The amazing thing that Fortress Technology has done for the field of metal detecting is to design a system that allows metal detectors to inspect free falling products such as rice, cereals, powders, corn and other snack foods prior to packaging. This is big news in the metal detecting industry because it can provide optimum metal detector performance and brand protection, while improving useful in applications where testing is made more difficult due to access, position, product flow or environmental conditions. The state of the art HALO automatic test system was designed to harness the signal generated by a conductive loop outside of the detector which receives signals through the air from the machine’s transmitter coil and when the loop is closed or opened, the change of signal flowing through the loop causes a disturbance on the detector’s receiving coil. Phil Brown, sales director at fortress technology states, “There are a number of automatic test systems available on the market, but these are often very complicated electromechanical devices that are prone to failure themselves. Plus they do not allow for multiple test levels.”
The result logging of the HALO test systems can be done manually as well as normal, but can also be system so that exact time and results can be stored and monitored. Established in the UK since 1999, Fortress technology provides an extensive range of metal detecting systems to a variety of industries with primary focus on food and pharmaceutical.
