New digital food metal detectors from Fortress Technology

Fortress Technology’s latest generation of digital food metal detectors feature the ARM microprocessors. Used in a range of devices, from smartphones to tablets and multimedia players, ARM Processing helps to run multiple inspection processes simultaneously, while capturing and storing processing data for traceability.

With the Interceptor metal detector, ARM processing enables a machine to run real-time analysis of a low-frequency and a high-frequency signal in parallel. This allows food producers to inspect wet or conductive products and identify the product effect.

Fortress is also utilizing the microchip power to improve the detection of thin flat metal flakes in high-value, low-profile foods. Using multiple coil sets to instantaneously drive the electromagnetic fields in different directions, the Interceptor DF scans and looks for signals over a broad spectrum. The stronger disturbance from one field compensates for the weaker signal from another.
