On October 1-4, 2023 OKOndt GROUP attended Railway Interchange 2023 - the largest North American railway event. This time the exhibition took place in Indianapolis, Indiana, USA (Indiana Convention Center) and brought together over 700 exhibitors and more than 8, 000 visitors who are the major influencers in the industry. Thank you to everyone who was with us at the RI 2023!

Eddycon С Purpose

Eddy current flaw detector Eddycon C is referred to the testing and evaluation means. It is intended for manual testing by eddy current technique for the presence of surface and subsurface defects, such as discontinuity of the material (cracks, overlaps, holes, fine cracks, etc.).

See updated eddy current flaw detector

It is Applied in the Following Branches of Industry:

  • AIRCRAFT
    testing of aeronautical engineering parts (wheel disks, covering, turbine blades, multilayered constructions, holes of various kinds etc.);
  • OIL-AND-GAS
    testing of pipelines, turbine blades of gas-distributing station (GDS), pressure vessels, etc.;
  • CHEMICAL
    testing of pipelines, industrial tanks etc.;
  • POWER
    testing of steam generator pipes by inner bobbin eddy current probes, collectors etc.;
  • MACHINE BUILDING
    testing of rods, wire, metalwares, forming rolls, sheet metals etc.

Flaw Detector Advantages

Capabilities and Serivce Functions of the Instrument

  • Possibility of defects detection with the depth – from 0,1 mm and width – from 0,002 mm;
  • digital signal filtering (there are 5 filter types: Lowpass, Highpass, Bandpass, Differential, Averaging);
  • eddy current signal display:
    • a) complex plane (XY) – allows to detect defects among interferences by analyzing the signal waveform;
    • b) generation of two channels can be used for suppression of interfering factors and reduction of their influence on testing results (for mixing an operator can choose one of 4 algorithms: addition, subtraction, addition with horizontal inversion and addition with vertical inversion).

a)

b)

  • two modes of instrument operation: day mode is used when operating in dimly lit places with insufficient visibility; night mode is used when operating in places with bright lighting, to increase the display contrast;
  • time of flaw detector operation mode setup – up to 1 minute;

  • storage battery discharge level indication;
  • possibility of connection and operation of ECPs of the following types:
    • differential ECP;
    • differential ECP connected according to the bridge scheme;
    • differential ECP of transformer type with grounded centerpoint;
    • differential ECP of transformer type;
    • absolute (parametric) ECP ;
