Ultrasonics

We utilize Roller Search Units (RSUs) to apply ultrasonics to the rail. RSUs adapt to less than perfect rail conditions thereby ensuring uniform and constant contact with the rail surface, resulting in higher defect- detection ratios.

In 2007, we introduced the X-Fire RSU to identify defects otherwise hidden by surface conditions. X-Fire complements our standard detection techniques and represents the most advanced method of ultrasonic detection by utilizing proprietary technology and positioning of probes.

   X-Fire RSU

• Obliquely angled probes that are used to identify difficult to find defects such as: reverse detail fracture, transverse defects in the gauge corner.
• Ability to detect defects in spite of certain surface conditions such as: head checking, shells and worn rail profile.

  UX-6 RSU

• Six discrete transducers (37, 3-70’s, Sidelooker, and 0)
• 70’s used to find TD’s and head defects
• 37’s used to find bolt hole cracks and web defects
• Sidelooker used to find shear breaks and vertical defects
• 0 used to find bolt hole defects, base defects as well as corroborate other transducer data (LER)
• Two UX-6’s per rail provide complete coverage of testable rail

   UX-9 RSU

• Nine discrete transducers (2-37’s, 6-70’s, 0) all in one RSU
• In combination with one VSH provides complete coverage of testable rail

   VSH RSU

• Sidelooking transducers (both field and gage)
• In combination with one UX-9 provides complete coverage of testable rail

   High Speed RSU’s

• 6.5” and 9” versions used at speeds above 25 mph (40 kph) and up to 62 mph (100 kph)
