Applications
- Thick parts inspection
- Forged parts inspection
Principle and Advantages
Using electronic focusing, the focusing distance and the depth of field can be changed, this enabling thick parts to be inspected with excellent lateral resolution over a large range of depth, without changing the transducer.
General Characteristics
- Frequency from 300 kHz to 20 MHz
- 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
