Fortress Gravity - Metal Detectors are designed for use in free-falling applications to inspect a wide range of products including flour, rice, cereals, sugar, and powders or grains. Systems are available with a selection of pipe sizes and the Diverter Valve reject system is typically used to move contaminated product into a reject tank. Stealth Metal Detectors use powerful Digital Signal Processing technology and have high sensitivity levels to ensure the detection of the smallest ferrous, non-ferrous, and stainless steel contaminants. Custom manufactured to suit gravity applications, Stealth detectors are available in either stainless steel or aluminum construction. Built in data collection and Contact Reporter Software make them a critical control point in preventing product contamination. Renowned for their superior accuracy and reliability, Stealth Gravity Metal Detectors act as essential Critical Control Points in HACCP systems, effectively identifying and rejecting potential contamination.
