Immersion transducers
Annular array Transducers
Applications
Thick parts inspection
Forged parts inspection
Principle & 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
