Annular phased array probes

Electronic focusing

Principle

Focusing depth can be electronically selected

More details about phased array principle here >>

Adapted to all coupling methods
Typical work in pulse echo mode

Applications

Application requiring variable focus distance, for example multi-zone inspection of plates, billet or other pieces

Advantages

Reduction of the number of probes
Inspection depth variation speed (tuning, calibration)

Typical configurations
