摘要:
A pressure pulse sensor, and, in particular, a hydrophone, provide enhanced functionality and convenience in detecting pressure pulses. The hydrophone (30) includes a stack (34) of disc-shaped lead titanate piezoelectric crystals (32) enclosed within an epoxy membrane (38) and a mounting portion (44) which is aligned with a center of mass (48) of the crystal stack (34).
