Underwater accoustic element
Application Theory: The measurement machine of an underwater ultrasonic wave(sonar) is known for the purpose of navigation. The ultrasonic wave pulse is radiated in the sea, and the reflection wave from a target object is detected, and this is presence, measures the distance distinguishes the direction, and a kind of radar of the object. Piezocermic applied for underwater acoustic transducers contain both transmitters and receivers and use distance and directional data for communication, marine research ,undersea mapping and navigation.
Designs Shape: Hemisphere, Bowl, Segment, Tube, Block
