Hydrophone Transducer Application:
The hydrophone is made with a piezoelectric ceramic cylinder. The piezo element offers a receive sensitivity of -202.5 dB over a broad working bandwidth of 1 Hz - 100 kHz. hydrophones are designed specifically to maintain accuracy with large changes in both temperature and pressure that are common to deep ocean applications. It offers a remarkably compact form factor relative to other hydrophones that is ideal for systems in which space is limited. Mounting points, connectors, and other parameters can all be customized.
