Applications
Applications demanding good resolution at medium depth range, with limited 3D steering
- Weld inspection
- Inspection of parts with complex geometry
- General NDT
For larger 3D beam steering capability, see high density matrix arrays
For long range or high resolution inspection, see high resolution matrix arrays
Principle and 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 orientation
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 coustic 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
