Functional Structure Of Ultrasonic Transducer

The ultrasonic transducer includes a housing, a matching layer, i.e., an acoustic window, a piezoelectric ceramic disc transducer, a backing, and a lead-out cable. It is characterized in that it also includes a Cymbal array receiver, which is composed of a lead-out cable, 8 to 16 Cymbal transducers, a metal ring, and a rubber gasket; the Cymbal array receiver is located on the disc piezoelectric transducer 3; the piezoelectric ceramic disc transducer is used as a basic ultrasonic transducer, which transmits and receives ultrasonic signals; the Cymbal array receiver is located on the disc piezoelectric transducer as an ultrasonic receiver, which is used to receive Doppler echo signals outside the frequency band of the disc transducer.
It is mainly applicable to ultrasonic plastic welding machines, ultrasonic metal welding machines, ultrasonic cleaning machines, gas phase machines, trichlorine machines, etc.
