High Quality Yellow Ceramic 40kHz 500W Ultrasonic Piezoelectric Welding Transducer

Specification:

Description:

The core of the ultrasonic transducer is the piezoelectric ceramic sheet. As is true in many other applications for piezo-electric materials, an assembly of multiple ceramic elements offers considerable performance and production advantages in ultrasonic transducer, relative to a single ceramic element. In order to provide the most efficient operation, simplify manufacturing, and reduce costs, more complex transducers intended for ultrasonic power applications usually are a composite of a piezoelectric ceramic center (multiple thin rings or disks of ceramic, for example), encompassed by metallic end or top and bottom parts. Under no liquid load, the mechanical quality factor, Qm , for a well-designed composite transducer will be greater than the correspond¬ing value for an equivalent single piece ceramic transducer, and efficient heat conduction by the metallic portions will ensure a lower operating temperature in the ceramic portion of the transducer. The coupling factor, k, will approach that for a single-piece ceramic transducer.

Competitive Advantage:

1. Imported ceramic discs and superior aluminum raw materials

2. Once assembled, the transducers are aged before testing and final assembly. The properties of piezoelectric materials can change with time and pressure, so a bit of time on the shelf prior to testing will identify nonconforming material

3. One by one testing to ensure that each transducer performance are excellent

4. In good heat resistance, can be used in a wide range of temperature with long life and high reliability
