Ultrasound NDT (non-destructive testing)

In summary, the OP is looking for a way to power and drive a UT without the use of a pulser-receiver. He has contacted a specialist from Olympus and been told that it is not possible. He is reverse engineering a commercial product.

Hi all,

I've a question and I hope that I can get some answers here.

As what my project has tasked, and what my lecturer had said. He needs me to build a device for NDT Testing.

Currently the set up is that I would source for a transducer via olympus coupled with a USB oscilloscope capable of generating an AWG wave.

So the set up would be Transducer > Amplifier <> USB Oscilloscope > Laptop

USB oscilloscope : http://www.tiepie.com/en/products/Oscilloscopes/Handyscope_HS5
Ultrasound Transducer : http://www.olympus-ims.com/en/ultrasonic-transducers/immersion/

I've gotten in touch with the specialist from Olympus and he told me it isn't going to work since the USB oscilloscope coupled with a high gain amplifier is capable of powering and driving the transducer. I've feed-backed to my lecturer and he told me that this certainly can be done without the pulser-receiver.

I can't really find any source of this type of project or set-up on the net and I really hope someone here can advise me and if possible, providing some sort of aid or help since I am pretty helpless now.

Reverse engineer a commercial product. UT is an industry standard.

Hi,

I don't see a commercial product that uses AWG and amplifier to drive a UT. Those in the market are using pulser-receiver.

Maybe the market is teaching.

Like reinventing the wheel, so far they've all been quite round. A three cornered wheel might not be a success.

What's an AWG wave?

Ah, I think you're right, Dave. I use Arbitrary Function Generators often, but was confused when the OP mixed the term in with "oscilloscope":

its not a term I have come across before
yeah maybe he meant USB oscillator ?? :)

This is the AFG that I use most of the time, the HP/Agilent 33120A:

Ah, huh! That does sound more likely, but I suppose you can use either in an ultrasonic imaging application. Thanks for the link. :-)

Maybe. Dang acronyms.

Don,
I saw and did consider that one and thought ... No he said generator and I was thinking waveguide as just a transmission medium for that generated signal
but looking at some of the links your link gave suggest its an all in one solution :)

Isnt it fun speculating when we don't get all the info up front ;)

Ya got to love the HP/Agilent gear, Mike :)

FAQ: Ultrasound NDT (non-destructive testing)

What is Ultrasound NDT (non-destructive testing)?

Ultrasound NDT is a method of testing materials and structures without causing any damage. It uses high-frequency sound waves to detect any defects or flaws in the material or structure being tested.

How does Ultrasound NDT work?

Ultrasound NDT works by sending high-frequency sound waves into the material or structure being tested. These sound waves are then reflected back to a receiver, which analyzes the waves to detect any changes or abnormalities. The results are then interpreted to determine the presence of defects or flaws.

What are the benefits of using Ultrasound NDT?

One of the main benefits of Ultrasound NDT is that it is a non-destructive testing method, meaning it does not cause any damage to the material or structure being tested. It is also a quick and efficient way to detect defects or flaws, allowing for timely repairs and maintenance. Additionally, it is a cost-effective method compared to other testing techniques.

What types of materials and structures can be tested using Ultrasound NDT?

Ultrasound NDT can be used to test a wide range of materials and structures, including metals, plastics, composites, ceramics, and concrete. It is commonly used in industries such as manufacturing, aerospace, automotive, and construction to test components, structures, and pipelines.

Are there any limitations to Ultrasound NDT?

While Ultrasound NDT is a highly effective testing method, it does have some limitations. For example, it may not be suitable for materials that are highly absorbent or have irregular surfaces. Additionally, it requires a skilled operator and proper calibration to ensure accurate results.
