Mettler Toledo Safeline Profile Select metal detector for wet and dry products

Mettler-Toledo Safeline’s Profile Select metal detector offers sensitive detection for both wet and dry products on food production lines. The inclusion of variable frequency technology 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. This is because wet or ‘conductive’ products create an electrical signal called a ‘product effect’ that can disguise the signal generated by metal contaminants. Until now, contaminant detection in wet and dry products used metal detectors with tuned frequency technology. These metal detectors can be configured to have a number of operating frequencies to address specific products. However, this can restrict inspection flexibility in cases where manufacturers produce a wide range of products.

The detectors have true variable frequency technology that automatically selects the most suitable frequency for each application. The machine’s auto-set function selects the optimum frequency for the product being inspected, providing maximum product quality, enhanced process flexibility and optimised equipment performance.

Profile Select allows the operating frequency to be adjusted in 1 kHz increments, ensuring precise tuning for each application. This allows a variety of products with differing size, moisture content and packaging material to be inspected on the same production line without sacrificing inspection accuracy.

Profile Select rectangular detectors are designed for easy integration with conveyorised systems to fully automate inspection processes. Manufacturers can choose between various automatic reject mechanisms depending on the line and pack speed, pack weight and dimensions and the nature of the packaging material.
