Primary pump thermal barrier
Thermal barrier of primary pump inspection

Application example

Probes

Special curved linear array probes with soft wedge
Aspherical focusing to focus through a toric interface

Coupling with water film
Custom housing for probe holder

 

Technique

Pulse echo technique

2 MHz 16elts Curved linear phased array probes with integrated soft wedge

Benefits

High sensitivity to work through a 200 mm sound path in austenitic steel
High lateral resolution thanks to aspherical focusing

Active area geometry
