The ultrasonic rail flaw detection system is used to detect internal rail flaws. The system is mounted on a telescopic axle and is suitable for speeds up to 60 km/h. The fourteen transducers that measure one rail are located in two wheel probes which are guided laterally centered above the web of the rail.
A separate workplace inside the track recording car is used to analyze the ultrasonic signals. The ultrasonic data are used to generate a side profile of the actual rail (consolidated B scan video image). A pattern recognition software is used to identify and classify the rail flaws. The Plasser measuring system supplies location and track information to the ultrasonic rail flaw detection system. Off-line multiple run comparison histograms can be created and analyzed.
