DY522 LEEB Ultrasonic Flaw Detector – Doryang

Application:

This instrument can detect internal defects (such as cracks, inclusions, pores, etc.) and automatically perform positioning, evaluation, and diagnosis.
It is widely used in laboratories, special inspection institutes, shipbuilding, oil and gas equipment, aerospace, military industry, chemical industry, power, steel, metallurgy, railways, automobile manufacturing, machinery, boiler pressure vessels, special equipment, petroleum pipelines, construction, mold manufacturing, universities, and other industries.
We have extensive experience in flaw detection for forgings, castings, plates, pipes, rods, and alloy steel tubes. Our customers are distributed across various regions, including special inspection institutes, steel structure testing centers, Wuhan Iron and Steel, Baosteel, Handan Steel, Shanghai Jiao Tong University, Daqing Oilfield, etc.

Main Functions:

• Automatically generates DAC and AVG curves using standard test blocks, with no restrictions on sampling points, and allows compensation and correction.
• Automatically displays echo-related parameters (Depth D, Horizontal P, Distance S, Amplitude H).
• Freely switch between three measurement scales (Depth D, Horizontal P, Distance S).
• 100 independent flaw detection channels, allowing free input and storage of industry-specific standards (expandable).
• Can store 300 A-scan images and parameters (expandable as per user requirements).
• Automatically calculates defect equivalent φ values and has a peak memory function.
• Two detection modes: Peak value and Edge detection.
• Three probe modes: Single crystal, Dual crystal, and Through transmission.
• Automatic damping matching, intelligent operation for fast flaw detection, and automatic gate alarm.
• Custom flaw detection procedures can be generated based on actual workpieces, eliminating the need to carry test blocks for on-site inspections.

Product Features:

• Powered by a lithium battery, with an 8-hour working time.
• Rugged, durable, waterproof, dustproof, and has strong anti-interference capabilities.
• High-brightness large screen display, suitable for flaw detection under sunlight or in tunnels.
• Gates: Entry gate and Loss gate.
• Single-gate and dual-gate readings.
• Built-in USB interface; insert an SD card to record the flaw detection process.
• Alarms: Buzzer alarm and LED light alarm.
• Features three-proof protection: waterproof, oil-proof, and dustproof, significantly extending service life, which is several times that of conventional flaw detectors.
