Impedance analysis of ultrasonic transducer and piezo ceramic 1khz-5mhz
Application fields: power ultrasonic equipment, piezoelectric ceramic production inspection, ultrasonic welding, ultrasonic cleaning, medical ultrasound, etc
Equipment name ultrasonic impedance analyzer measurable parameters remarks
The resonance frequency FS ultrasonic impedance analyzer of ultrasonic products is also called ultrasonic frequency measuring instrument, ultrasonic transducer parameter analyzer, ultrasonic transducer impedance tester, ultrasonic performance analyzer. The instrument is composed of hardware and software. The product can measure and evaluate the parameters, quality and comprehensive performance of various devices and equipment, such as ultrasonic tool head (ultrasonic mold), piezoelectric ceramic sheet, piezoelectric transducer, ultrasonic cleaning machine, ultrasonic welding machine, ultrasonic grinder, ultrasonic processing equipment, etc.
Especially in the process of research and development and production of ultrasonic equipment, how to know whether the ultrasonic parts and components involved by engineers meet the requirements, their quality, performance and parameters, we need to use ultrasonic frequency measuring instrument to detect. Transducer: the admittance circle chart shall not have parasitic circle, the resonance frequency shall be close to the design frequency as much as possible, the dynamic impedance shall be low, the quality factor QM shall be close to the design requirements, and the capacitance shall match the circuit. Piezoelectric ceramic chip: it can directly judge the quality of the device from the admittance circle diagram and the logarithmic coordinate. If there is delamination or crack in the ceramic chip, the logarithmic curve will have multiple peaks, and there will be multiple parasitic circles 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 state of the welding machine is analyzed by the results of admittance circle, and the existing problems of the welding machine are found through the analysis of parameters and figures. 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). In 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 the transducer and washer after the manufacture, incoming inspection, bonding. The measurement of the whole machine of the washing machine can calibrate the resonance frequency and static capacitance of the machine, so as to match the power supply, and analyze the characteristics of its new resonance point, impedance after water injection, capacitance and vibration mode of the whole machine.
