Dear UT Expert,

How many of you believe that equipment and probes from same manufacturer will give better performance compare to mixing of probe brand with diffrent equipment brand? Share your experinece and knowledge.Thanks in advance.

Peter,
I have worked with many probes (old and new) from various manufactures. I have also used various test instruments. I have never, with the execption of phased array units, found that a family concept needs to be applied with regards to UT Probes. What one needs to look at is the performance characteristics of the probes themselves and the application they are to be applied to to make the determination as to which probe will work best for the job at hand. For general (quick) scanning, on large grained structures or rough surface finishes, I have found the Olympus product line excellent but I have found, in certain instances where the GE "Gamma" Series probes give a much better performance. I guess the bottom line is that you have to trial your system and applications with various probes from different manufacturers and find the one that works best for the given situation. Phased Array probes are a little different in that most Instruments are equiped with Probe recognition software but it generally only recognizes probes from the instrument manufacturer. This is not to say that you can not use a GE Probe on a system such as the OMNISCAN MX from Olympus. It just requires that you manually install the probe atributes into the system before you can begin your calibrations, which depending on the software model and system can be and often is a lengthy process rather then having the Array Probe and wedges already built into the instrument.
Hope this helps. Cheers...

All manufacture’s sales department will always tell you, to use only their own products only (I wonder why) but it is the hand behind the probe that makes the biggest difference.
All the best

I entirely agree with you. Particularly "the hand behind the probe" part.

Best wishes

Dear All,
It is heard that Olympus now are able to offer their phased array probes with connectors compatible with the GEIT Phasor instrument.
For UT application my opinion is that the head above and the hand behind the probe make the biggest difference.
