Small EMAT sensor

Does anyone make small(5x5mm) shear wave EMAT with frequency up to 5MHz? We have RITEC RAM10000 for a pulser and BR640 for a receiver.

Hello Koichiro Kawashima,

Panametrics NDT, a business of R/D Tech Instruments Instruments, Inc. manufactures a magnetostrictive EMAT sensor that is approximately 2.25 MHz and 1/2" element diameter. This EMAT is designed for use with a conventional ultrasonic flaw detector, not a Lorentz Force EMAT pulser.

Keep in mind, the magnetostrictive principle that our E110-SB utilizes only works if the parts have a coating of high temperature oxide scale, which acts as the active element. The transducer will not work on clean metals. Please contact R/D Tech for additional information.

Regards,
Katie Lee
Product Manager, Transducers

Re: Small EMAT sensor
Sonatest can also supply similar a transducer (EMAT-0.5STD) with similar limitations. Side entry Cable, overall height around 25mm

Re: Small EMAT sensor
Call the people from IzfP... they have developed a nice system which we now evaluate ... looks promizing as it works nicely...
Even transducers show an interestng behaviour - but you need their electronics...
All other stuff we had seen before, did not cover our needs and looked vey experimental, this is now a nice approach to EMAT for mobile carry-on inspection....

Dear Koichiro Kawashima,
we manufacture an EMAT system suited to applications such as thickness measure, and residual stress evaluation.
EMAT probe for shear horizontal thickness 0° wave (3-4 MHz)has active area of 6x6 mm, external case about 30 mm diameter. A dual axis probe (two crossing linear polarization) is exploited for residual stress evaluation (see article on ndt.net - direct link below.
Additional info and documentation available: which is your target application?
Regards

massimo gori

Despite having managed to halve the weight of similar portable X-Ray generators available on the market (while continuing to provide the same power output), the SITEX CPSERIES generators feature a shutter, a laser pointer, a beryllium window, an aluminum filter and two integrated diaphragms (customized sizes are available upon request). Without compromising the robustness and reliability for which ICM products are renowned, the small size and light weight of the SITEX CPSERIES will radically change the way that you perform your RT inspections. And you will see a positive impact in terms of both quality and return on investment (ROI).
