- Electromagnetic acoustic transducer(EMAT) is a new ultrasonic transmitting and receiving device.
- The relative separation of the vessel and ROV is measured with an acoustic transducer and transponder.
- In this paper, a new acoustic transducer of SBT sonic logging tool is introduced.
- The increasing use of electromagnetic acoustic transducer(EMAT)in NDT has become possible due to its a good many merits.
- The purpose of this work is to use a single acoustic transducer to perform as a command master, which acts as several signal sources, to control the remote operation vehicle.
