SinoTD20 Communication Transducer
1. Introduction (SinoTD20 Communication Transducer)
SinoTD20 is a pulsed ultrasonic transducer designed for underwater acoustic applications, operating at a frequency of 20 kHz. It supports multiple pulse signal types (such as sine wave, Chirp, PSK, FSK, etc.), making it suitable for underwater acoustic systems requiring high-power pulse output. The transducer features omnidirectional horizontal directivity (360°) and 90° vertical directivity at resonance frequency. Its design takes into account power limitations, thermal management and various mounting methods, making it suitable for complex underwater environments.
