These pressures cause the fabric to … WebActive sonar transducers emit an acoustic signal or pulse of sound into the water. If an object is in the path of the sound pulse, the sound bounces off the object and returns an “echo” to the sonar transducer. If the transducer is equipped with the ability to receive signals, it measures the strength of the signal.

WebSep 20, 2024 · The echo sounder system comprises four components, namely a transmitter, a receiver, a transducer and a display unit. The transmitter creates a short pulse of AC current which it passes to the transducer which is situated at the bottom of the ship. WebApr 10, 2024 · The echo sounder is an electronic device that uses sound waves to detect objects under the water. This device is commonly used by fishermen to find fish. The echo sounder sends out a pulse of sound and then listens for the echo of that pulse. The time it takes for the echo to return tells the fisherman how deep the object is.
