Digital Wave Corporation, the originators of Modal Acoustic Emission (MAE), brings you the B225.5 sensor.  With the sensitivity of a resonant transducer (nominal +53 dB [ref. 1V/µm] @ 150 kHz), and a flat frequency response from 50 – 400 kHz, the B225.5 sensor is an ideal candidate for the MAE testing of relatively thick structures (e.g., thick walled high pressure vessels, A.O. Smith pressure vessels, thick laminated structures, etc).  The B225.5’s increased aperture, coupled with the superior output of the piezoelectric crystal, make it the ideal sensor for testing situations where low energy events (such as real crack growth in metallic structures) must be reliably detected.  Suitable applications for the B225.5 sensor range from metallic fatigue test monitoring through MAE testing of composite overwrapped pressure vessels.
