ABB’s HPINet WIS Dirt Count system provides full web width inspection, imaging and identification in real-time to improve pulp quality and production yield, as well as customer satisfaction. Accurate dirt detection, imaging and classification all play a crucial role in quality control and process improvement for pulp production. ABB’s Dirt Count web imaging system meets today’s demands for increased quality and runnability, with 100% inspection of pulp and reduced customer claims.

Using high resolution, CMOS (complementary metal-oxide semiconductor) digital cameras together with advanced machine vision tools to improve performance, the Dirt Count System provides an exceptional level of real-time defect detection on the fastest and widest width modern paper machines. Real-time detection of dirt and shives in pulp allows operators to take corrective actions earlier, resulting in improved production yield and quality and reduced customer claims.

Dirt detection and analysis are performed by specialized, high-speed FPGA (field-programmable gate array) devices. Automated detection and counting yields consistent and repeatable results leading to improved grading of production. Defects as small as 0.02 mm2 (less than half of the width of a human hair) may be detected which enables ABB’s Dirt Count System to fully comply with all defect size classifications in the ISO/TAPPI/ANSI standards.

ABB is a pioneering technology leader in electrification products, robotics and motion, industrial automation and power grids, serving customers in utilities, industry and transport & infrastructure globally.
