THE CRx Flex is the latest addition to the suite of digital radiography conversion options from GE Sensing & Inspection Technologies. Combining flexibility, versatility and reliability with wide latitude and high image quality, the CRx Flex will find applications in flaw detection in welds and cast parts, and in the inspection of piping for erosion/corrosion. The scanner can be used with either isotopes or X-ray sources, and is designed for the rigorous radiographic inspection requirements encountered in the oil and gas, aerospace, power generation,

automotive and military sectors. Unlike competitive phosphor scanners, it can be used either with hard cassettes, in which the phosphor imaging plate never leaves the cassette, or it can scan any size of phosphor screen up to 14"x17", and any shape can be accommodated. These individual imaging plates can be exposed using a soft, flexible cassette (with or without lead) before scanning. Productivity is also improved due to the wide dynamic range and high signal-to- noise ratio of the scanner.

This combination allows a broad range of thicknesses to be inspected in a single exposure, resulting in streamlined procedure development, less exposures/retakes and increased component throughput. The CRx Flex also has the ability to produce a high level of image quality due to its specially designed optics, its true square 50-micron pixel size and its 30-micron laser spot size. This precise scanning resolution allows the CRx Flex to qualify for the IP Class Special/60 (ASTM E2446-05) and IP Class 1/60 (EN 14784-1). The robust CRx Flex has a small tabletop footprint and is designed to provide reliable operation within the harshest of NDT environments, offering long mean- time-between-failures and maintenance. To further minimise downtime, its internal modular construction allows easy and rapid field serviceability. Its horizontal transport system extends the life of the imaging plates, as it has little or no direct contact with the imaging plate during the scanning process. This eliminates the possibility of plate damage during the scan process and reduces general wear and tear. Juan Mario Gomez, product general manager, radiography, commented: “By combining the operational features of CRx Flex with our Rhythm software platform, customers can now acquire, review, report and archive inspection data. They can also enjoy the benefits of data sharing and image enhancement, which allow significant improvements in productivity and faster identification of defect indications . ” GE Sensing & Inspection Technologies – UK Fax : +44 1727 795400 Email : david.jervis@ge.com Website : www.gesensinginspection.com
