Mettler-Toledo M50 R-Series AdvancedLine metal detectors

Mettler-Toledo has introduced M50 R-Series AdvancedLine metal detectors which has been designed for food manufacturers of unpackaged and packaged, wet, dry or bulk products. The series combines improved detection performance with intuitive operation and secure connectivity, delivering a sensitive, compliant and future-ready metal detection platform.

The easy-to-use unit has been designed to detect the smallest of metal contaminants, and keep good products moving. Technologies such as eDrive PLUS when combined with 900 kHz frequency, can improve the field strength to deliver high sensitivity to detect the smallest wire and non-spherical metal contaminants. Algorithms such as 3S PLUS combined with AI-based machine learning help achieve maximum sensitivity to minimise the risk of product recalls and deliver safer products.

Metal detectors in the series include: M55R for detecting smaller, irregular-shaped metal contaminants in dry products such as pasta, savoury snacks and deep frozen produce (where thawing does not occur); M55RB for bulk products such as large sacks, bags of powder and cartons; and M56R for challenging applications such chilled, wet, dry, deep frozen/thawing and metallised film-wrapped products.

A 10.1-inch capacitive touchscreen provides clear visualisation and intuitive navigation. It operates with the responsiveness familiar from smartphones and tablet screens, even when the user is wearing gloves or when the screen is wet.

The introduction of the INFINITY Electronic Test System represents an advance in routine testing. Automation in production performance monitoring is designed to simplify test routines, improve consistency and reduce testing time. It can also run tests automatically without operator intervention.

Embedded Wi-Fi supports secure and simplified connectivity, giving users rapid access to system information through QR code functionality. Combined with improved Condition Monitoring software and simplified data transfer, the series is designed to support continuous operation and reduced disruption on the line.

Brand protection is also enhanced through new Radio-frequency identification (RFID) access control which supports individual user logins and access management for enhanced security. Detailed access records are stored locally or transferred through multiple communication protocols, including OPC-UA and EtherNet/IP.

Manufacturers have the option to take product safety and data security to the next level by integrating ProdX data management software from Mettler-Toledo.

Advanced connectivity and full system logging provide comprehensive traceability across testing, detection events and system status, supporting audit preparation and alignment with global food safety standards such as BRCGS and International Featured Standards (IFS).

A dedicated service QR code also provides fast access to maintenance and service support.
