Profile Select offers enhanced metal detection

Mettler-Toledo Safeline’s Profile Select rectangular metal detection systems offer sensitive detection capabilities for both wet and dry products on food production lines. The inclusion of variable frequency technology in the systems offers accurate inspection regardless of the moisture content of the product or packaging material. Traditionally, only dry products can be successfully inspected at metal detectors’ maximum sensitivity setting, as wet or “conductive” products create an electrical signal, called product effect, which can disguise the signal generated by metal contaminants. Until now, contaminant detection in such products uses metal detectors with tuned frequency technology. While these metal detectors can be configured to provide several operating frequencies to handle certain products, inspection flexibility is limited in cases where manufacturers produce a wider range of products. The Profile Select detectors using the variable frequency technology automatically deploy the most suitable frequency for each application with an auto-set function that determines the optimum frequency for the product being inspected. The operating frequency can be adjusted in small 1kHz increments, which ensures precise tuning for each application and allows products with differing size, moisture content and packaging material to be inspected on a production line.
