Sentinel 4000 Drop Through System

The Thermo Scientific Sentinel 4000 Drop Through System, or Sentinel 4000D, featuring multiscan technology with up to five user-selectable frequencies of detection, provides improved sensitivity and detection of contaminants in drop through applications including granular and powdered food products, cosmetics, and chemicals. With the ability to scan multiple frequencies through simplified touch screen controls from 50 to 1000khz, the Sentinel 4000D provides the highest levels of food safety and brand protection.

The Sentinel 4000 drop through system will help manufacturers increase customer safety, improve product quality, and drive production efficiency. Its multiscan frequency flexibility 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 set-up wizards reduces set-up time, and the controls allow simplified harmonized operation aligned with the Sentinel platform.

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

The Sentinel 4000D metal detector complies with hazardous location regulation ATEX 22 (EU); Class II Division 2 (NA). The complete system is supported by a hazardous location assessment report (issued by an independent test firm; application requirements can be discussed). It comes with IP ratings of IP69K for head/controller, and IP65 for the full system.

Detailed graphical display shows phases, rejects, quality test results, and detection thresholds to enable seamless fine tuning and troubleshooting. All electronics are integral, so mounting is easy and flexible. All balance functions are implemented in the software, and thus there is no need for manual hardware rebalance in the field.

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

Notable Sentinel 4000 drop through system features:

• The Sentinel 4000D metal detector is an effective drop-in replacement for our 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 reliability of operation.
• Fe, non-Fe and 316 SS test pieces are included to fit specific applications.
• All construction materials are FDA-approved.
• 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).
• Isolation transformers added on to the Power conditioner shield the metal detector from power line problems.
