Acoustic Emission (AE) is the most flexible NDT method.

Normally used for screening of large structures, A³ Monitoring utilizes AE for monitoring of structures. AE can be used for monitoring the ‘acoustic activity’ generated from noise sources such as cracks or leaks in pipelines or pressure equipments or to monitor civil infrastructures such as bridges.


A³ Monitoring uses its mechanical and communication design powered with Vallen sensors. Vallen is A³ Monitoring AE technology partner and the largest AE technology developer and manufacturer in Europe.

A³ Monitoring software capabilities are essential to maximize the benefit of Acoustic Emission monitoring.
