD-line sensor technology, combined with laser diodes as light sources and an intelligent powerful software. The outstanding feature of the non- contact measuring technology is the extremely high single value precision, which is an important aspect for the calculation of the standard deviation. The short exposure time assures reliable readings at all common line speeds. Product vibrations have no influence on the measurement. A benefit of this technology is that no guide rollers are needed to dampen frequency and amplitude of vibration. A special feature of the systems is the swivelling gauge head that can be easily moved up out of the extrusion line. The

measuring axes are arranged in such a way that the gauge is open at the bottom so that it prevents dirt and water from falling into the measuring area. The gauge heads of the Laser Series 2000 Profil have no moving parts, which results in an almost unlimited operating time. The ‘mean time between failures’ – the statistical average time after which a

device of that series shows a repairable defect – is 15 years. The devices also do not require calibration or routine maintenance.
