Applications
Automated high-performance inspection of submerged parts: metal plates, bars, pipes, composite materials, forged parts, etc.
Principle and 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.
General Characteristics
Acoustic
- Frequency from 500 kHz to 18 MHz
- Unlimited number of elements, typically 64 to 512
- Versatile, Dynamic, Accuracy or Hard face acoustic technology
- Reproducibility of the inspection through the homogeneity of performance between the elements of the same probe, and between different probes of the same type
Housing
- Ergonomic or basic housing
- High reliability over time thanks to a robust, watertight design, compatible with harsh industrial environments
Cable and connector
- Standard probes come with 3m cable, top or side output.
- Standard connectors are Ipex, hypertronix/FRB, ITT Canon, Tyco, Conec.
