40khz Ultrasonic Transducer

Ultrasonic welding transducer is the key component of the whole ultrasonic system, and the transducer is used for converting high frequency and high voltage into mechanical kinetic energy. And it contains several piezoelectric ceramic discs sandwiched under pressure between two metal blocks. Between each disc is a thin metal plate, which forms the electrode. When a sinusoidal electrical signal is fed to the transducer via the electrodes, the discs expand and contract, producing axial vibrations Ultrasonic system contains three parts, ultrasonic generator, ultrasonic transducer and ultrasonic hoen, and the three parts is a complete ultrasound system.

Here are the features of the ultrasonic transducer:
Low resonant impedance, high mechanical quality factor.
High electro-acoustic conversion efficiency and large amplitude.
Low heating, large temperature range; Small performance drift, stable operation.
Good material, long service life.

Instruction of use:
The frequencies of the ultrasonic transducer, booster and horn must be matched with each other.
The frequencies of horn and booster should be lower than the frequency of transducer.
The connection surface must ensure vertical and flatness, and the connection torque must be appropriate.
The Welding of electrode plate should be reliable and covered with damping glue.
The operating temperature of the ultrasonic transducer should be lower than 60 °C, and the input power should be lower than the rated power.
