超声波弯曲振动传感器(转化器)

ultrasonic Bending vibration transducer(converter),Application of ultrasonic technology in some applications, such as turning ultrasound, ultrasound to eliminate foam and dust, such as the use of bending vibration system will be more convenient and effective. Currently There are two main methods for Bending vibration generated: one is the sandwich structure of the bending vibration transducer, such as a group of semi-circular piezoelectric ceramic in between the two metal bar, appropriate arrangements for the direction of its polarization, and through screw consisting of pre-stress imposed constitute the bending vibration transducer. This transducer structure is simple structure and can bear a greater power. Another is the use of vibration mode conversion to produce bending vibration, such as using vertical vibration transducer to stimulate disk, plate or rod bending vibration generated. Past, using a variety of bending vibration disk or plate, Characterized by high radiation efficiency. Turning in ultrasound applications, new developments in the bending vibration transducer is more promising. sandwich-type bending vibration transducer of the structure similar to longitudinal vibration transducer. And longitudinal vibration of sandwich piezoelectric transducers the difference is here is a semi-circular piezoelectric piece, and the formation of a circular piece of the two semi-circular polarization opposite direction, composed of four semi-circular piece. When the drive voltage imposed on the transducer, at the voltage positive half-cycle, on a half-chip piezoelectric ceramics expansion, and contraction of the second half of chip, the negative half-cycle when the opposite is true. At the role of alternating voltage, the transducer do flexural vibration. My company as high-power ultrasonic transducer of the leading manufacturers of top-quality ultrasound transducer is where our competitive edge, providing customers with appropriate, high-quality transducer is also our responsibility. We already have 20k vertical bending vibration transducer, 35k disc bending vibration system, and so on. If customers have special needs, we can also provide program design, principles of testing, such as a prototype package of trial solutions.
