OKOndt ET-73HS Eddy Current Rail Testing System

OKOndt ET-73HS Eddy Current Rail Testing System

Overview

The OKOndt OKOSCAN ET-73HS System is designed for automated high-speed eddy current testing of the working service of the rail head and of the rail edge. The OKOSCAN ET-HS System detects all types of critical defects: transverse fatigue cracks and headchecks, quench cracks and wheel slippage areas and  can ensure testing at speeds up to 40 km/hr. (25 miles/hr.) with test results saved on the database. Features 2 Eddycon D eddy-current flaw detectors, sixteen eddy-current (probes) (ECP) - eight for each rail, a track gauge and specialized software.

Flaw Detector Trolley

The trolley is a steel support structure with wheels, alignment system (pneumatics), lifting and lowering mechanism (electronic monorail hoist) and positioning system eddy current probes. The trolley provides accurate positioning and movement of the eddy current probes. Pneumatic equipment mounted to the trolley is used for automatic adjustment of the trolley to the track width and ensures positioning of each probe on its own testing area.

Key Features

  • Capability to test curves with a radius of less than 200m (660 ft.).
  • Automatic positioning and alignment of the track
  • Easy to maintain
  • Capability to control the suspension system

   

Eddy Current Probes

The OKOSCAN ET-73HS is equipped with 16 eddy current probes (ECP) - 8 for reach rail. 

Key Features & Specifications
  • The central operating frequency is 200 kHz
  • Orientation of the detected defects - transverse, at an angle relative to the rail axis
  • Fixing bogies made of wear-resistant material are used to unambiguously position the probes on various rail profiles
  • There needs to be clearance between the working surface of ECP and rail surface to prevent damage to the probes
  • All the ECPs are positioned on the rails so that 100% testing of the working edge and the running surface is ensured. 

Specialized Software

The OKOSCAN ET-73HS is supplied with pre-installed software that consists of:

  • Software for setting up the flaw detectors
  • Software for control and analysis of the current data
  • Software for viewing the testing results
