Made In China Ultrasonic Full Touch Screen Impedance Analyzer and Frequency Analyzer

Impedance analyzer

Application: all kinds of ultrasound parts testing: piezoelectric ceramic, transducer, ultrasonic cleaner,              ultrasonic plastic welding machine, water sound, magnetostrictive material, ultrasonic disintegrator,                ultrasonic atomizing, ultrasonic tooth cleaner, distance sensor,ultrasonic emulsification, ultrasonic descaling,        ultrasonic motor, and all other piezoelectric and ultrasonic equipment and device.     

In the ultrasound testing, the admittance circle diagram and logarithmic diagram are very important, because these  two diagrams is the main method to adjusting qualified. This instrument has below parameters:  resonance frequency (Fs),maximum conductance (Gmax),bandwidth(F2-F1),antiresonance frequency (Fp),        quality factor(Qm),Free capacitor (CT),dynamic resistance (R1),dynamic inductance (L1),dynamic            capacity (C1),direst capacitance (C0),effective electro-mechanical couple factor(Keff),planar            electromechanical coupling factor(Kp), free dielectric constant. 

The software specially designed for ultrasound applications makes it more convenient and simpler to use than imported instruments in the application. It does not require professional operations and can calculate more parameters.

Users can store and print any graphics, and can save the parameters as a computer Excel table, which greatly improves the convenience of users. Users can also customize the qualification conditions themselves, and the software can automatically determine the qualification.

The system provides a dozen parameters, the average user is commonly used the following parameters:

Fs: mechanical resonant frequency, that is the operating frequency of the vibration system, the design should be as close to the expected value, and must match the power supply point.

R1: dynamic resistance, the piezoelectric vibrator series branch resistor, the internal resistance of the device is, the greater the resistance, the higher the power loss of energy.

Qm: mechanical quality factor, Qm, the higher electro-acoustic transducer conversion efficiency, but also the more narrow bandwidth transducer, generally moderate better.

CT: freedom capacitors, piezoelectric device capacitance value at 1kHz frequency, this value is subtracted dynamic capacitance C1 can get real capacitance C0.

Fp: anti-resonance frequency, the piezoelectric oscillator resonant frequency of parallel branches.

Correct testing transducer mode as below:

Note transducer placed posture, usually lying down on the cushion, put the wrong posture can lead to
inaccurate measurements

This instrument can provide the following coordinate characteristic diagram.
