What is the function of an ultrasonic impedance analyzer?

Ultrasonic impedance analyzer can make accurate measurements in impedance range and wide frequency range. It uses the different conductive effects of objects. When a fixed low-level current is added to the surface of the object, the various device and equipment parameters and performance of the object are calculated through impedance. Impedance analyzer can measure and evaluate the matching with the circuit.

For piezoelectric ceramics, the quality of the device can be directly judged from the admittance circle diagram and logarithmic coordinates. If there is stratification or cracks inside the ceramic, the logarithmic curve will have multiple peaks and multiple parasitic small circles will appear on the admittance circle diagram.

For the design, processing and assembly of the amplitude transformer, whether it is reasonable or defective can be clearly seen directly on the admittance circle diagram.

For the production and processing of ultrasonic welding machines, the results of the admittance circle are used to analyze the status of the welding machine, and the problems of the welding machine are found through the analysis of parameters and graphics.

For the production and processing of ultrasonic cleaning machines: the selection of vibrators requires that their vibration performance is as consistent as possible (bandwidth, quality factor, resonant frequency, dynamic impedance Impedance). On the admittance circle diagram, there should be no parasitic circles or no parasitic circles near the resonance point as much as possible. The impedance characteristics of the transducer manufacturing, incoming material inspection, bonded transducer, and cleaning machine can be analyzed and measured. The whole machine measurement of the cleaning machine can calibrate the resonant frequency and static capacitance of the machine in order to match the power supply, and can analyze its new resonance point, impedance after water injection, capacitance and vibration mode characteristics of the whole machine.

The impedance analyzer is mainly applicable to the measurement of impedance characteristics of various ultrasonic devices, including: piezoelectric ceramics, transducers, ultrasonic cleaning machines, ultrasonic plastic welding machines, hydroacoustics, magnetostrictive materials, ultrasonic crushers, ultrasonic atomization, ultrasonic cleaning, ultrasonic ranging, ultrasonic emulsification, ultrasonic descaling, ultrasonic motors, etc. All equipment using ultrasound.

The characteristics of ultrasonic impedance analyzer are: easy to use, combination of indicators and graphics, accurate parameters, low price, and strong guidance for production.
