INSPECTION SYSTEM SONOAIR

Advantages

  • Air-coupled, contactless, couplant free
  • Inspection of highly attenuating materials
  • High resolution due to the use of focusing transducers

 

Applications

  • Interface detection
  • Bond inspection and homogeneity analysis
  • Delamination testing etc.

Already during the material development of modern composite materials such as glass or carbon fiber reinforced plastics (GFRP, CFRP) and ceramics it is necessary to detect internal structures and discontinuities fast and reliably.

Research institutes, industrial development laboratories and quality assurance departments of production facilities highly appreciate a contactless, high resolution inspection. The performance of the transmitter receiver system is very important to penetrate these highly attenuating materials. The ultrasonic transducers, the scanning area and the software can be adapted to the specific geometry and material composition of the test object.

These high requirements can be fulfilled with the new and modular SONOAIR inspection system for laboratory and quality assurance applications.
