Ultrasonic impedance analyzer is applicable to all kinds of ultrasonic device measurement, including: ultrasonic transducer, ultrasonic horn, ultrasonic mold (tool head), independent piezoelectric ceramics, transducer, ultrasonic cleaning machine, ultrasonic plastic welding machine, underwater acoustic, magnetostrictive materials, ultrasonic pulverizer, ultrasonic atomization, ultrasonic tooth cleaning, reversing radar, ultrasonic ranging, ultrasonic emulsification, ultrasound Descaling, ultrasonic motors, and everything else that uses piezoelectric and ultrasonic devices and devices.
Especially in the process of ultrasonic equipment development and production, how to know whether the ultrasonic parts and components involved by the engineer meet the requirements, their quality, performance and parameters, it is necessary to use ultrasonic impedance meter to detect.
Transducer: parasitic circle should not appear in admittance circle diagram, resonance impedance should be close to design impedance as much as possible, dynamic impedance should be low, quality factor QM should be close to design requirements, capacitance should be matched with circuit. In addition, if there are multiple parasitic peaks on the ceramic chip, we can judge whether it is good or bad from the logarithm admittance diagram. Whether the design, processing and assembly of the horn are reasonable or defective can be seen directly on the guide circle diagram.
In the production and processing of ultrasonic welding machine, the status of the welding machine is analyzed by using the results of admittance circle. Through the analysis of parameters and graphics, the existing problems of the welding machine are found.
Production and processing of ultrasonic cleaning machine: the selection of vibrator requires its vibration performance to be as consistent as possible (bandwidth, quality factor, resonance impedance, dynamic impedance). On the admittance circle diagram, there is no parasitic circle as far as possible or there is no parasitic circle near the resonance point. It can be used to analyze and measure the impedance characteristics of transducer manufacturing, incoming material inspection, bonded transducer and cleaning machine.
The resonance impedance and static capacitance of the cleaning machine can be calibrated to match the power supply. The new resonance point, impedance and capacitance after water injection and the vibration mode characteristics of the whole machine can be analyzed.
