OKO ETS2-77 Eddy Current Single-Rail Flaw Detector

Overview

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.

The ETS2-77 flaw detector can be folded for transportation or assembled

Specialized Software

The specialized software contains four main parts:

1. Eddy Current Channel Setup
   • Quick set up of all EC channel parameters – EC probe frequency, drive voltage, gain, filters, threshold level, sync type, etc. Four independent threshold levels for automated defect triggering (ALARM) for each displayed area. Test setups can be saved to the PC or tablet’s memory.
2. Testing
   • Real-time display of the 8 EC probe's information. Test results can be recorded on the PC or tablet memory. The signal visualization area display of different types of information. Re-calculation of the obtained defectograms can be performed.
3. Generating Railroad Names
   • Consists of the following components: Railroads, Divisions, Sectors, and Stages.
4. Review Test Results
   • Test results from the database can be read, archived, and printed out. Test results can also be reviewed from a remote PC, etc.
