Sentinel 5000 Multiscan Metal Detector 

The Sentinel 5000 model is the first multiscan metal detection platform to scan a combination of up to five user-selectable frequencies to find all random sizes, shapes and types of metal foreign objects. Sentinel 5000 identifies contaminants that are up to 50% smaller in volume than the Thermo Scientific™ APEX 500 metal detector, and has the same dimensions and conveyor mounting for easy upgrade.  The Sentinel 5000 can be used in a metal detection-checkweighing combination system, but due to its size must be mounted on a standalone infeed conveyor.

Sentinel 3000 Multiscan Metal Detector 

Choose the more compact Sentinel 3000 model for metal detection-checkweighing combination systems. Sentinel 3000 can be integrated into Thermo Scientific™ VersaWeigh™ and Versa GP checkweigher, reducing the total footprint while combining important functions like program changes, alarms and rejection statistics. Sentinel 3000 detects contaminants up to 35% smaller in volume than the Thermo Scientific™ APEX 300.

Sentinel 1000 Selectscan Metal Detector

Selectscan technology enables food processors to have an easy way to rapidly identify the single best frequency for an application. It tunes out product effect and adapts results to account for temperature changes and electromagnetic interference. At the same time it provides documentation of results from each production run. It is a completely new and holistic approach.

All models offer the following features to achieve the highest level of food safety:

  • Frequency Range 50 to 1000 kHz, multiscan runs up to five frequencies
  • Easy-to-use touchscreen with new Autolearn function to quickly optimize set-up
  • Detailed graphical displays for phase, rejects, quality test, and detection thresholds to enable easy fine tuning and troubleshooting
  • IP69K for severe washdown and dust, eliminating repair costs
  • All electronics are integral, so mounting is easy and flexible
  • All balance functions are implemented in software, so no need for manual, hardware rebalance in the field
  • Wide ambient temperature range assuring reliability
  • Fe, non-Fe and 316 SS test pieces included to fit specific application
  • In combos the user interface is available on the metal detector AND the checkweigher screens
