Non Destructive Testing EncyclopediaNDT is an acronym for Non Destructive Testing. It is also refered to as Non Destructive Inspection (NDI), or Non Destructive Evaluation (NDE). NDT is exactly what its name implies, testing in which the part or material being evaluated is neither damaged nor destroyed. NDT covers a broad range of testing methods, including magnetic particle, liquid penetrant, ultrasonics, visual inspection and vibration analysis to name a few.

Latest News from the NDT world: 94Advantest brings terahertz material testing to commercial realm
Added:20/10/2009 For a long time, researchers have worked on techniques using the terahertz frequency range for material test applications. Japanese test system vendor Advantest now brings these waves to practical applications. Full Story...78Digital X-ray Panel features 8 x 10 in. active areaAdded:20/10/2009 Supporting x-ray energies up to 160 kVp, SkiaGraph10 EV enables medical radiologists and industrial inspectors to image proportionally larger subjects in field where images cannot be reduced by optical coupling. Digital CMOS x-ray camera, capable of real-time imaging at up to 1.4 fps (5.3 fps in binned mode), delivers 12- or 14-bit digital contrast resolution and 5 lp/mm spatial resolution. Graphite cover protects sensor from accidental damage as well as ambient light.

Full Story...185Development of an Underwater Radiography Inspection System for Inspection of Flexible RisersAdded:04/08/2009 Greek team produce prototype robot crawler for deployment of equipment for inspection of underwater structure. Zenon, a Robotics manufacturer and developer based in Athens, Greece, has developed a new prototype robot crawler for deployment of the inspection technology on man made underwater structure. Specifically the robot has been developed to crawl along the external surface of flexible risers. It moves along and around the riser using an inch-worm type motion. Full Story...126Drop Test Fixture automates quality testing of small partsAdded:04/08/2009 Utilizing Resonant Acoustic Method, Model NDT-DTF automates quality testing of parts as small as ball bearings or small electronic connectors. Parts are automatically sorted via PLC-controlled stepper motor. No part preparation is needed for testing and no human interpretation is necessary. Offering speeds of 1 part/sec and providing pass/fail result, fixture automates with bowl feeders or vibratory tables and is instrumented with laboratory-grade force sensor, microphone, and DSP analyzer.

The cameras build upon a tiled configuration of RadEye100 very large area (VLA) CMOS image sensors to achieve a total active sensing area of 8 x 8 in. (20 x 20 cm), which is sufficient to capture most objects of interest in a single frame yet small enough to maintain ease-of-use in setup and portability. Real-time imaging occurs at up to 1.4 frames/s (5.3 frames/s in binned mode). Pixel size is 96 µm (5 lp/mm spatial resolution), with more than 4 million pixels overall.
