Ultrasonic circular plate series is used for ultrasonic cleaning transducer,ultrasonic
welding transducer ultrasonic polishing machine.
Application：
1. River、lake、depth
2. shoal detect
Features:
1) Miniature and current echo sounder
2) Minimum and the most inexpensive of the rungs of ship depth finder
transducer
3) Used for install inside and outside of miniature ship
