产品简介

大锻件相控阵检测环形相控阵探头相控阵探头

详细介绍

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:

Freq. (MHz)	Nb elts	Active diameter (mm)	Housing size diameter x height (mm)*
10	8	18	25 x 40
10	16	25	35 x 40
10	32	35	45 x 45
5	8	35	45 x 40
