Detmaster MT - Hole and Edge Crack Detection System

Detmaster MT system enables accurate hole and edge crack detection as well as an optional width measurement feature.

The primary advantages of the Detmaster MT system compared to the traditional hole gauges are:

• Detmaster MT system measures holes from size 200 µm up to large holes with only one measurement system.
• Detmaster MT system is able to detect additionally edge cracks from size 200 µm up.
• Detmaster MT system doesn't need any mechanical edge following units because it includes active optical edge detection method.
• Ambient light doesn't interfere to the operation of the Detmaster MT system because it comprises frequency modulated light sources.
• Detmaster MT system includes LED light sources, which have average lifetime of 290 years with constant light intensity.
• Detmaster MT system doesn't include any component, which needs to be changed frequently. It is practically maintenance free system.
• Detmaster MT system informs the position of each hole in MD (machine direction) with accuracy of 1 mm and in CD (cross direction) with an accuracy of 8 mm.
• Detmaster MT system enables categorisation of different size holes and edge cracks to own size classes. The operator of the Detmaster MT system may determine the range for each hole and edge crack size class.
• Detmaster MT system provides on a graphical user interface a coil report, which indicates location and size of each individual hole and edge crack in a concerned coil.
• Detmaster MT system can be pulled out of the line for verification and maintenance purposes with a roll out system automatically or manually without disturbing running of the process line.
• Detmaster MT system comprises dynamic verification tools for easy system performance verification = motor controlled rotating disc including certified hole samples simulating the actual production line speed.
• Detmaster MT system measures optionally the width of the strip with an accuracy of ± 1 mm.
• Detmaster MT system measures accurately holes and edge cracks with line speeds up to 2000 m/min.
