Impedance Analyzer are mainly applied to measure impedance characteristics of all types of ultrasound devices, including: piezoelectric ceramics, transducers, ultrasonic cleaning machines, ultrasonic plastic welding machine, water sound, magnetostrictive materials, ultrasonic grinder , ultrasonic spray, ultrasonic scaler, reversing radar, ultrasonic ranging, phacoemulsification, ultrasonic cleaning, ultrasonic motors and so on. Impedance Analyzer is characterized by: easy of use, combine indicators with graphics,

accurate parameters , low cost, strong guidance for the production.

 

Impedance measurement of piezoelectric devices is a prerequisite for the proper use of the device. For piezoelectric devices, its main parameters can be achieved through the impedance analyzer, including: the resonant frequency Fs, the anti-resonant frequency Fp, half-power point of F1 and F2, the largest admittance Gmax, electrostatic capacity C0, dynamic reactor R1, dynamic capacitance C1, Dynamic inductor L1, free capacitor CT, the free dielectric constant, mechanical quality factor Qm, electromechanical coupling coefficient Keff , Kp, K31, K33, and piezoelectric devices can draw five characteristic curve (Nath of maps I, impedance characteristics map , polar coordinates map admittance, Impedance polar diagram, Logarithmic plot).

 

The high price of imports impedance analyzer Agilent 4294 is around 300,000 yuan, which limited the machine's domestic industrial applying sector ,thus only a few domestic enterprises and research institutes own the import equipment.

 

Compared with the Agilent 4294A, we have a lot of advantages. In addition to the low cost, we are specialized in ultrasound design software to make it more convenient ,simple than import equipment in application. Also it does not need professionals to operate, and more parameters can be calculated.

 

Many manufacturers , including the Institute of Acoustics, Chinese Academy of Sciences, Qinghua University, Panyu Dewey replace the Agilent 4294A with our products, whose detecting index is identical to the detection of targets. And our products is characterized by : low cost, easy to operate, friendly software interface .
