Hi Everybody,
I am working on a project that needs to drive 5 (175 watts) Piezoelectric Ultrasonic Transducers, the system needs to output clear ultrasonic sound at 40 kHz (precise sine wave)
The system needs to produce a very clear sound (of course not for the human ears) of 40 kHz sine wave
Currently, I have these transducers from Aliexpress https://www.aliexpress.com/item/32978115507.html?spm=a2g0s.9042311.0.0.49fc4c4dCArXYp
Product size and performance parameters:
Model: CH-S42-50x2.6
Resonant frequency (kHz): 40 ± 1
Static capacitance (pF): 8000 ± 10%
Resonance impedance (Ω): ≤20Ω
size: 50 * 2.6mm (diameter * height)
Power (W): 35w
Insulation resistance (2500V DC): ≥ 100MΩ
Does anyone have an idea of how we can drive these transducers from a simple 40KHz sine wave generator (1v p-p)
I thought to try to use a high power audio amplifier, for example of 300W output with a high bandwidth (< 60kHz) and connect the output to a high-frequency transformer to step up the voltage, so the question is, will this work?
Do you have any suggestions/advice about how to do it?
Can piezoelectric ceramic ultrasonic transducers as in the link above produce clear/clean sine wave sound?
Do you think anything else might be better (to produce good sound quality)?
Any help will be highly appreciated!
