Ultrasound NDT (non-destructive testing)

  1. Jan 5, 2015 #1
    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 dont 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 ?? :)

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

    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 gotta love the HP/Agilent gear, Mike :)

    I wasted way too much time. :headbang:
    I do indeed. :oldlove:
