FD-GT-20 Digital Ultrasonic Rail Flaw Detector with 10-Channel TFT Display

The HUATEC FD-GT-20 rail flaw detector is the third generation of Goworld's all-digital products with TFT color display and lightweight trolley used for railway systems. Compliant with TB/T 2340-2012 UT Rail Tester standard issued by Ministry of Railway (China), this equipment is capable of detecting flaws in rails ranging from 43~75kg/m in type.

The system provides comprehensive detection of damage to all major parts of the rail, including:

• 2 70° probes scan the left side of the rail head
• 2 70° probes scan the middle of the rail head
• 2 70° probes scan the right side of the rail head
• 2 37° probes scan rail waist (screw cracks and other oblique cracks)
• 1 0° probe scans the rail head, rail waist, rail bottom, screw hole horizontal crack

• Trolley frame is compact, durable and easy to maintain
• Large-capacity integrated toolbox water tank (20L capacity)
• Integral lifting probe holder for easy probe removal and replacement
• Industrial three-proof touch panel (dustproof, waterproof, shockproof)
• Excellent performance indicators compliant with relevant standards
• Supports GPS positioning, data cloud storage, and automatic speech recognition
• Customizable ultrasonic operation terminal based on customer needs
