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

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


  • High performance due to the flaw detector multi-channeling;
  • capability to combine several EC channels when creating the automated testing systems;
  • high frequency measurement;
  • data transmission via Wi-Fi channel;
  • ethernet port for two-way communication with PC;
  • rotary scanners connection;
  • up to 2 encoders connection;
  • availability of multi-functional software for flaw detection of various test objects (testing the pipe body, rolled products, wheelsets, rails, bars, wires, etc).

Specially configured software for operation with the EDDYCON D eddy current channel includes:

  • Program for setting up the EC channel;
  • Program of testing;
  • Program for reviewing the testing results.

Program for Setting up the EC Channel

Figure 1. Interface example of a program for setting-up the EC channel

This software ensures the following:

  • Rapid set up of all EC channel parameters: EC probe frequency, generator output voltage, gain, filters, threshold level type, encoder, etc.
  • Four independent threshold levels for automated defect triggering (ALARM) for each displayed area;
  • Saving the testing setups into the PC or tablet`s memory;
  • Estimating the defect depth and length;
  • Channels mix.


Program of Testing

Figure 2. Interface example of program of testing

This software ensures the following:

  • EC probes per channel display;
  • Real-time display of EC probe information (time charts, complex plane, two-dimensional display);
  • Recording the testing results into the PC or tablet memory;
  • Displaying the status of mechanisms and units on the mnemoc scheme;
  • Testing process control, shop mechanization (when designing automated NDT systems).

Program for Reviewing the Testing Results

This software ensures the following:

  • Reviewing the testing results from the database, sorting and retrieval by various characteristics;
  • Generating the testing protocols;
  • Archiving the testing results;
  • Reviewing the testing results from the remote PC, etc.
