TecScan Phased Array Axle Scanner

TecScan Phased Array Axle Scanner

Complete train axle inspection in just a single scan

Complete Train Axle Inspection in Just a Single Scan

Designed specifically for the inspection of train axles, the TecScan Phased Array Axle Scanner performs a full 360° rotation of the phased array probe around the axle axis. Making use of the multi-angle capabilities of the phased array technology, the scanner produces simultaneous pulse-echo inspections at all refraction angles, covering all areas of interest within the axle with a single scan. The inspection results are easy to understand, and are presented either in the form of sectorial scans showing all refraction angles, as B-Scans at some specific refraction angles or as C-Scans corresponding to specific areas of the axle.

Features:

  • Detection of fatigue cracks in critical areas of in-service train axles
  • Perform inspections from the axle ends without having to completely disassemble the axles
  • Equipped with a high resolution rotational encoder that allows to monitor the circumferential location of the probe
  • Performs pulse-on-position scanning using an ultrasonic flaw detection unit over the full 360° range
  • Spring-loaded probe holder help maintain a constant coupling between the ultrasonic probe and axle for repeatability
