Brandson replacement ultrasonic transducer good quality low cost

The ultrasonic transducer utilizes its piezoelectric ceramic's resonance at ultrasonic frequency and converts electrical signals into mechanical vibrations by the inverse piezoelectric effect. It is a very essential part of the whole ultrasonic system. There are many factors that affect the final quality of the ultrasonic converter's performance. Among those factors, there are:

Free capacitance CT: the capacitance value of the piezoelectric device at 1kHz, this value is consistent with the value measured by the digital bridge.

Dynamic resistance R1: the resistance of the serial branch of a piezoelectric transducer, R1=1/Gmax, Gmax is the maximum admittance.

Dynamic inductance L1: the inductance of the serial branch of a piezoelectric transducer, the formula: L1=R1/ 2π (F2-F1), R1 is dynamic resistance, F1 and F2 are the half-power points.

Dynamic capacitance C1: the capacitance of the serial branch of a piezoelectric transducer.

Static capacitance C0: C0=CT-C1, CT is free capacitance, C1 is the dynamic capacitance (Note: Static capacitance can also be calculated from the offset distance between the center of the admittance circle and the conductivity axis (G-axis), however, in real practice, the formula: C0=CT-C1 is often used. So, we use this formula here for the calculation of static capacitance.)

Effective electromechanical coupling coefficient Keff: Keff is defined as the square root of the ratio between the stored mechanical energy to the total stored energy, while the empty-loaded piezoelectric transducer is in its mechanical resonance.

Planar electromechanical coupling coefficient Kp: this parameter is only used in piezoelectric ceramics; it reflects the parameters of the electromechanical coupling effect when the thin round plate is polarized and electrically excited along its thickness direction and doing the radial stretching vibration. The formula could be chosen in the software.
