Leeb510 Digital Ultrasonic Flaw Detector – Doryang

Product Overview:

The DY510 Digital Ultrasonic Flaw Detector enables quick, convenient, non-destructive, and accurate detection, positioning, evaluation, and diagnosis of various internal defects such as cracks, weld flaws, air pockets, shrinkage cavities, inclusions, and folds in workpieces. It is widely used in industries such as power, petrochemicals, boiler pressure vessels, steel structures, military, aerospace, rail transportation, automotive, and mechanical engineering. It is an essential instrument in the non-destructive testing (NDT) industry.

Key Features:

• High-precision quantification and positioning, meeting requirements for both near and far-range flaw detection.

• Small near-field blind zone, suitable for detecting flaws in small-diameter and thin-walled pipes.

• Automatic calibration with one-touch operation—automatically measures probe “zero point,” “K value,” “front edge,” and material “sound velocity.”

• Automatic defect echo display, showing depth (d), horizontal position (p), distance (s), amplitude, equivalent dB, and aperture (ф value).

• Three measurement scales (depth d, horizontal p, distance s) can be freely switched.

• Automatic gain, echo envelope, and peak memory functions to enhance flaw detection efficiency.

• Φ value calculation for straight probe detection in forgings—automatically converts maximum flaw echo into aperture value.

• 100 independent flaw detection channels (expandable)—allows custom storage of industry-specific standards, eliminating the need for test blocks on-site.

• Storage and playback of up to 500 A-scan waveforms and data.

• Automatic DAC and AVG curve generation, with customizable segmentation, unrestricted sampling points, and correction and compensation features.

• 13 built-in adjustable flaw detection standards.

• Customizable industry-standard inputs.

• Adjustable transmission pulse width and intensity.

• PC connectivity for data management with export options in Excel and A4 report format.

• IP65-rated aluminum-magnesium alloy housing, rugged, waterproof, dustproof, and interference-resistant.

• 260,000-color high-brightness display, with adjustable brightness for strong and low-light environments.

• High-performance eco-friendly lithium battery supporting continuous operation for 10 hours.

• Real-time clock recording for flaw detection date and time tracking.

• Power failure protection ensuring stored data is not lost.

• Automatic or preset flaw detection parameters.

• Digital suppression (0–80%) without affecting gain or linearity.

• Gain compensation to correct dB attenuation caused by surface roughness, curved surfaces, and long-distance flaw detection in thick workpieces.

This true three-proof design (waterproof, dustproof, oil-resistant) ensures durability in complex field and outdoor conditions, extending the lifespan of the flaw detector.

Additional Functions:

• Two input methods: Angle and K-value.

• Echo count analysis.

• Power status indicator.

• Sound and light alarm for gates and DAC.

• Screen freeze and unfreeze functions.

• Clock display.
