Ultimate X-Ray Inspection Systems Guide: Principles, Operation & Maintenance | SameGram
Executive Summary
If you're searching for "what is X-ray inspection equipment," you've landed in the right place. X-ray inspection systems are advanced non-destructive testing tools that use penetrating radiation to reveal hidden contaminants, defects, or structural issues inside products without damaging them. Based on the principle of varying material densities absorbing X-rays differently, these X-ray inspection systems generate detailed images to ensure quality control in industries like food processing, pharmaceuticals, and manufacturing.
As a seasoned automation line electrical engineer with over 15 years in designing and optimizing production systems, I've seen firsthand how proper implementation of X-ray technology can slash defect rates by up to 95% and boost throughput. This guide draws from real-world applications, including my work integrating these systems into high-speed lines, to provide actionable insights for engineers, operators, and managers. We'll cover everything from basic physics to troubleshooting, with a focus on practical solutions that address common pain points like false positives or radiation safety concerns.
At SameGram, we specialize in X-ray inspection solutions tailored for food safety and industrial quality assurance. Our x-ray inspection systems, like the CSS series, incorporate self-learning algorithms that adapt to your specific products, ensuring reliable detection of contaminants as small as 0.3mm.

Chapter 1 - Fundamentals of Industrial X-Ray Inspection Technology
1.1 Working Principles of industrial X-ray inspection systems
X-ray inspection works by emitting low-energy X-rays through a product, where denser materials like metal or glass absorb more radiation, creating contrast in the resulting image. This is governed by the Beer-Lambert law: I = I₀ × e^(-μx), where I is the transmitted intensity, I₀ is the initial intensity, μ is the absorption coefficient, and x is the material thickness. In practice, this means a thin aluminum foil might require 40kV, while thicker products like bulk nuts could need 55-65kV for optimal penetration.
From our experience troubleshooting lines, voltage settings are critical—too low, and images are underexposed; too high, and you risk overexposure or unnecessary radiation. Our SameGram food X-ray inspection equipment automatically adjust tube voltage based on product thickness, drawing from real-time data to maintain consistency.
1.2 Core System Components
A typical X ray food inspection system includes:
● X-ray Tube/Generator: Produces beams at adjustable voltages (e.g., 40-65kV in our XSS Series for food applications).
● Collimator: Focuses the beam to minimize scatter.
● Detection Systems: Linear diode arrays capture images at high speeds, with integration times matched to conveyor speeds (e.g., 4000mm/min default in our units).
● Image Processing Unit: Uses algorithms like morphology (Lv1), brightness/darkness (Lv2), and gradient detection (Lv3) to identify anomalies.
● Sample Manipulation Platform: Conveyor with adjustable speed and direction for single-piece or bulk flow.
In SameGram's packaging-class multi-purpose detectors, components are shielded with thick steel plates to ensure safety, and self-learning features allow the food X-ray inspection equipment to mask non-contaminants like desiccants automatically after 8 learning cycles.
Chapter 2 - Industrial Applications & System Types
2.1 Manufacturing Sector Applications
In food production, these food X-ray inspection equipment detect metals, glass, stones, bones, or high-density plastics in packaged or bulk items. For instance, our high-speed bulk foreign object X ray inspection for food industry and color sorter integrated machine handles scattered materials like nuts, identifying defects in real-time with flap rejection mechanisms.
Pharmaceuticals benefit from package integrity checks, while automotive uses include weld verification. One client I worked with reduced contaminant recalls by 80% after integrating our intelligent high-definition X ray food inspection detector, which supports multi-channel modes for stacked products.
2.2 System Configuration Types
● Offline vs. Inline: Inline for continuous production (e.g., our CSS series supports up to 1000 product profiles).
● 2D vs. 3D CT: 2D for speed in food lines; 3D for detailed defect analysis.
● Real-time vs. Batch: Real-time with AI for immediate rejection.
Choose based on throughput—our units of X ray inspection for food industry excel in high-volume scenarios, processing images with 42500 stretch coefficients for clear visuals.
Chapter 3 - Pre-Operation Technical Checklist
Before powering up, run these checks to avoid downtime—I've seen unchecked grounding cause 30% of startup failures.
3.1 Power & Safety Verification
● Grounding integrity (<1Ω resistance).
● Emergency stop functionality (front-mounted button in our designs).
● Radiation leakage (<1 μSv/hour).
● Voltage stability (±10% tolerance).
3.2 Mechanical System Inspection
● Conveyor tension and alignment (max 20mm deviation/10min).
● Lead curtain integrity (no gaps).
● Cooling fans operational.
3.3 Imaging System Calibration
● Warm-up after shutdown.
● Detector gain curve reading (view offsets with X-ray off/on).
● Phantom test using ASTM standards.
For SameGram industrial x-ray inspection systems, calibration auto-completes at 100% progress upon startup.
Chapter 4 - Operational Procedures & Best Practices
4.1 Standard Operating Procedure (SOP)
1. Power on via key switch; software auto-launches.
2. Select product from library (up to 1000 entries).
3. Calibrate: Adjust voltage (40kV for thin products), start self-learning if new.
4. Run: Monitor real-time display; system rejects via push rods or flaps (e.g., 200ms action duration).
5. Stop and report: View logs for total good/bad counts.
Optimize parameters like sensitivity levels (higher for stricter detection) to minimize false rejects.
4.2 Common Defect Signatures & Analysis
● Bridging: Irregular shapes in images.
● Voids: Low-density spots.
● Use our Lv1 algorithm for area-based shielding (min area threshold) to ignore benign features.
In operation, our self-learning masks items like aluminum clips after 8 passes, with adjustable shield grades (20-60 for varying shapes).
Chapter 5 - Troubleshooting & Maintenance Protocol
5.1 Electrical Fault Diagnosis
● No emission: Check tube filament; reset emergency stop.
● Fluctuations: Verify mA (auto-adjusted in our software).
5.2 Mechanical Maintenance Schedule
| Frequency | Task | Details | ||
Daily | Clean belts | Remove debris to prevent interference. | ||
| Weekly | Check temperatures | Detector/X-ray below 52°C to avoid alarms. | ||
| Monthly | Gain curve verification | Read and adapt offsets. | ||

5.3 Image Quality Degradation Solutions
● Over-saturated: Disable enhancement or adjust stretch to 42500.
● No image: Check cut edges (for unilluminated detector ends) or clean channels.
If calibration fails, verify hardware connections (gray for normal in our interface).
Chapter 6 - Safety & Compliance Standards
6.1 Radiation Safety Protocols
Adhere to FDA and EU limits; our non-explosive designs use protective curtains—never insert body parts during operation. Personnel must use dosimeters; interlocks prevent access.
