Amsterdam Technology bv has combined the quality of ultrasonic immersion scanning systems with the practical benefits of handheld instruments by developing a new strongly miniaturisd instrument .

First in the world Amsterdam Technology bv introduces the “Miniscanner” a handheld high resolution ultrasonic scanning system with full A-scan and C-scan presentations.The inspection instrument, with software based meets the performance of an immersion tank scanning system when a small area is to be inspected. It consists of a small sized handheld scanner with a portable ultrasonic control unit, containing an 8" touch screen panel.

The handheld scanner can simply be placed on a test object, i.e. a spot weld and the A-scan is displayed. Press the scan button and after a few seconds a complete C-scan is presented on screen.

MINISCANNER CAPABILITIES
    Shape Of Spot Weld Nugget
    Nugget Diameter Measurement
    Thickness of the Spot-Weld
    Weld plate Thickness Measurement
    Size of the Defect
    Depth of the Defect
    Width of the Weld Line etc

Patented Magneto-Optic Imager (MOI) systems feature a nondestructive evaluation (NDE) process that is highly effective at detecting cracks and corrosion in aircraft skin and around rivets. Using eddy current excitation, MOI’s rapid scanning and data processing speed enables aircraft operators to achieve greater flaw detail and greatly reduce downtime for required inspections

MOI is also highly valuable when used for industrial NDI of metallic structures that are flat or have some shallow curvature, that require high safety levels to be maintained.

 MOI Advantages

    Calibration not required
    Significant time savings in inspections
    Minimal operator training required
    Paint stripping not required
    Rapid real-time inspection of large areas
    Demonstrated 10 times faster than eddy current probes alone
    Select from one of three 308 systems designed to comply with specific aircraft manufacturer’s notices as well as FAA Aging Aircraft Standard Rules (AASR) inspection compliance.

Rivets or holes show as smooth circular forms. In the MOI image shown above there are two rivets with no cracks and two rivets with cracks. Cracks can be seen around the complete circumference of the rivet site in one pass of the imager over the aircraft. Surface images are viewed using higher frequencies (50 - 100 kHz). To penetrate more deeply into the metal, the inspector must lower the frequency level on the power unit. Images are viewed in the PVS headset by the inspector, or on an optional outside monitor (NTSC or PAL compatible) that connects to the control unit.

This is an MOI 308/3 image of corrosion on the aircraft bellyskin. Frequency has been set to 5 kHz. Corrosion images are irregular in shape and show as dark shadows between rivets or around rivet sites. In this sample there is a chem-milled step which shows as a dark line shape to the right of the corroded area. Since the MOI is an area inspection device instead of a point by point device (such as an eddy current probe) the MOI can rapidly locate corroded areas.

This is a third layer crack image that is 0.084" from the surface. The frequency has been set to 5 kHz resulting in a more diffuse image. Since surface cracks will also be visible, it is important that the inspector perform a high frequency scan first and mark surface defects. When the frequency is lowered, new crack images are subsurface defects.
