Steam generators tubes
Application example


Flexible circular phased array probes
Frequency from 8 to 15 MHz
Focused active area profile
Integrated multiplexor

Miniaturised probes for tubes inner diameter down to 12mm

10 MHz 80 elts circular phased array probe


High speed inspection with 360° electronic scanning

Manual or automated inspection
Contact with wedge

Circumferential cracks detection / axial angled emission


Inspection feasability thanks to circular array feasability and space saving
High resolution thanks to the frequency of 10 MHz

Wall thickness measurement (radial emission)
