Ultrasonic Rail Testing

The new UT-M18, an inspection system mounted on a self-propelled electric trolley, is the latest addition to ScanMaster's product line for ultrasonic rail testing of in-situ metro and underground railways. The innovative sled structure of the UT-M18 enables simultaneous ultrasonic inspection of both rails using multiple probes for maximal coverage of the rail profile. An advanced self-alignment module maintains sled positioning in all track scenarios, ensuring reliable automatic inspection.

The rail height monitoring mechanism automatically adjusts relevant ultrasonic settings when a change in rail type is detected. The system is capable of inspection at speeds of up to 20 km/h. Results are presented in real time in B-scan display.

The UT-M18 features 18 ultrasonic detection channels. The system’s unique capabilities include:

  • Innovative unique “wear free” probe housing design
  • Optional integrated GPS for defect localization
  • Easy mounting / demounting of the trolley from the rail in 20 minutes or less
  • Exclusive water flow mechanism designed to minimize water usage
  • Unlimited ability to cross above rail switches and intersections
  • Easy “zero cost” maintenance
  • Minimal power consumption allowing for extended overall system operation

The TrackMaster

The UT-M18 is delivered with integrated TrackMaster software, a complete package for data collection, presentation and analysis. The software covers all phases of system operation, from configuration and inspection to post-processing. Data can be processed in both offline and online modes. In addition, data records can be used to establish a baseline for comparative periodic monitoring of rail conditions.

The analysis function is used to identify and categorize flaws in a scan. It is based on a defect finder algorithm with an integrated noise reduction algorithm or/and an integrated AI/Fuzzy Logic algorithm. Using this analysis features eliminates the need for specially trained personnel and reduces the total cost of system usage.

The analysis module enables the issue of a report containing a list of all suspected flaws, their locations in the scanned track and the distance from the nearest reference points.
