OKO ETS2-73 Eddy Current Double Rail Flaw Detector

OKO ETS2-73 Eddy Current Double Rail Flaw Detector


The ETS2-73 is a 16-channel double rail eddy current flaw detector. Conforms to EN 16729-2 to non-destructively test both the rail track and rail switches. Capable of selectively testing particular sections of the rail track, evaluating for surface defects after grinding machines, and can test all major rail profiles (49E1(S49), 54E1(UIC54), 60E1 (UIC 60), etc.). Application of this flaw detector ensures timely inspection of the rail head for presence of such defects as quenching cracks on the gauge corner of the rail head.




  • The equipment of the ETS2-73 flaw detector corresponds to ISO 15548-1 and ISO 15548-2 requirements
  • Folding aluminum frame
  • Simultaneous testing of left and right rails
  • Flaw detector’s structure allows to follow the current gage of the track and adjust to it
  • Specialized ECPs with protective wear-resistant covers allow to evaluate the depth of the rail vertical damage of up to 3 mm and do not care about the ECP integrity
  • Use of 8 ECPs allow to perform testing of the whole rail head per one ride
  • Possibility of crossing the rail bolt joints with up to 15 mm distance between the rails
  • Individual spring-mounted suspension of each ECP
  • Operation time from the rechargeable battery — minimum 8 hours
  • Specialized software to perform setting, testing and view the test results.
  • Uses Eddycon D Flaw Detector:
