Ultrasonic impedance analyzer application
Application areas:
This instrument is suitable for measuring various ultrasonic devices, including: ultrasonic transducers, ultrasonic horns, ultrasonic molds (tool heads), independent piezoelectric ceramics, transducers, ultrasonic cleaning machines, ultrasonic plastic welders, underwater acoustics , Magnetostrictive materials, ultrasonic pulverizers, ultrasonic atomization, ultrasonic tooth cleaning, reversing radar, ultrasonic distance measurement, phacoemulsification, ultrasonic descaling, ultrasonic motors, and all other devices and equipment that use piezoelectric and ultrasonic.
Especially in the process of research and development and production of ultrasonic equipment, how to know whether the ultrasonic component products involved by the engineer meet the requirements, its quality, performance, and parameters, need to be tested by an ultrasonic impedance measuring instrument.
1. Transducer: No parasitic circle should appear in the admittance circle, the resonance impedance should be as close to the design impedance as possible, the dynamic impedance should be low, the quality factor Qm should be close to the design requirements, and the capacitance should match the circuit.
2. Piezoelectric ceramic sheet: The quality of the device can be judged directly from the admittance circle diagram and logarithmic coordinates. If there is delamination or cracks inside the ceramic sheet, the logarithmic curve will have multiple peaks, and the admittance circle chart will appear more A parasitic small circle.
3. Amplifier: From the design, processing and assembly, whether it is reasonable or defective can be directly seen on the guide circle diagram.
4. Production and processing of ultrasonic welding machine: use the results of the admittance circle to analyze the state of the welding machine, and find the problems of the welding machine through the analysis of parameters and graphics.
5. Production and processing of ultrasonic cleaners: The choice of vibrators requires that their vibration performance is as consistent as possible (bandwidth, quality factor, resonance impedance, dynamic impedance). On the admittance circle chart, there should be no parasitic circle as much as possible or no parasitic circle near the resonance point. It can analyze and measure the impedance characteristics of transducer manufacturing, incoming inspection, bonded transducer, and cleaning machine.
The whole machine measurement of the cleaning machine can calibrate the resonance impedance and static capacitance of the machine to match the power supply. It can analyze the characteristics of its new resonance point, impedance after water injection, capacitance and the vibration mode of the whole machine.
