Product Description

MQ Instruments PV-80A

 

PV-80A Impedance analyzer—Detect all ultrasonic related parameters, application for underwater acoustic area and High Power ultrasonic area such as  piezoceramic, piezoelectric crystal, ultrasonic transducer, converter, ultrasonic welding, ultrasonic sensor and so on.

 

 

 

 

 

 

 

 

 

 

Operation window:

 

 

 

 

 

Users can judge the elements from the impedance diagram directly.

2) Parameters:

Fs: mechanical resonance frequency: The working frequency of ultrasonic system, it should reach the expectation value as much as possible in the design; also, it should be matched with the ultrasonic power.

 

C0: The capacitance of static branch in the equivalent circuit of piezoelectric elements. Balancing the C0 properly can increase the factor of ultrasonic power.

 

Qm: Mechanical quality factor. When Qm is higher, the efficiency of system is higher. Yet, if Qm value is too high to be matched with the ultrasonic power, the system cannot run efficiently. Qm needs to be set within the proper range. Generally, Qm of ultrasonic cleaning transducer is between 500 and 1000. For ultrasonic welding system, Qm is between1500 and 2500.

 

   R1: the dynamic resistance, it should be as lower as possible in the same condition.

Basic principle:

 

      

 

 

Half-power point, F1, F2. From diagram we can find, there have two frequency in F2>Fs>F2,Gmax/2=(F1,F2) 

 

4)Fp:FP is the max impedance for piezoceramic transducer. 

5)Qm: Qm=,or  Qm=

 

6 CT:CT reflect the activity capacity for  the pizoceramic under 1KHZ.

7)R1: R1=1/Gmax, Gmax is the max admittance.

8)    L1 :

L1=

 

9)C1:

C1=

10)C0: C0=CT-C1,

 

11)Keff:

Keff=

12)Kp:

This factor only used in piezoceramic .

The difference between our Impedance Analyzer with the Agilent Impedance Analyzer:

Our Impedance Analyzer can completely replace  Agilent 4294, it also has advantages, such as: low cost, easy operation, friendly software interface. 

 

 

PC requirements

 

Operation systems: Microsoft Windows 2000, XP

Nearly have no request for your computer in RAM, hard disk space. Use USB port, graphics card with 800*600 or above.

 

 

 

 

There are no special skills required by workers. The measuring result can be obtained by just pushing one key.
