Ultrasonic Flaw Detector DY500 – Doryang

DY500 Digital Ultrasonic Flaw Detector

The DY500 digital ultrasonic flaw detector enables fast, convenient, non-destructive, and accurate detection, positioning, evaluation, and diagnosis of various internal defects in workpieces, such as cracks, weld seams, pores, shrinkage cavities, inclusions, and folds. It is widely used in industries including power generation, petrochemicals, boiler and pressure vessels, steel structures, military, aerospace, rail transportation, automotive, and mechanical engineering. This device is an essential instrument in the non-destructive testing industry.

Main Functions

• Automatic probe calibration without manual calculation.

• Automatic display of echo-related parameters, including depth (D), horizontal distance (P), distance (S), and amplitude (H).
• 16 independent flaw detection channels, allowing storage of various industry standards.
• Storage capacity for 980 A-scan images.
• Four types of weld illustrations (I, V, U, X), enabling quick and intuitive reflection position judgment.
• Automatic defect equivalent diameter (φ) calculation.
• High sampling rate and low noise performance.
• Two probe modes: single-crystal and dual-crystal.
• Echo suppression function with warning light alerts.

Auxiliary Functions

• Chinese and English menu options.
• Gate sound and light alarm system.
• Automatic gain function to improve flaw detection efficiency.
• Two input methods for angle probes: probe angle and K-value.
• Peak memory and echo envelope function for quick identification of the highest echo.
• USB interface for PC connectivity, allowing data transfer and automatic flaw detection report generation.

Product Features

• Simple keypad layout and easy operation.
