Detmaster PRT - Web Inspection SystemDetmaster PRT Web Inspection System is dedicated for detailed simultaneous on-line web inspection and quality control of coated multi-ply board products. The system detects coated multi-ply board surface and ply defects as well as measures surface quality parameters such as gloss, brightness, gloss-mottling, white top mottling and formation. The detector beams of the Detmaster PRT system dedicated for surface defect detection are always installed against the roll surface in order to realise stable measurement conditions where web bounce and undulation are completely eliminated. As a result of this necessary arrangement the Detmaster PRT system is able to detect extremely low contrast surface defects such as blade streaks, nozzle streaks, butterflies, coating skips, etc. 
The detector beams of the Detmaster PRT system dedicated for ply defect detection are always installed on an open draw where detector beam receives transmission light through the web from an integrated illumination beam. This arrangement enables e.g. detection of defects such as core ply hole and edge crack as well measurement of quality parameter formation. Furthermore, the Detmaster technology enables on an open draw with a single detector beam solution integrated with a transmission illumination source on the other side of the web the detection of tiny holes (> 0.1 mm2), edge cracks and even core ply holes as well as formation measurement through all plies of the web. All this is realised with powerful infra-red transmission illumination sources utilising 2 illumination angles and 2 frequencies.

SR-Instruments Infoboard 18.1.2013Before the end of last quarter of 2012, SR-Instruments was awarded some repeat orders by it’s existing customers. :
2.7.2012 Zhangjiagang Yangzi River Cold Rolled Sheet Company in China has recently acquired two pieces of SR-Instruments Oy's Detmaster 1400 MPH Pinhole Detection Systems for new Electrolytic Tin Plating Line and Continuous Annealing Line. The concerned Detmaster MPH systems are able to simultaneously detect tiny edge cracks and pinholes from size 10 um up to large holes. With these features Detmaster MPH systems guarantee the efficiency and the quality assurance at the new Electrolytic Tin Plating and Continuous Annealing Lines of the Works. 16.4.2012 Erdemir Works in Eregli, Turkey has recently acquired SR-Instruments Oy's Detmaster 1300 MPH Pinhole Detection System for Electrolytic Tin Plating Line to replace an obsolete pinhole gauge. The concerned Detmaster MPH system is able to simultaneously detect tiny edge cracks and pinholes from size 5 um up to large holes. With these features Detmaster MPH system guarantees the efficiency and the quality assurance at the Electrolytic Tin Plating Line of Erdemir Works. Archive...
