FLEXIBLE ULTRASONIC ARRAYS

 

Our SonoFlexTM array units can be dry-coupled to either flat or contoured objects for rapid inspection.  Images are produced by electronically scanning the array.  Image formats include: 1) C-Scans (plan views) of either amplitude or thickness, and 2) B-Scans (elevation views).   Potential applications include:

      • Composites Inspection:
        • Delamination
        • Matrix cracking
        • General impact damage
        • Ply count and sheet thickness
      • Detection of thickness, bond quality and corrosion in metals
      • Erosion-corrosion imaging in piping

The arrays shown in our web page banner (above) are expanded below for greater clarity.  Also shown are a typical B-Scan and C-Scan.   Field Applications and  System Details sections follow.
