Europe: Mettler-Toledo enhances metal detectors


Mettler-Toledo Safeline has enhanced profile throat metal detectors and gravity fall systems for manufacturers to experience metal detection as a smoother, safer and less disruptive process.

The Reduced Test (RT) Mode is the first area of improvement, which enables a significant reduction in the frequency of metal detector testing.

Besides testing a metal detector function every two hours, users can extend this to every 12 hours with RT, providing the extended test period is still within the customer’s quarantine period for the product concerned.

On-board technology permanently checks the performance of all critical components within the system, analyzing them 100% of the time to ensure they are in a state of good health.

As the system can track and identify any elements that may lead to a reduction in performance there is no need for such frequent testing throughout production runs.

RT will identify any issues that could potentially affect the performance of the metal detector including operator involvement and alert users before the system goes out of specification.

In order to reduce that five-minute testing window, the automatic test system was developed to keep downtime to a minimum.

ATS automatically introduces three test pieces into the metal detector’s aperture in a controlled manner via a pneumatic system – one ferrous, one non-ferrous and one stainless steel – at the touch of a button.

A four-test sample option is also available, to facilitate testing for aluminum.

In terms of performance, new eDrive technology drives greater power to the transmit coil of the metal detector, enabling it to detect significantly smaller real life metal contaminants.

Fitted with eDrive, Mettler-Toledo’s latest throat metal detectors and gravity fall systems deliver up to 20% increased spherical sensitivity.

This translates into significantly improved wire length detection capabilities, for enhanced product quality, increased consumer satisfaction and greater brand protection.

The fourth element is called Emulation.

Using VNC technology, Emulation allows operators to mirror the human machine interface of one or multiple Profile metal detectors onto remote networked devices, including mobile phones, tablets and laptops.

The user downloads a complimentary application from the app store and links it directly to the metal detector.

Quality personnel can therefore log in from an office, for example, and remotely monitor the current status of the detector, view any setting changes that have been made, and review access log statistics without having to be directly in front of the metal detector.
