Contactless Shape Monitor

The Contactless Shape Monitor is a cutting-edge flatness measurement system designed to meet the growing demand for high-quality rolled strips in the metals industry. This innovative solution addresses the challenges of traditional contact-based systems by providing accurate, contact-free measurements, ensuring high precision and minimal risk of damage to both the strip and sensors.

The Contactless Shape Monitor employs advanced technology to measure strip flatness without physical contact, utilizing eddy current sensors and a unique strip oscillation mechanism to accurately determine strip tension distribution. By eliminating contact, the system avoids sensor wear and strip damage, ensuring reliable and precise measurements even in harsh industrial environments. Operating independently of rolling speed, the monitor provides up to ten measurements per second, enabling immediate correction of flatness errors and significantly reducing scrap, particularly in reversing cold mills.

Unlike traditional systems that rely on distributed sampling, the Contactless Shape Monitor captures consistent measurements from all sensors simultaneously, enhancing data quality by eliminating short-term tension variations. The system automatically adapts the excitation force to maintain optimal sensor performance across various strip dimensions and tensions, ensuring precise measurements regardless of material thickness. With no physical contact, the monitor remains unaffected by disturbances from bending forces, guaranteeing accurate flatness readings.
