METTLER TOLEDO X3305 Industrial Micro-CT X-ray Inspection System

Overview

The METTLER TOLEDO X3305 Industrial Micro-CT X-ray Inspection System is a high-resolution, compact inline inspection platform engineered for non-destructive quality assurance in regulated manufacturing environments. Leveraging dual-energy X-ray imaging and advanced reconstruction algorithms, the system delivers quantitative density contrast analysis at sub-millimeter spatial resolution—enabling reliable detection of foreign bodies embedded within sealed, multi-layered packaging—including metallized films, aluminum laminates, and opaque plastic trays. Unlike conventional single-energy systems, the X3305 employs optimized beam hardening correction and real-time pixel-level attenuation modeling to distinguish low-Z contaminants (e.g., calcified bone, ceramic shards, dense rubber) from high-Z materials (stainless steel, tungsten, leaded glass) with high specificity. Its 1.8-meter footprint integrates seamlessly into existing production lines without requiring structural modifications, supporting throughput rates up to 1,200 units per minute depending on product size and inspection criteria.

Key Features

• 20 W low-power microfocus X-ray generator—reducing thermal load, energy consumption, and long-term operational cost versus legacy 100 W systems while maintaining stable photon flux and image SNR.
• Ergonomic modular architecture with quick-release conveyor belts and tool-free removable protective curtains—designed for rapid sanitation cycles compliant with FDA Food Safety Modernization Act (FSMA) preventive controls.
• IP65-rated enclosure as standard; optional IP69K certification enables full-pressure hot-water and caustic-solution washdowns in wet-processing zones (e.g., meat deboning lines, dairy filling rooms).
• Touchscreen HMI with icon-driven workflow navigation—supporting multi-language UI (English, Spanish, German, Chinese), user role-based access control, and audit-trail-enabled parameter logging per 21 CFR Part 11 requirements.
• GMP-aligned hygienic design: sloped surfaces, zero-stagnation joints, FDA-compliant elastomers, and stainless-steel 316L frame conforming to EHEDG Doc. 8.2 and NSF/ANSI 169 Section 7.3.

Sample Compatibility & Compliance

The X3305 accommodates products ranging from 25 mm × 25 mm sachets to 300 mm × 200 mm cartons, with maximum height clearance of 120 mm. It supports rigid, semi-rigid, and flexible packaging—including vacuum-sealed pouches, blister packs, flow-wrapped confections, and thermoformed trays. Detection sensitivity is validated per ASTM F2974–22 (Standard Test Method for Detection Capability of X-ray Inspection Systems for Food Products) for stainless steel (≥0.3 mm Ø), glass (≥1.0 mm Ø), stone (≥1.5 mm Ø), and bone (≥2.0 mm Ø) under worst-case orientation. All firmware and calibration protocols are traceable to NIST-traceable reference standards, and system qualification documentation satisfies ISO/IEC 17025 and EU Annex 11 requirements for computerized system validation.

Software & Data Management

Equipped with METTLER TOLEDO’s proprietary INSPECTOR™ 5.2 software suite, the X3305 provides synchronized image acquisition, automated defect classification (via supervised machine learning models trained on >50,000 labeled samples), and statistical process monitoring (SPC) dashboards. Raw projection data is stored in DICOM 3.0 format; reconstructed cross-sections and volume-rendered datasets export to STL, VTK, or TIFF for third-party CT analysis tools (e.g., Avizo, VGStudio MAX). Audit trails record all operator actions, parameter changes, and rejection events with time stamps, user IDs, and digital signatures—fully compliant with FDA 21 CFR Part 11, EU GMP Annex 11, and ICH E6(R3) data integrity principles.

Applications

Primary deployment domains include: finished-product inspection of ready-to-eat meals, baked goods, infant formula, sterile pharmaceutical vials, and OTC tablet blisters; raw material screening of bulk powders and granules prior to blending; and post-process verification of seal integrity, fill level accuracy, and component presence (e.g., desiccant packets, tamper-evident seals). The system is widely adopted by Tier-1 suppliers certified to BRCGS Food Safety Issue 9, IFS Food v7, and USP Analytical Instrument Qualification frameworks.

FAQ

What regulatory standards does the X3305 meet for pharmaceutical use?

It complies with USP , EU GMP Annex 11, and 21 CFR Part 11 for electronic records and signatures—validated using IQ/OQ/PQ protocols aligned with ASTM E2500-13.
Can the system detect non-metallic contaminants in metallized packaging?

Yes—dual-energy subtraction and scatter correction algorithms enable reliable identification of glass, calcified bone, and high-density polymers even inside aluminum-laminated pouches.
Is remote diagnostics supported?

Yes—secure TLS 1.3 encrypted remote access allows METTLER TOLEDO Field Service Engineers to perform firmware updates, calibration verification, and troubleshooting without onsite intervention.
How often does the X-ray source require recalibration?

Annual performance qualification (PQ) is recommended; source output stability is monitored continuously via integrated photodiode feedback, with automatic drift compensation applied during image reconstruction.
Does the system support integration with MES or SCADA platforms?

Native OPC UA server implementation enables bidirectional communication with Siemens SIMATIC, Rockwell FactoryTalk, and SAP ME for real-time OEE tracking and SPC data ingestion.
