ultrasonic impedance analysis of ultrasonic transducer 1khz-1mhz
Impedance analyzer can measure and evaluate to match circuit
For piezoelectric ceramic chip, we can directly judge the quality of the device from the admittance circle diagram and logarithmic coordinates. If there is delamination or crack in the ceramic chip, the logarithmic curve will appear many peaks, and there are many 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 diagram
For 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
For the 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, As far as possible, there is no parasitic circle or there is no parasitic circle near the resonance point. It is possible to analyze and measure the impedance characteristics of the transducer and washer after the manufacture, incoming material inspection, bonding. For the measurement of the whole washer, it is possible to calibrate the resonance frequency and static capacitance of the machine, so as 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
