Up 60W 40KHz Ultrasonic Piezoelectric Transducer


Can we use arduino to control with pwm + mosfet to make the device in the picture work?

Have you got a datasheet for it to share?

I don't have a data sheet. There are only specifications from online stores on the internet. I know that if using AC power, it can be controlled through a ready-made module that I saw on YouTube.

How much power is needed to make the device "work"?

The Arduino can generate a signal for input to the amplifier that is required to drive the ultrasonic transducer. A MOSFET with DC power supply will not work.

Seems to be a transducer for an ultrasonic cleaning tank.
They are about 25 Ohm at resonance when properly mechanically loaded.
Which calculates to about 40volt AC, 1.6A (60V peak).
A H-bridge running on 30volt could work.

It may be more cost effective to use one of those modules than an Arduino plus H-bridge plus power supply.

The module may have a sinusoidal output, which the Arduino solution would not give.

Here is a 220V 40kHz 150W driver circuit board with 3 transducers.

Waiting to see how much ultrasonic power the OP need for the project.

No.

Hi, @achirathorn
Welcome to the forum.

What do you want to use the ultra-sonic transducer for?

Tom.... :smiley: :+1: :coffee: :australia:

you might need ear protection...
also for anyone else around...

Looks like the sort of thing that gets bonded onto the bottom of an ultrasonic tank.

Very useful too.

Degassing liquids, parts cleaning. I had access to a large tank. Been known to wash some clothes in it.

I have the exact same question. I want to build an ultrasonic cleaner from scratch. The country I live have no industries selling ultrasonic modules or transducers so I'm importing them, but the modules are expensive so I want to use arduino. I have this datasheet of the transducer. Is it possible to make it work with the arduino? 40khz and 60w


Yes, with a suitable driver. Study the thread.

I can’t see a role for Arduino here except for turning it on and off via a suitable driver .

Can’t see what you would do with a pwm output , these thing work at resonant frequency

Hi, @viini91
Welcome to the forum.

This might be what you need.

It is the basic driver, but you can download the instructions and it gives ideas on the physical construction of the bath.

It could generate the driving frequency, as input to an H-bridge driver.

Would that work tho , driving away from its resonant frequency ?

The Arduino would drive the H-bridge at the transducer's resonant frequency.

I believe some people here are not tuned into the concept of resonant frequency.

it is a transducer. a speaker that requires an ultrasonic signal to drive it. a 40 khz signal generator driving an amplifier that can provide 100 watts at 40 khz. audio gear typically filters that out. I would be on eBay looking for an industrial laboratory grade amplifier.
