New ULO (Ultra-light O-frame) scanner from Scantech Americas, Gaithersburg, Md., features a compact frame and x-ray sensor and a host of energy-saving features. Unlike competing products, ULO sensors do not require hazardous radioactive sources such as gamma backscatter, and are manufactured with fewer
components, less cabling, and more advanced electronics. The end result is reportedly a more robust system with production and cost-saving benefits for film, sheet, and laminating. The scanner is being unveiled at this month’s NPE2012 show in Orlando.
Measurement sensors are mounted on the sides of the scanning head to avoid the risk of dust or grease falling onto the web. The drive system is shielded by the frame and associated covers. If needed, the inside of the frame can be lightly air-pressurized to prevent entry of dust and fibers. This feature enables the scanner to be used in ultraclean environments. For more complex applications such as extrusion coating,
multiple scanners can be linked in a daisy chain to share data. As an added bonus, the ULO is adaptable to any electrical power supply, as its power consumption is below 250W (less than a small household appliance).
The scanner can be mounted on a production line from below, from above, or at an angle up to 30° from
horizontal. Sizes range up to 5 meters wide. For up to 2 meters, scanner widths are available in 250-mm increments. For webs wider than 2 m, scanners come in 500-mm increments.
