Product details

Product introduction

The HTD-63 Spherical Hydrophone offers an omnidirectional response up to 135kHz, combined with excellent acoustic characteristics such as low noise and durability. This makes it highly suitable for a wide range of oceanographic applications.

The HTD-63 Spherical Hydrophone can incorporate a built-in preamplifier, which not only amplifies the signal but also allows for normal use with extension cables without sensitivity loss. A built-in filter increases the signal-to-noise ratio by removing unwanted noise signals, thereby preventing signal saturation.

Main application scenarios

(1) Hydrophone for sonobuoys
(2) Transducer for underwater positioning
(3) Reference hydrophone, noise measurement
(4) Measuring ultrasonic cavitation noise
(5) Passive Acoustic Monitoring (PAM)
(6) Forming hydrophone arrays or vector sensor arrays
(7) Marine bioacoustics research
