Eddy Current Flaw Detector – EDDYCON D

The EDDYCON D universal multi-channel eddy current flaw detector has been designed to solve an extensive range of tasks of eddy current flaw detection.

It is Applied in the Following Branches of Industry:

  • Oil-and-Gas
    Testing of pipelines, pressure vessels, turbine blades of gas-distributing station (GDS), etc.
  • Chemical
    Testing of industrial tanks, pipelines, etc.
  • Aircraft
    Testing of aeronautical engineering parts (covering, turbine blades, wheel disks, multilayered constructions, holes of different kinds etc.)
  • Power
    Testing of steam generator pipes by inner bobbin eddy current probes, collectors, etc.
  • Rail Transport
    Testing of rail components and car units (parts of wheel pair and axlebox unit, load trolley, automatic coupler, refrigerated carriages and coaches etc.)
  • Machine Building
    Testing of rods, forming rolls, sheet metals, metalwares, wire, etc

The flaw detector is an eddy current channel that uses the Ethernet port and is hence linked to stationary PCs, tablets or portable laptops. By using specially configured software, the detector develops high-performance systems for non-destructive testing.

The Flaw Detector Advantages and Distinctive Features

  • Rotary scanners connection
  • Up to 2 encoders connection
  • High frequency measurement
  • Data transmission via Wi-Fi channel
  • Superior performance due to the flaw detector multi-channeling
  • Ethernet port for two-way communication with PC
  • Capability to combine a number of EC channels when developing the automated testing systems
  • Availability of multi-functional software for flaw detection of various test objects (testing the pipe body, rolled products, wheelsets, rails, bars, wires, etc).
