Linear arrays

High penetration / Wide scan linear arrays

Applications

Automated high-performance inspection of submerged parts: metal plates, bars, pipes, composite materials, forged parts, etc.

Principle & Advantages

The scanned length (L) is maximised by combining a large number 
of elements (typically between 64 to 512) with the widest possible 
inter-element pitch (p).

Electronic focusing can be combined with scanning, for example, to inspect at different depths. In general, electronic deflection is little used for this type of application.

• Inspection time is reduced through the high speed of the electronic scanning combined with a large scanning width.
• The scanning mechanism is simplified.

Standard Configurations:

General Characteristics

• Frequency from 300 kHz to 20 MHz
• Unlimited number of elements, typically from 64 to 512
• Versatile, Dynamic, Accuracy or Hard face acoustic technology
• Ergonomic or basic housing
• Good axial resolution and reduction of the unseen area beneath the surface thanks to a short pulse length
• Reproducibility of the inspection because of the homogeneity of the elements of the same probe and the different probes of the same type
• High reliability over time thanks to a design that is watertight and resistant to corrosion, compatible with permanent immersion under 1m of water

Options

• Pre-focused active area (see below)
• Captive screws of lateral flanges for wedge attachment
• Integrated wedge
• Housing adapted to the probe holder
• Low profile and side cable for wheel probe
• Halogen-free for nuclear environments
• Customized cabling
• Adaptation to a particular environment (temperature, pressure, radiation, chemical compatibility)
