Magnetic wheels for scanner

We are about to remodel our UT-scanners for use at ferritic surfaces. The wheels shall be driven by magnetic wheels (diameter ~45mm). The question is where to get these wheels. Someone who know about such offers please contact me.

Re: Magnetic wheels for scanner
Envision Product Design manufactures intelligent magnetic crawlers in several sizes and configurations for industrial NDT, as well as providing up-grades and refurbishing of simple UT crawlers. Dr. Joe Imlach, a magnetic specialist, designs our wheels and as a result we achieve much higher performance than by placing soft iron plates on the sides of toroidal magnets. We built custom magnetic wheels, with or without integrated bearings and gears, in a broad range of diameters (12mm to 100mm) with attachment strengths from 2 kg to over 200 kg per wheel. We would be happy to quote your wheels if you can provide the needed details.

do the wheels need to be magnetic?
wouldn't a magnetic plate suspended 0.5mm gap from test surhave

Joerg

THis is the trick.
You get 416ss alloy bar stock and Neodynium magnets.

The wider the face the better 7mm will do. Place the magnet between the bar stockthat you have cut down in to wheel hubs and place the magnet so that the N & S poles are faceing the wheel hubs you need about 10 to 15mm gap between the hubs to seperate the fields. depending on your load a 5cmx5cmx2.5cm magnet should do.

Joerg we make the best wheels in the biz if you need help shoot me a note. Mark

Product Spotlight

Varex Imaging Large Field of View (FOV) Digital Detector Arrays (DDAs)

A larger FOV DDA can reduce the space and volume of the X-ray inspection system on the factory floor
...
, enable faster scanning times, better throughput and better resolution images at a lower dose. 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.

NEW! The PragmaPro Instrument Platform

The PragmaPro is based on a modular cartridge technology and supports various NDT instrument modal
...
ities such as UT, PAUT, ECT and many more. This new platform is based on a machined, powder-coated aluminum frame for shock-proofness, best sealing qualities and maximum heat dissipation. This is practical to extend the outdoor temperature range and/or to extend the power injected in the transducers. The PragmaPro is aiming at a very wide range of applications, such as weld scanning, corrosion mapping and composite testing.
