Ultrasonics

Sperry utilizes 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.

15 ultrasonic channels per rail deliver optimum detection across the entire rail head, web, and a portion of the base. Sperry's X-fire technology increases transverse defect detection by 30% in areas of less than perfect rail surface conditions.
