Overview
The Aolong T5777 Medium-Frequency Portable X-ray Generator Controller is an engineered solution for field-deployable radiographic non-destructive testing (NDT) of metallic and composite structures. Unlike conventional 50/60 Hz low-frequency X-ray generators, the T5777 employs medium-frequency inverter technology—operating at 2–10 kHz—to drive the high-voltage transformer. This frequency upshift enables significant miniaturization of magnetic core components and reduces eddy current losses, resulting in a compact, lightweight generator head with enhanced thermal efficiency and improved voltage regulation stability. The system delivers continuous, stepless kV adjustment from 100 kV to 300 kV and tube current control from 1 mA to 5 mA, supporting radiographic inspection across a broad thickness range—from thin sheet metal (≥1 mm) up to 48 mm of A3 carbon steel—without hardware reconfiguration. Its design adheres to fundamental principles of Bremsstrahlung X-ray generation, where electron beam energy (determined by kV) and flux (determined by mA) jointly govern photon spectrum intensity and penetration depth.
Key Features
- Medium-frequency inverter architecture (2–10 kHz) enabling >20% higher effective penetration capability versus legacy 50/60 Hz portable units
- Compact, integrated controller–generator topology with reduced mass and footprint—optimized for manual handling and confined-space deployment
- Continuous high-voltage adjustment (100–300 kV) and precise tube current control (1–5 mA) via digital feedback regulation
- Forced-air cooling system designed for sustained operation under ambient temperatures up to 40 °C; thermal load management validated per IEC 61331-1
- Wide-input power compatibility: operates stably on 220 V ±10% AC mains or mobile diesel/gasoline generators (minimum 4 kVA output capacity)
- Patented electromagnetic shielding layout minimizing stray radiation and RF interference—certified to EN 55011 Class B emission limits
Sample Compatibility & Compliance
The T5777 is optimized for radiographic imaging of ferrous and non-ferrous alloys, weldments, castings, and structural composites used in pressure vessel fabrication, pipeline maintenance, aerospace component repair, and railway infrastructure inspection. It supports standard industrial film (e.g., AGFA Structurix D7, Kodak Industrex M) and digital detector arrays (DDAs) compliant with ASTM E2737 and ISO 17636-2. Radiographic sensitivity meets ASTM E94/E1025 requirements for IQI visibility at specified kV/mA combinations. The unit complies with national safety standards GBZ 130–2020 (China) and incorporates interlock circuits aligned with IEC 61331-3 for operator protection. While not FDA-cleared for medical use, its radiation output characteristics are documented per ISO 4037-1 reference spectra for industrial calibration traceability.
Software & Data Management
The T5777 features an embedded microcontroller-based interface with LCD status display, real-time kV/mA readout, exposure timer, and fault diagnostics (e.g., overtemperature, arc detection, input undervoltage). No proprietary PC software is required for basic operation; however, optional RS-485/Modbus RTU communication allows integration into centralized NDT workflow platforms supporting audit-trail logging per ISO/IEC 17025 requirements. Exposure parameters—including date/time stamp, kV, mA, time, and operator ID—are stored locally for ≥10,000 events and exportable via USB-C for QA documentation. Firmware updates follow secure signed-binary protocols compatible with laboratory GLP/GMP record retention practices.
Applications
- On-site weld inspection in oil & gas pipeline construction and maintenance
- Field verification of casting integrity in wind turbine tower flanges and offshore platform joints
- Quality assurance of rail axle and bogie frame assemblies during overhaul cycles
- Emergency NDT response for structural damage assessment following seismic or impact events
- Mobile service support for remote manufacturing facilities lacking fixed radiography bays
FAQ
What is the maximum rated exposure time per shot?
The system supports single exposures up to 300 seconds at nominal 200 kV / 3 mA; duty cycle limitations apply above 250 kV to maintain thermal equilibrium.
Can the T5777 be used with computed radiography (CR) plates?
Yes—its stable output spectrum and reproducible timing enable consistent CR image quality when paired with phosphor imaging plates meeting ISO 11699-1 Class C requirements.
Is third-party calibration certification available?
Aolong provides factory calibration reports traceable to CNAS-accredited laboratories; users may engage ISO/IEC 17025-certified service providers for periodic field verification.
Does the controller support remote start/stop via external PLC signals?
Yes—dry-contact trigger inputs (24 V DC isolated) are provided for integration into automated inspection cells or robotic positioning systems.
What safety certifications does the T5777 hold?
It carries CCC mark (China Compulsory Certification), conforms to GB 15208.1–2018 for X-ray equipment safety, and satisfies electromagnetic compatibility per GB/T 18268.1–2010.
