Mettler-Toledo Safeline

Metal Detection Systems for Food and Pharma Producers

Performance metal detection systems

Mettler-Toledo Safeline is the global market leader for high-performance metal detection systems to enhance productivity, reduce product waste and optimise contaminant detection for food, beverage and pharmaceutical manufacturers worldwide.

The company forms part of Mettler-Toledo's product inspection division, which supplies metal detection, X-ray inspection, checkweighing and vision inspection technology. All solutions can be linked through the company's Prod-X data management software, ensuring 360° product inspection for manufacturing lines.

With safety legislation becoming ever more rigorous, it is essential for brand owners to have efficient and reliable product inspection systems in place to monitor their manufacturing lines for contamination. With over 23 years of experience producing metal detection systems, Mettler-Toledo Safeline estimates that its installed systems currently inspect more than one trillion food and pharmaceutical packages per annum.

Metal detector with variable frequency technology

Mettler-Toledo Safeline's most significant recent innovation is the Profile Select metal detector, which uses variable frequency technology to enhance metal detection in difficult applications. By automatically choosing the most suitable operating frequency for each application, the Profile Select ensures maximum metal detection sensitivity for both wet and dry products, including foods packaged in metallised film.

Metal detection systems with due diligence enhancements

Mettler-Toledo Safeline has developed a due diligence enhancement for its metal detection systems to strengthen food safety compliance and system security on food processing and packing lines. The due diligence enhancement delivers increased failsafe functionality to safeguard consumer welfare, including a fully automated rejection system that ensures products that are rejected cannot be returned to the conveyor.

Mettler-Toledo Safeline's metal detection product range is segmented into seven specific categories as utilised by both food and pharmaceutical producers.

Rectangular aperture metal detectors

Rectangular aperture metal detectors deliver unparalleled levels of sensitivity in metal contaminant detection. They are ideal for conveyorised products and general metal detection applications, and can be integrated with material handling and conveyor systems to provide fully automated product inspection.

Gravity fall metal detection systems

Mettler-Toledo Safeline gravity fall metal detection systems deliver unrivalled levels of detection sensitivity to all metal contaminants, and are ideal for the inspection of bulk powder, free falling powder and granular products.

Metal detectors for vertical packaging applications

T Series metal detectors are designed for installation in vertical packaging applications. They can detect metal contamination within product 'in-flight'; for example, as it passes from a weigher into a bag maker or packaging machine.

Pipeline metal detectors for liquid, paste and slurry products

L Series and HDS pipeline metal detectors are suitable for installation in food production environments where there is a need to inspect liquid, paste and slurry products as they pass through process pipelines.

Metal detectors for pharmaceutical tablets, capsules and powders

Mettler-Toledo Safeline pharmaceutical metal detectors are designed specifically to meet the exacting standards of the industry. They provide the ultimate solution for fully integrated product inspection and rejection for tablets, capsules and powders.

Conveyorised metal detection systems

Mettler-Toledo Safeline provides both standard and bespoke conveyor-mounted metal detectors. All of the company's rectangular metal detection heads can be integrated with standard or bespoke conveyor systems in order to fully automate product inspection processes.

Test samples for metal detection equipment

Regular testing of metal detection equipment is an essential part of any well-designed quality management system in the food or pharmaceutical industry.

Mettler-Toledo Safeline provides a comprehensive range of test samples for use in any metal detection application, including conveyorised inspection, gravity fall and pipeline systems.

When used as part of a rigorous QA procedure these test samples help to ensure that performance standards are being met. They can also be used to verify compliance with ISO certification requirements, country-specific retailer codes of practice, HACCP and GMP standards.

Winner of the Queen's Award for Enterprise

In 2012 Mettler-Toledo Safeline received the Queen's Award for Enterprise in the International Trade category for an outstanding level of export growth. The company's international success is driven by its expertise in developing high-performance solutions that meet customers' needs and enable them to comply with new safety legislation, such as the US 2011 Food Safety Modernisation Act and Germany's International Featured Standards (IFS) for Food version 6.

This award recognises the company's continual commitment to innovation, its expert support team and its performance in response to growth opportunities in the food, beverage and pharmaceutical markets.

Available White Papers


Understanding Challenging Applications for Improved Metal Detection 18 March 2015 In the food and pharmaceutical industries many of the products being inspected for contamination exhibit a phenomenon known as 'Product Effect'. This is where the type of product being inspected, can itself hinder the inspection technologies capability to identify that particular contaminant.


Calculating the Total Cost of Ownership for In-line Metal Detection 18 March 2015 If possible, all the costs connected with the new purchase should be taken into account. Whether large corporations or individual entrepreneurs, anyone who wants to assess an investment properly should estimate all the costs incurred.


Enhancing Levels of Due Diligence - Exceeding Standards in the Food Industry 08 May 2013 The manufacturing environment and general food processing can create the risk of metal contamination occurring. A metal detector often acts as a critical control point to mitigate this risk.
