The converters corresponding to your INVOICE NO. HS2015021 work very well. We would like to order more

—— Peter

I'm very happy with your good communication skills as well as follow up and good deal. I will definitely inform you my further program for further coo

—— Vinay

We tested it and it worked.  I will let you know about future purchases soon.

—— Alvin

The Structure Principle Of Ultrasonic Transducer

 

The ultrasonic transducer is the heart of the ultrasonic welding machine, just like the engine of a car, which converts the high-frequency electrical energy or magnetic energy output by the ultrasonic generator into mechanical vibrations of the same frequency.

 

It mainly consists of shell, acoustic window (matching layer), piezoelectric ceramic disc transducer, backing, outgoing cable, receiver and so on.

 

Among them, the piezoelectric ceramic disc transducer plays the same role as the general transducer, and is mainly used to transmit and receive ultrasonic waves; and above the piezoelectric ceramic disc transducer is the receiver, which is mainly driven by the lead-out cable. , transducer, metal ring and rubber gasket, used as an ultrasonic receiver to receive the Doppler callback signal generated outside the frequency band of the piezoelectric ceramic disc transducer.

 

It is a piezoelectric ceramic that resonates at the ultrasonic frequency, and the electrical signal is converted into mechanical vibration by the piezoelectric effect of the material. Ultrasonic transducer is an energy conversion device. Its function is to convert the input electrical power into mechanical power (ie, ultrasonic waves) and then transmit it out. It consumes a small part of the power itself. Types: Can be divided into piezoelectric transducers, sandwich transducers, column transducers, inverted horn transducers, etc.
