ETher RailCheck Eddy Current Flaw Detector

ETher RailCheck Eddy Current Flaw Detector


The ETher RailCheck Eddy Current Flaw detector is designed to easily detect and record surface breaking cracks in the head of rails. It combines a hand-held Eddy current flaw detector with a custom probe designed to inspect the running surface of the rail. A special trolley allows the operator to walk the probe down the rail with minimal effort. The specially designed probe allows the field and gauge corners to be inspected together with the rail face. The Eddy current flaw detector can trigger an audible and visual alarm should a defect be detected. The instruments' display shows the presence of potential defects in the rail and the complete inspection is continuously recorded for later analysis.



  • Single Rail Eddy Current Trolley detects surface breaking defects - collapsible and self-contained, can be setup in mere minutes without tools
  • Unique Probe designed to follow the shape of the top and gauge faces of the rail
  • Adjustable height rollers to ensure a constant gap between probe and rail, for smooth probe carriage
  • Sprung Diablo wheels ensure a good reference to the gauge face
  • 5.7" (145 mm) Large daylight readable display, user friendly interface, single level menu system, "quick function" sidebar
  • Rugged lightweight housing - 2.6 lbs. (1.2 kg)
  • 2 year standard warranty
  • Optional ETherCover extending warranty to 5 years


"Widescan" Rail Probe

ETher's widescan are used in conjunction with an with an ETher NDE portable flaw detector for rapid rail inspection. They can detect surface breaking flaws, lightness and overcome consistency problems associated with ultrasonic couplant and higher surface speed capability. 

Defect Sizing

The Rail probe, a single probe that is capable of detecting orientated flaws in one pass of the rail head, giving depth (size) of the flaw.

Rotary Encoder

A rotary encoder to provide distance information to the software and synchronize the sample rate with the speed.

Vector Display

"Trace" vs. "Vector" can be captured and when using Vector Display both data sets can be shown simultaneously.


How It Works

The Filus EC-1 is straightforward in use. The trolley is hand pushed along the track under test, at a normal walking pace, providing a highly accurate test of the rail surface. The operating parameters remain set for the majority of the operation, the only setup required is calibration against a known size slot in the test piece, then the unit is placed on the rail and the probe block lowered onto the surface. The system is then balanced (an automatic operation to null all readings on a clean section of rail), then the distance counter is reset and recording can start. The display will show data at the current point.
