[0002] An acoustic emission test sensor is a sensor used to monitor tiny cracks, damage or changes in structures or equipment. It identifies and locates problem areas by detecting sound waves or acoustic emissions generated in the material. In order to improve the accuracy of the detector during detection, an acoustic emission test sensor fixture is required.
