Description:
The converter is aptly named because it receives electrical energy from the power supply and converts it into mechanical vibrations. Branson CJ-20 converter (101-135-059) replacement used in all 20KHz 2000, 2000X and DCX series IW, actuator and assembly stand systems that delivers rugged quality and superior value.
Ultrasonic transducer is a device that converts electrical energy into mechanical energy. The device that converts electrical energy and acoustic energy by piezoelectric effect is called piezoelectric transducer. It consists of central piezoelectric ceramic component, front and rear metal cover, prestressing. The screw, the electrode piece and the insulating tube are composed. Depending on the design of the different structures, their form and performance are also greatly affected.

Ultrasonic technology is a widely used non-destructive testing technology based on acoustic theory and is used in electronics, communications, medicine, biology and physics. In modern detection technology, the transducers developed by ultrasonic technology are getting more and more attention because of their high sensitivity and high precision.
Transducers commonly used in the detection process are: piezoelectric transducers, magnetostrictive transducers, electromagnetic transducers and laser transducers. The most commonly used is a piezoelectric transducer, whose core component is a piezoelectric wafer. The piezoelectric wafer can be deformed under the action of pressure, resulting in polarization of the wafer itself, and positive and negative bound charges appear on the surface of the wafer, and this effect is a piezoelectric effect. Moreover, the piezoelectric effect is reversible, that is, deformation occurs after a voltage is applied to the wafer. In the detection process, the ultrasonic effect can be generated by the inverse piezoelectric effect of the ultrasonic probe, and the piezoelectric effect is used to achieve the purpose of receiving the ultrasonic wave.
