Acoustic emission (AE) is a phenomenon in which the sound generated when an object deforms or fractures is emitted as elastic waves.
AE sensors can detect/predict defects and fractures in materials and structures by capturing the behavior of such elastic wave generation.

AE sensors capture the unheard call of products that are beyond the reach of the human senses.
AE sensors are essential in many fields, from product quality inspection to safety monitoring of large structures.

This section introduces measurement system configurations using AE sensors with/without a built-in amplifier.

FUJI CERAMICS is the only company in Japan that applies absolute sensitivity calibration methods (reciprocity calibration method and sound pressure method).
