ETS2-77 Eddy Current Single Rail 8-Channel Flaw Detector for Track Inspection

REQUEST A QUOTE

The ETS2-77 is intended for the mechanized inspection of rails and switches as well as confirmation of the results of a grinding application. The device is capable of testing a wide range of rail profiles.

 

Application

  • possibility to control the rail track and the track switch;
  • selective control of the separate rail track areas;
  • post grinding machines control;
  • all main rail profiles control Р50, Р60, 49E1, UIC 60 and others.
 
 
The operator is transporting the eddy current single rail flaw detector ETS2-77
  • Lightweight and compact

Weight of the assembled flaw detector does not exceed 23 kg (50 lbs).

Overall dimensions of the assembled flaw detector are not more than:

  • width - 900 mm
  • length - 1730 mm
  • height - 350 mm

The ETS2-77 flaw detector is a folding structure, which can be transported as it is a assembled in stowed position.

  • ETS2-77 intended use

The ETS2-77 is intended for the mechanized inspection of rails and switches as well as confirmation of the results of a grinding application. The device is capable of testing a wide range of rail profiles.

The eddy current technology enables localizing the following surface defects:

  • progressive transverse cracking (International Defect Code (UIC) 211);
  • fissuring /scaling at the gauge corner (International Defect Code (UIC) 2223);
  • shelling of the gauge corner (International Defect Code (UIC) 2222);
  • wheel burn (International Defect Code (UIC) 225).

The eddy current rail inspection equipment ETS2-77 is capable of evaluating the vertical depth of the defect, thus allowing a more efficient management of rail defects. The inspector can easily decide on the defect removal method: grinding, milling or re-railing, which saves time and money.

  • ETS2-77 flaw detector advantages

  • light aluminum frame;
  • specialized abrasion-resistant ECPs allow to evaluate the oblique cracks with up to 3 mm vertical damage depth;
  • 8 ECPs application allows to perform the control of the whole head rail surface in one run;
  • individual spring-mounted fitting of each ECP;

Eddy current single-rail 8-channel flaw detector ETS2-77 results

  • fast removal of the scanner during the transfer from one area to another;
  • individual adjustment of ECP position;
  • operating time – not less than 8 hours;
  • specialized SW for setting up, testing and inspection results review
