  1. Salient Features of ‘da Vinci alpha’ / ‘da Vinci delta’ Digital Ultrasonic Flaw Detector

  2. Ideal for Thickness Survey / Corossion Monitoring

  3. Ideal for Thickness Survey / Corrosion MonitoringTest Range Starts from 2.5mm (in steel) • Better resolution / accuracy on lower thickness.

  4. Ideal for Thickness Survey / Corrosion MonitoringMeasurement Resolution of 0.01mm • Better Measurement Accuracy

  5. Ideal for Thickness Survey / Corrosion MonitoringEncoded B-Scan • Shows in graphical presentation cross-section of object thickness for easy identification of high corrosion.

  6. Ideal for Thickness Survey / Corrosion MonitoringEncoded B-Scan • Encoded x-axis data gives the precise location of each thickness measurement from a reference point .

  7. Ideal for Thickness Survey / Corrosion Monitoring“Minimum Thickness” Scan Mode • This scan mode enables detection of minimum thickness (highest corrosion) in each scanning.

  8. Ideal for Thickness Survey / Corrosion MonitoringMemory of Thickness Measurement Data • 20,000 thickness measurements. • 50 B-scan (of 500 readings each).

  9. Ideal for Thickness Survey / Corrosion Monitoring‘dvaSoft’ Software for Thickness Data Management For • Sequential • 2D and 3D configured file generation.

  10. Ideal for Thickness Survey / Corrosion MonitoringEcho-Echo Measurement • To eliminate / ignore coating thickness from thickness measurements.

  11. Ideal for Thickness Survey / Corrosion MonitoringTwo Independent Thickness Measurements • Two monitor gates offer independent thickness measurements to enable ‘High’ and ‘Low’ thickness alerts.

  12. High End, Accurate & Convenient Flaw Detection

  13. ToFD -Time of Flight Diffraction • Simple single channel ToFD feature. • * Available in ‘da Vinci delta’

  14. ToFD • Display : In Real-Time RF A-Scan & ToFD D-Scan. • Recording : Free Run or with positional Encoder for actual location. • Record Length : 1000mm test length with collection step of 1mm. Each A-Scan with 500 point depth. • Data Storage : Each Scan file is stored in external USB storage device with auto file naming.

  15. ToFD Data Analysis Software • Straightening of ToFD data using apex matching technique or by manually shifting of A-Scan is possible. • Defect marking of D-Scan image. • D-Scan data zooming control. • All A-Scan data can be exported to Excel for further analysis.

  16. High End, Accurate & Convenient Flaw DetectionColour Legs • Colour-coded display of legs during weld examination (angle probing) helps operator to identify skip distance.

  17. High End, Accurate & Convenient Flaw DetectionActive Peak Echo Dynamic • Echo dynamic envelope generated in red colour in the back ground with active / live A-scan in fore ground in different colour helps operator to identify the defect type.

  18. High End, Accurate & Convenient Flaw DetectionCurved Surface Correction • Trigonometric measurements while using angle probe on curved surface is accurate due to correction applied.

  19. International Standards Compliance for Flaw Size EvaluationFirst Echo / Interface Echo Triggering • This is useful during Immersion Testing.

  20. High End, Accurate & Convenient Flaw DetectionFour Narrow Bands • Tuned amplifier gives high Signal / Noise ratio. • a) 0.2 MHz – 1 MHz • b) 0.5 MHz – 4 MHz • c) 0.8 MHz – 8 MHz • d) 2.0 MHz – 20 MHz

  21. High End, Accurate & Convenient Flaw DetectionRF Display • Radio Frequency (RF) display for very high degree of measurement accuracy, probe characteristics evaluation and flaw characterization.

  22. High End, Accurate & Convenient Flaw DetectionAutomatic Test Range Calibration • It is faster, more accurate and easier than manual calibration.

  23. High End, Accurate & Convenient Flaw DetectionPulse Repetition Frequency (PRF) • It is possible to set PRF as low as 4 Hz to eliminate phantom / ghost echoes while testing large forgings etc…

  24. High End, Accurate & Convenient Flaw DetectionSimultaneous Display of Four Measurement Values • Selection of upto four measurement values for simultaneous display helps the operator in quick interpretation.

  25. High End, Accurate & Convenient Flaw DetectionWide Frequency Range (250 KHz to 20 MHz) • Frequency down to 250 KHz (0.25 MHz) enables testing of highly attenuative materials like composites, austenitic stainless steel etc.. • Probe with frequency up to 20 MHz on higher side can be used for checking low thickness jobs and for enhanced sensitivity.

  26. International Standards Compliance for Flaw Size Evaluation

  27. International Standards Compliance for Flaw Size EvaluationDAC Curves Complies with ● ASME ● ASME III ● JIS Standards

  28. International Standards Compliance for Flaw Size EvaluationDAC Curves • Multiple Curves with user selectable dB intervals (1dB to 14 dB). • Any of the curves can be set to trigger as flaw monitor gate.
