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 RPS520A (by engineers or ordinary production workers).

RPS520A is based on the RPS70A and RPS80A, a new generation of ultrasonic components analyzer.

Piezoelectric ceramics, transducers, ultrasonic cleaning machines, ultrasonic plastic welding machine, underwater acoustic, magnetostrictive materials, ultrasonic grinder, ultrasonic atomization , reversing radar, ultrasonic ranging, phacoemulsification , ultrasonic motors, and all other devices used in piezoelectric and ultrasound.
