My question is this: 1) Can I use Teflon for my shoe, which has a sound velocity of 1.35km/s (cl) and 0km/s(ct). (so in theory should be OK) 2) Are there other materials that would be better suited for this heavy beam bending?... (even slower than Telfon) 3) Since it has a 0km/s transverse velocity, would it not be better than materials that do have a bulk modulus? 4) Are there any suggestions on how I can bend my beam such that I can get into the limited space, and what are your experiences concerning these applications. (I cannot get smaller probes, so changing the shoe is my only alternative, the probe is a Phased array probe).

Customers can also save time and money. With these benefits in mind, Varex Imaging has designed a family of large FOV detectors (4343HE, XRD 1611, 4343DX-I, 4343CT) for our industrial imaging customers. > Lyft™: Pulsed Eddy Current Reinvented StandEddyfi PEC Reinvented—CUI Programs Redefined Corrosion under insulation (CUI) is possibly the greatest u ... nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs.
