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
