Abstract
A system and method for inspecting a rail is provided. The system includes an ultrasonic transducer positioned to emit an ultrasonic beam onto the rail and receive a refraction beam, the ultrasonic transducer being movable between a first position and a second position. A sensor is operable to measure an angle of a carriage, the carriage being positioned on the rail. A controller is operably coupled to the sensor, the controller having a processor that is responsive to executable computer instructions when executed on the processor to cause the ultrasonic transducer to move to receive refraction beam in response to the measured angle indicating a rail radius of less than a predetermined first threshold.
