Aolong T6777 Portable High-Frequency X-ray Radiography Controller

Overview

The Aolong T6777 Portable High-Frequency X-ray Radiography Controller is a compact, field-deployable high-voltage DC generator designed for industrial non-destructive testing (NDT) applications. Engineered around a digital signal processor (DSP)-based control architecture, the system delivers precise, real-time regulation of tube voltage and current—enabling consistent X-ray output across variable inspection conditions. Unlike conventional low-frequency or half-wave rectified systems, the T6777 employs high-frequency inverter technology to generate stable, ripple-free DC high voltage, resulting in improved beam quality, reduced exposure time, and enhanced image contrast. Its design prioritizes operational safety, electromagnetic compatibility (EMC), and thermal resilience—making it suitable for use in remote infrastructure inspections, pipeline weld verification, aerospace component screening, and field-based pressure vessel assessments.

Key Features

• DSP-driven closed-loop feedback control ensures ±1% tube voltage stability under dynamic load and ambient fluctuations.
• Digitally selectable tube voltage and current (1–3 mA continuous range) allow fine-tuned optimization for material thickness, density, and detector sensitivity.
• High-frequency inverter topology minimizes transformer size and weight while maintaining >85% electrical efficiency at rated load.
• Forced-air cooling system enables sustained operation in ambient temperatures from −30 °C to +40 °C without performance derating.
• Integrated safety interlocks comply with IEC 61331-1 (Protective Devices for Medical X-ray Equipment) and incorporate dual-channel emergency stop, overvoltage cutoff, and thermal shutdown.
• Compact controller unit (8 kg net weight) features ruggedized aluminum housing, IP54-rated ingress protection, and ergonomic carry handle for single-operator deployment.

Sample Compatibility & Compliance

The T6777 is compatible with standard industrial X-ray tubes rated for up to 300 kV (tube-specific limit), including tungsten-target and molybdenum-anode configurations. It supports both film-based radiography and digital detector array (DDA) systems—including amorphous silicon flat panels and CMOS-based real-time imaging detectors—via synchronized exposure triggering. The system conforms to ISO 5579:2019 (Non-destructive testing — Radiographic examination of metallic materials using X- and gamma-rays — Basic rules), ASTM E94/E94M (Standard Guide for Radiographic Examination), and EN 462-1 (Image quality indicators). All operational parameters—including exposure time, kV, mA, and SFD—are traceable and loggable to support ASNT Level II/III reporting requirements and internal QA/QC documentation.

Software & Data Management

The controller includes an embedded LCD interface with intuitive menu navigation and real-time parameter display (kV, mA, exposure time, accumulated dose, and thermal status). Optional USB-C and RS-485 interfaces enable integration with third-party NDT data acquisition software (e.g., EFILM, D-Tect, or custom LabVIEW-based systems). Exposure logs—including timestamp, operator ID, job number, and environmental metadata—are stored internally (10,000-event capacity) and exportable as CSV or XML for audit-ready reporting. While not FDA 21 CFR Part 11-certified (as it is not a medical device), the logging architecture supports GLP/GMP-aligned record integrity practices through write-once storage and tamper-evident file hashing.

Applications

• Field inspection of welded joints in oil & gas pipelines, offshore platforms, and rail track components.
• In-service evaluation of castings, forgings, and composite structures in power generation and heavy machinery sectors.
• Pre-commissioning verification of pressure vessels, heat exchangers, and boiler tubing per ASME BPVC Section V.
• Real-time radioscopic monitoring during repair welding or brazing process validation.
• Educational and vocational NDT training environments requiring portable, repeatable, and safe X-ray source control.

FAQ

What is the maximum recommended tube voltage for the T6777 controller?
The T6777 is designed to drive industrial X-ray tubes with nominal ratings up to 300 kV; actual maximum voltage depends on connected tube specifications and cooling capacity.
Does the controller support pulsed or intermittent exposure modes?
No—it operates in continuous DC mode with 1:1 duty cycle; pulse modulation requires external timing hardware or compatible tube head firmware.
Can the T6777 be used with computed radiography (CR) phosphor plates?
Yes—its stable output and adjustable exposure parameters are fully compatible with CR readers meeting ISO 17636-2 image quality criteria.
Is calibration certification included with shipment?
Each unit ships with a factory calibration report (traceable to CNAS-accredited standards); annual recalibration is recommended per ISO/IEC 17025 guidelines.
What safety certifications does the T6777 hold?
It meets CE marking requirements under the EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU; type test reports available upon request.
