產(chǎn)品簡介

大鍛件相控陣檢測 環(huán)形相控陣探頭 相控陣探頭

詳細介紹

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
