WideFrequencyRange 1KHZ-1MHZ Ultrasonic Analyzer For Transducer Resonance Frequency With Admittance And Logarithmic Diagram

The Ultrasonic Impedance Analyzer can measure and evaluate the parameters and performance of various devices and equipment,  such as piezoelectric ceramics, piezoelectric transducers, ultrasonic cleaners, ultrasonic welding machines, ultrasonic grinders, and ultrasonic processing equipment, etc.

The characteristics of the Ultrasonic Impedance Analyzer are: easy to use, combination of indicators and graphics, accurate parameters, low price, and strong guidance for production.

Characteristic Analyzer Features:

1. High precision of impedance measurement, accurate to 0.1Hz;

2. It is easy to judge defects through admittance circles and logarithmic curves;

3. The detection result completely distinguishes between the resonance point and the half power point;

4. The test data can be uploaded to the computer for unlimited storage and printing, and the data source can be traced;

5. Automatic filtering and statistics, parameter filtering can be set;

6. Automated operation has high efficiency, simple operation, and no human error.

Impedance tester application:

Transducer: The admittance circle diagram should not appear parasitic circles, the resonance frequency should be as close to the design frequency as possible, the dynamic impedance should be low, the quality factor Qm should be close to the design requirements, and the capacitance should match the circuit.

Piezoelectric ceramics: You can directly judge the quality of the device from the admittance circle diagram and logarithmic coordinates. If there are delaminations or cracks in the ceramic plate, the logarithmic curve will appear multi-peak, and the admittance circle diagram will appear multiple Madoka.

Whether the design, processing and assembly of the horn is reasonable or defective can be clearly seen directly on the guide circle chart.

In the production and processing of ultrasonic welding machine, the state of the welding machine is analyzed by the result of the admittance circle, and the problems existing in the welding machine are found through the analysis of parameters and graphics.

Production and processing of ultrasonic cleaning machine: The selection of the vibrator requires its vibration performance to be as consistent as possible (bandwidth, figure of merit, resonance frequency, dynamic impedance). On the admittance circle chart, there should be no parasitic circles as much as possible or near the resonance point. Impedance characteristic analysis and measurement of transducer manufacturing, incoming inspection, bonded transducer, and washing machine can be performed.

The whole machine measurement of the washing machine can calibrate the resonance frequency and static capacitance of the machine in order to match the power supply, and it can analyze its new resonance point, impedance after water injection, capacitance and characteristics of the vibration mode of the whole machine.
