INTRODUCTION
The TDH-62 deep-sea spherical hydrophone adopts a high-strength spherical structure design, specially designed for extreme high-pressure environments in the deep sea. It has passed the 60MPa (about 6000 meters working depth) pressure test certification and has excellent reliability and durability. This product uses high-performance spherical piezoelectric ceramic components and can be paired with a 10-30dB preamplifier to cover a wide frequency range of 10Hz-200kHz, achieving 360 ° omnidirectional acoustic response. TDH-62 has the characteristics of low background noise, compressive stability,
and full frequency sensitivity, making it an ideal acoustic detection device for deep-sea resource exploration, marine environment monitoring, underwater acoustic communication, and other fields.
Main Application Scenarios
- Hydrophones of sonar buoys
- Transducers for underwater positioning
- Reference hydrophones, noise measurement
- Measurement of ultrasonic cavitation noise
- Passive acoustic monitoring
- Forming hydrophone arrays or vector
- Marine bio-acoustics
