Product description:
Ultrasonic impedance analyzers, especially in the process of ultrasonic equipment development and production, need to use ultrasonic impedance measuring instruments to know whether the involved ultrasonic components meet the requirements, their quality, performance, and parameters.
The impedance analyzer is mainly suitable for the measurement of impedance characteristics of various ultrasonic devices, including: piezoelectric ceramics, transducers, ultrasonic cleaning machines, ultrasonic plastic welding machines, underwater acoustics, magnetostrictive materials, and ultrasonic pulverizers.
Impedance analyzers can measure and evaluate to match the circuit
For piezoelectric ceramic sheets, the quality of the device can be judged directly from the admittance circle and logarithmic coordinates. If delamination or cracks appear inside the ceramic sheet, the logarithmic curve will appear multi-peak, and multiple peaks will appear on the admittance circle. parasitic circle
For the design, processing and assembly of the horn, whether it is reasonable or defective can be clearly seen directly on the guide circle diagram.
For the production and processing of the ultrasonic welding machine, use the result of the admittance circle to analyze the state of the welding machine, and find the problems existing in the welding machine through the analysis of parameters and graphics
The selection of the vibrator for the production and processing of ultrasonic cleaning machines requires that its vibration performance be as consistent as possible (bandwidth, quality factor, resonant frequency, dynamic impedance), and on the admittance circle diagram, there should be no parasitic circles as much as possible or no near the resonance point. The parasitic circle can analyze and measure the impedance characteristics of the converter manufacturing, incoming material inspection, bonded converter and cleaning machine, and the whole machine measurement of the cleaning machine can calibrate the machine's resonant frequency and electrostatic capacitance in order to match the power supply, It can analyze its new resonance point, impedance after water injection, capacitance and the characteristics of the vibration mode of the whole machine.
