Ultrasonic Impedance Analyzer Test Instruments For ultrasonic Converter Frequency

Application fields of ultrasonic impedance analyzer

This instrument is applicable to all kinds of ultrasonic device measurement, including: ultrasonic transducer, ultrasonic horn, ultrasonic mold (tool head), piezoelectric ceramic, transducer, ultrasonic cleaning machine, ultrasonic plastic welding machine, underwater acoustic, magnetostrictive material, ultrasonic pulverizer, ultrasonic atomization, ultrasonic tooth cleaning, reversing radar, ultrasonic ranging, ultrasonic emulsification, ultrasonic descaling, ultrasonic motor And everything else that uses piezoelectricity and ultrasound. 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 frequency measuring instrument to detect. Transducer: parasitic circle should not appear in admittance circle diagram, resonance frequency should be close to design frequency as far as possible, dynamic impedance should be low, quality factor QM should be close to design requirements, capacitance should be matched with circuit. Piezoelectric ceramic chip: the advantages and disadvantages of the device can be judged directly from the admittance circle diagram and logarithmic coordinates. If there are delamination or cracks in the ceramic chip, the logarithmic curve will appear multiple peaks, and multiple parasitic circles will appear on the admittance circle 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 frequency, 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 frequency and static capacitance of the cleaning machine can be calibrated to match the power supply. The new resonance point, impedance after water injection, capacitance and vibration mode characteristics of the whole machine can be analyzed.
