SYSTEM SQUARE Dual Energy X-ray Inspection Systems

SYSTEM SQUARE INC. is a Japanese inspection machine manufacturer established on 1 April 1989 and headquartered in Nagaoka, Niigata Prefecture. It develops equipment that detects foreign bodies and checks shape, count and mass for food, pharmaceutical, cosmetic and industrial products, helping manufacturers prevent recalls and meet food safety requirements.

Its SX2 series X-ray inspection systems include dual energy models that find low-density contaminants which conventional X-ray misses, high-sensitivity HW models with a new X-ray sensor, IP66 waterproof W models with an all-stainless HACCP-oriented body and large-product models. Besides foreign body detection in meat, poultry, fish, ready meals and aluminium-packed or canned goods, the machines run shape inspection, missing-product checks and relative mass estimation. Optional USB export and LAN networking let a PC manage several machines for traceability. The portfolio also covers metal detectors, X-ray seal inspection, magnetized metal detectors and rejectors.

• Dual energy X-ray: separates product and contaminant by two energy levels to catch low-contrast foreign bodies.
• HW high-sensitivity models: a new X-ray sensor gives stable detection and relative mass inspection.
• W wash-down models: IP66 waterproof and dustproof chamber with HACCP-compatible stainless design.
• Shape and missing-product checks: inspect form and absence of items alongside contaminant detection.
• Mass estimation: estimates relative mass from density for loose or continuously packed products.
• Data management: optional USB export and LAN network control of multiple machines from a PC.

• Seafood exporters checking fish fillets and frozen shrimp packs for bones and hard contaminants before shipping to Japan.
• Meat and sausage plants inspecting products for bone, metal and glass while verifying pack weight.
• Canned food and coffee producers inspecting aluminium-packed or canned goods where metal detectors are ineffective.

• Fewer missed contaminants: dual energy imaging detects foreign objects that conventional X-ray cannot.
• Several checks in one pass: foreign body, shape, missing product and relative mass inspection run together.
• Hygienic operation: W models have an all-stainless body and an IP66 inspection chamber for wash-down areas.
• Easy use and traceability: low-energy X-ray design needs no special operator qualification, and networked data supports traceability.

Retailers and importers increasingly require X-ray inspection to find bone, glass, stone and metal fragments in packaged food. Vietnamese and Southeast Asian exporters of meat, seafood, frozen and ready meals face stricter foreign body audits from Japan, the EU and the US, raising demand for inline inspection with data logging.
