Digital signal processing

The NRS-260 rail flaw inspection vehicle features 32-channel digital signal processing, allowing real-time sequential data processing, improved signal-to-noise ratios, and higher testing speeds with fewer false positive test results. The System 48 (a 48-channel option for NRS-260) is available, which includes a sweeper wheel and tracer wheel enhancements.

Wheel probe technology

The NRS-260 uses Nordco's exclusive XL9-11 wheel probe technology designed specifically to perform ultrasound testing on rail, including eleven inspection transducers:

  • One zero-degree crystal for both web coverage and base detection
  • One 45-degree forward-facing crystal and one 45-degree rear-facing crystal for full rail web coverage
  • Three 70-degree forward-facing crystals (field, center, and gage) and three 70-degree rear-facing crystals, (field, center, and gage) for full head coverage
  • One side-looking field crystal and one side-looking gage crystal for longitudinal cross-rail coverage

Pattern recognition and defect analysis

The NRS-195 is fully automated and digital, incorporating the following key features:

  • Pattern recognition defect classification - incorporates artificial intelligence to recognize common rail conditions, as well as recognize and classify defects. It is an adaptive learning system that adds new defects to the library as they are analyzed, allowing the system to recognize new defects automatically.

  • On-board Run-on-Run - a comparative analytical tool that compares prior test results to current test results for the same portion of the rail. The system alerts the operator of a match to a prior indication and allows for real-time comparison and the opportunity to identify any changes in the rail's health.
