UD3-103EC

 

UD3-103EC is a hand-operated ultrasonic flaw-detector “Peleng” series. It makes possible detection and sizing of inner flaws in metallic and non-metallic materials, also in welding. It has modification UD3-103EC, combining ultrasinic and eddy-current testing.

Nonvolatile memory can store presets, scans and reports, secured by password from change or deleting.

Flaw detector can be connected to PC, and all data can be transferred to hard drive.

Flaw-detector is produced in several editions for use in gas and oil industry, ship-building, also universal edition for general purpose.

All flaw-detectors “Peleng” series are officially approved for use in Russia, Ukraine, Belarus and Kazakhstan.

 

 

SUPPLY SET:
  • "Universal" edition
  • "Oil and Gas" edition
  • "Shipbuilding" edition
  • “Acceptance Control” edition

 

Special editions:

  • “Oil and Gas” edition for pipelines;
  • “Ship-building” edition;
  • “Acceptance control edition” for railway wheels and axles.

 

 

Data display:

  • A-scan (freeze screen, magnify, …);
  • B-scan (ultrasonic cross-section display);
  • W-scan (basic beam tracing display for angle beam probe);
  • flaw parameters (coordinates, equivalent size, detection coefficient, pulse amplitude) – measured pulce is marked by “smart” mark (has no analogs!);
  • manual flaw sizing (with manual mark);
  • two independent gates, realizing pulse-echo, through-transmittion or backwall-echo methods;
  • sound and light alarm (alarm can be prolonged in order not to miss short signals from small flaws).

Automatic algorithms:

  • automatic time-base optimisation;
  • sound velocity automatic set in correspondence to the material, wave mode and beam angle;
  • automatic set of pulse repetition frequency;
  • distance meter zero automatic calibration by the reference signal;
  • automatic distance meter and sensitivity set.

Service modes:

  • freeze screen – keeps the current display;
  • envelope – the pulses of the A-scan “paint” over the screen;
  • magnify – zoom a part of the A-scan;
  • RF-signal – displays A-scan non-rectified;
  • curvature – automatic considerates the curved test piece surface.

Eddy-current mode:

Eddy-current mode combined with ultrasonics in the same instrument (has no analogs!) lets to detect surface and subsurface flaws (for example, cracks about several micrometers wide) in electroconductive materials.

Features:

  • frequency – up to 100 kHz;
  • testing modes – dinamic and static;
  • report can be saved and transferred to PC.

   

Thickness-gauge mode:

  • indication step: 0,01 mm;
  • minimum measured thickness: 0,8 mm;
  • “zero-backwall” or “backwall-backwall” measurement method;
  • A-scan for precise measurement in difficult cases (high attenuation, noise, coatings, etc.)

Nonvolatile memory:

  • saves A-scans, B-scans and work reports;
  • can contain 400 presets;
  • presets protected from change with passwords;
  • creates and saves “sets of presets” for multi-stage testing (has no analogs!);
  • all data can be transferred to PC.

 

Built-in-DGS-graph allows:

  • to set nesessary sensitivity;
  • automatically measure the equivalent size of any flaw;
  • set sensitivity side-drilled hole, backwall or cilinder concave surface of any size and in any distance;
  • automatically set time-gain or DAC.
