Electromagnetic and Acoustic Emission Signals Real-Time Measurement, Processing and Data Evaluation
Tomáš Trčka, Pavel Tofel, Pavel Koktavý · Key engineering materials · 2011
This paper describes our new improved set-up for EME and AE signals measurement and includes some experimental results. This new measurement system is based on the PXI platform, which is one of the most extended modular platforms for measurement and automation systems. The complex program package in the LabVIEW graphical programming environment was developed for the continual multi-channel EME and AE signals measurement, real time processing and evaluation. It offers the possibility to observe the stressed materials response to applied mechanical load in real time.
