200kHz Transmitting Underwater Acoustic Transducer for Depth Measurement
Product Description
200kHz Transmitting Underwater Acoustic Transducer for Depth Measurement
Introduction:
This type of single-frequency directional transducer is made of high-quality components, with a centrally symmetrical natural single beam, the main beam is conical, with excellent performance and high reliability. It is suitable for landform survey, bottom depth survey and fish detection of inland rivers, lakes and shallow waters, and can be used as underwater accessories of related underwater acoustic detection instruments.
