A first-of-its-kind metal detection platform from Thermo Fisher Scientific rapidly scans up to five frequencies to help food and consumer goods manufacturers find ferrous, non-ferrous and stainless steel metal contaminants in products to improve safety for their customers.

The Thermo Scientific Sentinel multiscan metal detector also enables users to identify contaminants that are up to 70 percent smaller in volume than previous technologies, including the Thermo Scientific APEX 500 metal detector.

The Sentinel metal detector is designed for a wide range of applications, including consumer health and beauty, dairy, meat and other foods. Inspecting these products for foreign objects is especially challenging because of what is known as “product effect,” where the signal from a particular type of metal can be hidden inside the electromagnetic response of the product. With prior technology, switching the operating frequency could make the hidden metal detectable, but could then make a different type of metal undetectable. Thermo Fisher designed the Sentinel to alleviate this problem by scanning multiple frequencies, increasing the probability of finding random sizes, shapes and types of embedded metal foreign objects.

Because the Sentinel metal detector has the same footprint and aperture location as the APEX 500 metal detector, users seeking to upgrade to the new platform can do so easily. The Sentinel metal detector will make its global debut at Pack Expo Las Vegas, Sept. 25-27, at the Las Vegas Convention Center, Las Vegas, booth C-2200.
