Turn-key CURTAIN machines integrate the M-Ray measurement technology for industrial use. The machines are tailored to perform measurements 24/7 as part of an industrial production line. Every CURTAIN O-frame and C-frame contains one or more M-Ray based measuring heads. These sensor heads measure the basis-weight, thickness or anomalies in various flat semi-finished products. Thanks to the nature of the M-Ray technology, the measurement standoff can be as high as 30 centimeters. The high standoff is useful for measuring thick materials and avoids scratches and defects on the material.

Instead of M-Ray based Marveloc sensor heads, Hammer-IMS allows for integrating other sensor types (see Sensor Fusion page) into a traveling or fixed CURTAIN system.

CURTAIN O-frame – Robust system for wide production lines

The CURTAIN O-frame machine, displayed on the right, consists of a rigid metal frame. The frame is mounted on accurate linear-drive mechanics, supporting high measurement reliability and robustness. The rigidity of the frame maintains high robustness even in harsh environments. The pure electronic nature of the M-Ray technology within this scanning frame is non-nuclear and non-radioactive. The traveling CURTAIN O-frame machine executes fast profile measurements, offering near-100% material coverage. The M-Rays’ high dynamics allow for high-standoff measurements that are fast and accurate. The width of an O-frame CURTAIN system can reach up to more than 5 meter.
