Ultrasonic Transducers Are Classified By Shape:

1: Inverted horn type transducer (Bi Nengxin type): large output amplitude, strong explosive power, suitable for high sound intensity, high power density occasions.
2: Cylindrical transducer (NTK type): stable output, high reliability, the widest application, suitable for most occasions.
3: Middle sandwich aluminum plate transducer: good heat dissipation, there are a variety of fixing methods.
4: Steel back cover transducer: large output power, high stability, suitable for high-power occasions.
Color classification of ceramic sheets for central piezo elements:
1: Yellow ceramic sheet: generally used for pulse type work
2: Gray ceramic sheet: generally used for pulse work
3: Black ceramic sheet: generally used for continuous work
