Advanced, Portable Rail Flaw Detector
OnePass is a portable rail flaw detection system designed to inspect single tracks with only one pass over the rail. This innovative, portable solution for manual rail inspection is ideal for ultrasonic testing in railway yards, crossovers, plug rail and short run applications.
-
Nordco has bundled the latest detection and processing technologies in a compact rail test unit to bring leading UT capabilities to hand testing applications. OnePass is designed with the same RSU and Digital Signal Processing Technology as is employed in full featured rail inspection vehicles.
-
Ergonomically designed, the OnePass interrogates rail integrity with eleven transducers and represents software recognized defects in a B-Scan view. Defect verification is supported with an integrated hand test kit and on board flaw detection scope software.
XL9-11 Wheel Probe
The OnePass employs Nordco’s exclusive XL9-11 wheel probe technology designed specifically to perform ultrasound testing on rail, featuring eleven inspection transducers and a maintenance free direct encoder for local distance measurement:
-
One zero-degree crystal for both web coverage and base detection
-
One 37.5-degree forward-facing crystal and one 37.5-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
Record your test results
Test results are fully recordable, meaning you can store, evaluate, and compare results at a later time. Easily maneuverable due to its small size and weight, the system is ideal for plug rail testing as well as for yard tracks, frogs, and switches.
