PZT4 Low Frequency 20KHZ Piezoelectric Ultrasonic Washer Transducer Output Power 50W With CE Warranty 1Year 

Ultrasonic transducer:

The so-called directivity factor refers to the sound pressure of the main axis of the emitted sound beam, and the mean square sound pressure of a certain frequency away from a certain point of the transmitting ultrasonic transducer is the same as a point on the spherical surface concentric with the transducer and the transducer. The ratio of the mean squared sound pressure of the frequency. For the receiving ultrasonic transducer, the horn manufacturer indicates that the ratio of the square of the electromotive force generated by the sound field generated by the sound wave of a certain frequency along the main axis of the transducer is the square of the electromotive force generated by the diffused sound field with the same frequency and the same square root sound pressure.
