For a wide variety of packaged / unpackaged products

Fortress Metal Detectors use a robust rectangular head to scan products transported through the aperture via a conveyor belt in food processing and packaging applications. For installation convenience and maximized system performance, Fortress offers the complete all-in-one detection solution with an integrated Vector Conveyor system.

Standard detectors are available in a wide range of aperture sizes or made-to-order with a selection of construction options including painted aluminum, stainless steel, and BSH extra-rugged casing.


Large Bag

For dry products in 50-110 lb bags (25-50 kg)

Fortress Large Metal Bag Detectors are perfect for larger sized products between 50-100 lb (25-50 kg. Popularly known as the “Big Bag King”, the system is able to detect 2.0 mm stainless steel in most bulk packs – an industry-leading sensitivity level!The Large Bag system achieves this production performance level thanks to its specialized coil structure and advanced electronics. It is the only system in the world to use a special RF (radio frequency) noise reduction modification, which dramatically reduces the detector’s susceptibility to RF interference.

For installation convenience and maximized system performance, Fortress offers the complete all-in-one detection solution with an integrated Vector Conveyor system.


Freefall – Bulk

For loose freefalling products such as powders and grains

Gravity metal detectors are the ideal incorporation into existing systems where bulk product, such as flour, rice and cereal, is free falling. The product under test is gravity-fed through a pipe system and travels through the detector’s aperture.Gravity systems typically include an automatic reject system to remove contaminated product from the flow, ensuring product that only the highest quality product is packaged for distribution.


Freefall – Packaged

For freefalling products prior to packaging

The Vertex system services the needs of retail products that are packaged in pouches or bags, such as chips and frozen vegetables. The slim Vertex can be installed in spaces with limited height and is utilized prior to final packaging. The unit is often placed below a Multihead weigher, or integrated with a Vertical Form Fill Seal machine for optimum performance. The wired remote control panel can be mounted in a more accessible area, allowing for easier operation.Vertex is the best-suited solution for applications where packaging is metallic or too large for standard detectors.



For product typically pumped through pipes

Pipeline systems are used for unpackaged items that are conveyed through the production process in a pipe. Due to the wet product application, Pipeline metal detectors are equipped with BSH Rugged Casing and Stainless Steel construction for IP69K certified protection, which ensures products maintain their quality while maintaining a safe operating environment.Pipeline systems are generally inserted into an existing process line at the last possible point. In the majority of cases, these products are pumped liquids and pastes however, the same principles can be used for other applications where the product is dry and blown through a pipe, for example sausage meat.


Vent Tube

For filled plastic and glass bottles

Vent Tube detectors are ideally suited for integration into existing bottling lines for detection of filler vent tubes. It’s typically positioned on the outfeed of a bottle processing or filler machine with easy interfacing to line controls and inspection systems. The system can be linked into existing fill level and monitoring equipment to provide an accurate detection of a vent tube nozzle within the product.
