Inspection of thick parts, forged parts, complex interface parts and difficult materials (coarse grain, non homogeneous).
Principle and Advantages
The shaping of the active surface in a 2D array allows a 3D beam steering and 3D correction of the focus, which can compensate, for example, for the defocusing effect of a complex interface or an anisotropic material.
Furthermore, matrix immersion transducers, like annular arrays, allow electronic focusing at different depths.
- Frequency from 300 kHz to 20 MHz
- Number of elements: from 32 to 1024
- High sensitivity and signal-to-noise ratio, thanks to the acoustic matching to water allowing a very good transfer of acoustic energy
- Good axial resolution, and reduction of the unseen area below the surface thanks to a short pulse length
- High reliability over time thanks to a design that is watertight and resistant to corrosion, compatible with permanent immersion under 1 m of water
