Key features

Sensor Technology

The Sentinel II uses TOMRA's pulsed LED/sensor arrays technology combined with a simple user interface to give our customers control over the removal of a broad range of defects, discoloration, damage, and undersize product, while also removing foreign materials such as cotton stalks, corn cobs, stones, plastic, glass, metal, wood bone and animal matter.

An enhanced, patented, high-speed rejection system efficiently removes defective product and foreign material, operating at higher speeds than previous models.

The Sentinel II offers low, medium or high speed modes depending upon the specific application sort requirements. With three different sorter size offerings, the Sentinel II covers a wide capacity range of 40 - 200 tons/hour making it an ideal solution for the seasonal and year round processors seeking off-color, defect and foreign material control.
