Metal gets Detected. Food Production stays Protected.

Sentinel 4000D Drop Through Metal Detector

Brochure >


The Thermo Scientific™ Sentinel™ 4000 Drop Through System, or Sentinel 4000D, provides fast, accurate metal detection so you can protect against dangers inherent in raw goods harvested from the field and products prepared, sliced, or shaped by metal equipment. The Sentinel 4000D system increases the probability of finding ferrous, non-ferrous, and stainless-steel contaminants in food and other products. 


  • Advanced detection technology, a color touchscreen, connectivity, and more! 

  • Multiscan technology enables increased sensitivity and detection of smaller contaminants. 

  • An easy-to-use color touchscreen with set-up wizards reduces set-up time and simplifies control. 

  • Modbus serial or Ethernet communications connectivity permits easy reporting, diagnostics, and remote maintenance. 

  • Complies with hazardous location regulation ATEX 22 (EU); Class II Division 2 (NA, coming soon). 


With the Sentinel 4000D system, you can protect a wide range of products from unwanted metal contaminants: 

  • Granular foods like sugar or spices 

  • Powdered goods like silica for cosmetics 

  • Raw food items like nuts, fruits, or vegetables 

  • Chemical components like polystyrene beads 


The Sentinel 4000D is a robust metal detector with rapid response, standing guard over your production line to catch contaminants before they drop into the food supply.
