SIUI RailTek Digital Rail Flaw Detector

SIUI RailTek Digital Rail Flaw Detector

For Rail Weld Joint Inspection

Portable, Easy-to-Use, Reliable

The RailTek ultrasonic flaw detector for rail weld joints is a digital portable rail testing machine with powerful functions and easy operation, making it the first choice for rail weld joint inspection. The RailTek is used for inspecting welds and flaws in the rail head, rail waist and rail bottom with both single probe reflection method and tandem dual angle probe inspection method.

  • Compact & Portable: The whole unit weighs (battery included) is approx. 2.5 pounds (1.2 kg), making it suitable for field work.
  • B-Scan Mark Function: Automatically mark alarm signals on the rail weld joint cross section on a B-Scan image.
  • Easy Operation: There are just a few concisely-defined keys, easy to operate with only one hand.
  • Low Power Consumption: The Li-polymer battery can support up to 6 hrs. of continuous operation.
  • Strong Performance: High defect inspection rate can satisfy precise rail joint inspection.
  • Dynamic Recording: Real-time Cineloop.

 

 

 

 

Features

  • Max. sampling rate 240MHz; Measurement resolution 0.1 mm.
  • User friendly report with quick label for defect properties, position and testing processes, enabling easy post analysis and determination.
  • 20 - 500Hz PRF with 10 steps adjustable: avoids reverberation signals during flaw detection.
  • B-scan images can be acquired by scheduled scanning.
  • Measures crack height by edge peak echo method and image freeze function.
  • The DAC curve works with the echo compare function, making echo quantification of different distances and amplitudes more convenient.
  • 5.7" high brightness TFT LCD.
  • Different color schemes can meet the requirements of different application environments and habits.
  • EN-12668-1 compliant.

Application Examples

 Single 70° Angle Probe

  • Use primary wave to scan rail tread and rail side for making DAC curve on No.1-5 SDH in B area of GHT-5 calibration block with single 70° angle probe.
  • Rail head inspection.

Single 45° Angle Probe

  • Use primary wave to scan forward and reverse from rail tread to rail waist with single 45° angle probe.
  • Rail inspection from rail head to rail foot.

Tandem Dual-Element Angle Probe

  • Use a pair of tandem placed 38° angle probes with a crawler to scan the rail waist.
  • Echoes from the flat bottom holes in GHT-1a calibration block.

Dual 45° Angle Probe

      • Use a pair of 45° angle probes to scan each side of the rail foot and rail head.
      • An echo from No. 5 FBH in GHT-1a calibration block.
