20kHz~30kHz High Frequency Hydrophone Transponder Transducer
Product Description
20kHz~30kHz High Frequency Hydrophone Transponder Transducer
The high-frequency transponder transducer adopts advanced half-space transmit-receive technology with excellent beam directivity, which effectively improves the signal-to-noise ratio (SNR) and operating range. Its pressure-resistant structural design guarantees stable operation at a maximum working depth of 2000 meters. Featuring high precision and low power consumption, it is an ideal option for underwater precise positioning, communication and surveying applications.
