Everything Eddy Current



The RailCheck Flaw detector is a hand-held Eddy current flaw detector, modified for specific rail inspection, and is easily partnered with a rail trolley and ETher NDE’s rail probes.

The FILUS EC-1 Trolley is a hand-pushed trolley, specially designed to check a single rail using Eddy current methods. The trolley uses a single eddy current probe and is capable of continuous inspection of the rail for defects which break the surface of the head of the rail. Inspection of the gauge corner and face for head checks is also possible due to the unique design of the probe.

The on-board RailCheck Eddy Current flaw-detector can be configured to trigger an audible and visual warning should a defect be indicated; the display shows the presence of potential defects in the rail and the complete inspection is continuously recorded for later analysis.

Industries & Applications


  • Single Rail Eddy Current Trolley to detect surface-breaking defects
  • 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 to ensure a good reference to the gauge face
  • User friendly interface, single level menu system, “quick function” sidebar
  • Large Daylight readable display 145mm (5.7”)
  • Rugged lightweight housing 1.2kg (2.6lbs)
  • 2 year standard warranty
  • Optional ETherCover extending warranty to 5 years


“Widescan” Rail probe

Ether’s “Widescan” Rail probes are used in conjunction 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 synchronise the sample rate with the speed.

Vector Display

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