NextGuard C500: X-Ray inspection system

Thermo Scientific™ NextGuard™ X-Ray Detection Systems identify metallic and non-metallic foreign objects while eliminating “wet” product effects associated with metal detectors. NextGuard systems are designed for a wide range of food and pharmaceutical applications and provide expanded capabilities for inspecting packaged products for missing pieces or components, under and over-fills, and other quality issues using easily customizable vision software.

The Conveyor and C500 versions are user-friendly, cost-effective, and meticulously built systems that remove common hurdles to transitioning from metal detection to X-Ray inspection.

Features of the updated NextGuard X-Ray Detection System:

  • Users of product verification software can perform a variety of size, position, and count checks
  • Additional algorithms focus on detecting less dense impurities like glass or rocks in complicated, textured items like nuts or tea bag cartons.
  • Optional mass estimation software utilizes the density information in the X-Ray image to calculate weight and detect under/overfilled products.
  • Configurable for dual rejection, which distinguishes contaminated items from other quality faults
  • The standard system CPU is now six times quicker than the first-generation NextGuard system, allowing for faster contamination identification and inspection while improving user response.
  • The optional 0.4 mm-pixel detector provides 3.2 times higher resolution for increased metal detection in lightweight, homogenous products like powders or cheese.

Additional benefits

  • Compact size allows for easy installation and use
  • A unique non-linear detector that eliminates inspection blind spots
  • Removable conveyor for easy directional changes and maintenance
  • Intuitive Thermo Scientific™ VersaWeigh™ user interface and software
  • Modular design for excellent dependability and rapid diagnosis and repair
  • Source and detector lifetime indications to prevent costly downtime
  • Built-in remote monitoring for swift troubleshooting

Options for customizing the system

  • Radiation safety meters
  • UL or CSA site inspection
  • Spare parts kits
  • Complete rejection systems or rejection mechanisms for use with downstream conveyors
  • Stainless steel air conditioner designed for washdown settings
  • Alarm horn, no lead curtains, casters, guide rails
