Applications
- Weld inspection
- Inspection of parts with complex geometry
- General NDT
Principle & Advantages
Matrix or 2D array transducers allow 3D beam
focusing and scanning, thus opening up new possibilities
- Control of the focal zone diameter in 3D, cylindrical beam
- Inspection of volumes from limited points of access
- Detection of defects that may have multiple, un-predetermined
orientations
General Characteristics
- Frequency from 500 kHz to 15 MHz
- Unlimited number of elements, typically 16 to 1024
- High S/N ratio and optimized pulse length thanks to acoustic
matching to wedge material (Rexolite, Plexiglas, PEI, etc)
- Reproducibility of the inspection through the homogeneity of
performance between the elements of the same probe, and between
different probes of the same type
- High reliability over time thanks to a robust, watertight design,
compatible with difficult industrial environments
