Acoustic emission (AE) refers to the phenomenon that a material or structure is deformed or broken by external force and internal force, and the phenomenon of releasing strain energy in the form of elastic wave is called acoustic emission The position (defect) at which the elastic wave is emitted is called an acoustic emission source However, the acoustic emission signal intensity of many materials is very weak, and the human ear cannot directly hear it, and it needs to be detected by sensitive electronic instruments Our company HX-AE-01A Acoustic Emission Monitor comes standard with 12 channels of data acquisition The number of channels can be customized It can realize continuous monitoring of components for a long time, high-speed acquisition, storage and feature parameter extraction of real-time acoustic emission waveform data, and low noise Strong anti-interference ability
