Rail Ultrasonic Flaw Detector
Detail Information
Overview
The GT-2+ Rail Ultrasonic Flaw Detector is a next-generation upgrade of the proven GT-2 platform. Fully compliant with TB/T 2340-2012 ("Ultrasonic Flaw Detectors for Rails"), it delivers high-accuracy, real-time defect detection for rails ranging from 43 kg/m to 75 kg/m—making it ideal for mainline, heavy-haul, and urban rail networks worldwide.
Basic Parameters
⚪ Multi-Channel Intelligence
🔹 9 standard detection channels + 2 dedicated verification channels
🔹 Independent gain control per channel for optimal sensitivity
⚪ Advanced Visualization
🔹 Supports A-scan, B-scan, and A/B dual-display modes
🔹 Real-time waveform rendering with flaw location (horizontal distance) and depth
⚪ Smart Alarming System
🔹 Multiple alarm types: gate-based, dual-channel coincidence, speed-triggered, and coupling-loss alerts
🔹 Audible + visual warnings with on-screen echo display for rapid decision-making
⚪ Rail-Adaptive Calibration
🔹 Auto-calibrates for 43 / 50 / 60 / 75 kg/m rails
🔹 Adjustable probe parameters (front edge, gate position, width) via intuitive software
⚪ Field-Ready Performance
🔹 12 V DC lithium-ion battery pack – lightweight and rechargeable
🔹 ≥8 hours continuous operation
🔹 Total system weight: 27 kg (including trolley, main unit, battery & charger)
⚪ Proven Detection Capability
