The Thermo Scientific™ Sentinel™ 4000 family of metal detectors, featuring Multiscan technology with up to five user-selectable frequencies of detection, provides improved sensitivity and detection of contaminants in food and other products.

Two models have been designed to address the needs of different applications. The drop-through system is well-suited for use with granular and powdered food products, cosmetics, and chemicals, while the pipeline system is engineered for slurries, emulsions, and other viscous or viscoelastic products.

The Sentinel 4000 systems can identify contaminants that are up to 50% smaller in size than the Thermo Scientific™ APEX Metal Detector. This helps manufacturers increase customer safety, improve product quality, and drive production efficiency.

Thermo Scientific Sentinel 4000 Systems come with Multiscan frequency technology that enables optimized performance in any application, with up to five user-selectable frequencies that allow for improved sensitivity and detection of smaller contaminants. This technology generates a higher probability of metal contaminant detection, leading to increased food safety and improved brand protection.

An easy-to-use touchscreen with setup wizards reduces setup time, and the controls allow simplified, harmonized operation aligned with the Sentinel platform.

A unique icon-driven interface with multilingual Help and Auto Learn functions makes the system widely accessible to users of diverse experience levels and backgrounds.

Detailed graphical display shows phases, rejects, quality test results, and detection thresholds to enable seamless fine tuning and troubleshooting.

MODBUS serial or Ethernet communications connectivity permits easy reporting, diagnostics, and remote maintenance support to maximize uptime.

All electronics are integral, so mounting is easy and flexible. All balance functions are implemented in the software, eliminating the need for manual hardware rebalance in the field.

Isolation transformers added to the power conditioner shield the metal detector from power line problems.

Fe, non-Fe, and 316 SS test pieces are included to fit specific applications.

The HD model is available in a 316 stainless steel housing to provide better surface corrosion resistance and improved resistance to temperature shock, making it suitable for cold product inspection applications.

All construction materials are FDA-approved.

Notable Sentinel 4000 Drop-Through System features

  • The Sentinel 4000D metal detector is an effective drop-in replacement for the earlier APEX model; your system can be easily upgraded in the field.
  • The system is available in Heavy Duty (HD) specifications.
  • A wide ambient temperature range assures reliable operation.
  • Field compression flanges minimize the metal-free zone.
  • Product line speed ranges from 80 m/min (262 ft/min) to 300 m/min (984 ft/min).

Notable Sentinel 4000 Pipeline System features

  • Heavy Duty (HD) model features a unique case design and epoxy fill for reliable use in thermal shock environments.
  • A High Temperature (HT) option includes a PVDF liner rated up to 80°C for handling heated products.
  • Operating speed ranges from 0 to 492 L/min (130 gal/min); a custom option with a longer extension spool is available for higher speeds.
  • AuditCheck metal detection performance verification system improves the audit process.
