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

Standard Configurations:

*Indicative values

• Spherical or bifocal mechanical pre-focusing
• Housing adapted to the probe holder
• Halogen-free for nuclear environments
• Customized cabling
• Adaptation to a particular environment (temperature, pressure, radiation, chemical compatibility).
