RTS18-B portable dual rail ultrasonic flaw detector can detect various defects and cracks on the rail head, waist and rail bottom during the travelling of the flaw detection trolley. The system has two modes: A-scan and B-scan. B-scan is the scanning mode used in actual detection driven by the encoder to continuously collect and record corresponding information. The encoder generates a pulse every 3mm, and the flaw detection trolley collects the probe signals on the left and right rails in real-time according to the pulse signal.

The probe adopts a wheel design, each probe is equipped with 9 channels, and each rail uses one probe for acquisition. There are 18 channels in total for the dual rail, which ensures that the flaw detection system can comprehensively and reliably detect the rail and avoid the loss of the probe caused by high-speed movement.
