low frequency UT probe

Dear all,
Who can help or knows a possible source?

We are looking for a UT probe with almost linear efficiency (if excited by a continuous sine wave) in the band width from (roughly) 10kHz up to 200kHz (we want to sweep the frequency across this range).
Also probes from around 10-100kHz and from 50-200kHz might be of interest.
We need a flat coupling area to couple this probe to solids.

thanks and regards
Jens

Re: low frequency UT probe
Hi,
You can contact probe manufacturers such as Krautkramer with your specific requirement. They will construct and supply to you.

Re: low frequency UT probe
Hi,

Physical Acoustics Corporation's S9208 sensor is pretty good for this application. It has flat response in this frequency bandwidth. I have used it as an excitation sensor for years.
