Ultrasonic Impedance Analyzer are mainly applicable to all types of ultrasound devices for measuring impedance characteristics, 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 all use of ultrasound equipment.
Impedance Analyzer is characterized by: ease of use, indicators and graphics combination of parameters is accurate, low cost of production can be very strong guidance.
Of piezoelectric devices for the proper use of impedance measurement is a prerequisite for the device. For piezoelectric devices, through the impedance analyzer can be its main parameters, 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)
Imports Impedance Analyzer Agilent 4294 prices around 300,000 yuan, the high price limited its domestic industrial sector applications, only a few domestic enterprises and research institutes have the imported equipment.
Compared with the Agilent 4294A, we have a lot of advantages. In addition to the cost, there are specialized ultrasound design software to make it in the application of imported equipment than convenient, simple, no need for professionals to operate, more parameters can be calculated.
Many manufacturers use our products to replace the Agilent 4294A, including the Institute of Acoustics, Chinese Academy of Sciences, Qinghua University, Panyu Dewey, which is identical to the detection of targets, but also has low cost, simple, user-friendly features such as software.
