The ultrasonic transducer includes a housing
(1) and a matching layer, that is, the acoustic window.
(2) piezoelectric ceramic disc transducer
(4) lead out cable
(5) it is also characterized by the Cymbal array receiver, which is derived from the cable.
(6) 8~16 Cymbal transducers
(7) metal rings
(8) and rubber washer.
(9) Composition; Cymbal array receivers are located above disc piezoelectric transducers 3; piezoelectric ceramic disc transducers are used as basic ultrasonic transducers for transmitting and receiving ultrasonic signals; Cymbal array receivers are located above disc piezoelectric transducers as ultrasonic receivers for receiving the frequency bands of disc transducers The external Doppler echo signal.
