Portable Ultrasonic Impedance Measuring Analysis
For ultrasonic components measuring instrument, the most important is the admittance chart, logarithmic graph of the two graphics (the two graphics is the main method of qualified qualified), and more than a dozen parameters: resonance frequency Fs, the maximum conductance Gmax, bandwidth F2-F1, anti-resonance frequency Fp, quality factor Qm, free capacitance CT, dynamic resistance R1, dynamic inductance L1, dynamic capacitance C1, static capacitance C0, effective electromechanical coupling coefficient Keff.
The Measuring instrument which can easily replace much more complex and more complicated, also many times more expensive instruments from Agilent/HP, as for instance: HP Impedance Gain-Phase Analyzer 4294A, Agilent E5100A, Network Analyzer, HP 3563A, Control System Analyzer etc. It is also very easy to use HS520A (by engineers or ordinary production workers).
HS520A is based on the HS70A and HS80A, a new generation of ultrasonic components analyzer.
Our products have four major advantages
Test equipment is the most important part of product quality checks, so the product of “credibility” is essential. Our products have four major advantages:
1. Tsinghua University and the Chinese Academy of Sciences Institute of Acoustics jointly developed technology.
2. Since 2001, our HS60A/70A series of products to the market has been 15 years , thousands of customers use in the industry, has become a matter of fact the ultrasound industry measurement standard.
3.Over the past 15 years, more than 200 colleges and universities have been using our instruments, because they often have more than 20,000 imported Agilent instruments, 4294A. Our instruments have been tested many times with imported Agilent instruments. It turns out that the results of our instruments are completely trustworthy.
4. Our instruments have been used by many German and US ultrasonic testing companies as test instruments. The instrument is the key to quality control.
