Improvements to the PowerPhasePRO software platform for metal detection in food applications have led to “the world’s most sensitive metal detector,” claims manufacturer Mettler-Toledo Safeline.

The upgrade, designed to serve modern highly automated food production plants and their current and future compliance requirements, will help manufacturers to lift productivity, cut manufacturing costs, and improve their competitiveness, said the company. “The new software package and additional ancillary equipment takes metal detection technology to an even higher level of sophistication providing food manufacturers with real benefits to address the challenges of an increasingly demanding market​,” it added.

Combining multiple and ultra high frequency operation, optimised vector and noise control algorithms, and multi-channel technology is said to have improved detection sensitivity by up to 50 per cent compared with competitor products. “Even irregularly shaped and difficult to detect non-magnetic stainless steel contaminants in wet or conductive products can be readily detected.​”

Operational efficiency

The metal detection software is claimed to incorporate a “unique​” change-free mode, which enables the individual profile of multiple products to be clustered together and inspected at a single setting. This is claimed to eliminate set-up time and maximize operational efficiency.

The system’s condition monitoring feature constantly assesses the performance and operation of key detector elements and gives advanced warning of changes which could cause downtime if unremedied. Messages from the condition monitoring system are displayed on a touch screen display unit. “The early warning of potential problems before they escalate enables maintenance routines to be conducted outside normal production time for maximized uptime and production capacity​,” according to the company.

Key messages from the metal detectors can be communicated directly to individuals via a GSM gateway communication system. This allows the detector to send SMS text messages and emails to operators and managers.

Safety standards

The PowerPhasePRO represents the future of product inspection and effective metal detection​,” said Mike Bradley, the company’s head of sales and marketing. “We have spent a lot of time working closely with the major food safety standards organizations and leading retailers in order to understand their needs and expectations​.

We have also listened carefully to our customers regarding their challenges and the issues which keep them awake at night. The PowerPhasePRO software enhancements we have developed are based on those requirements and will enable users to meet and exceed all quality standards and achieve compliance with food safety audits​.”
