Mettler-Toledo Profile metal detectors

Mettler-Toledo Safeline Limited has launched a series of enhanced features for profile throat metal detectors and gravity fall systems. The four enhancements are aimed at making metal detection a smoother, safer, less disruptive process that adds to the profitability of operations.

Reduced test (RT) mode enables a significant reduction in the frequency of metal detector testing. For example, a customer who was testing metal detector function every two hours 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. Onboard technology permanently checks the performance of all critical components within the system, analysing them 100% of the time to ensure they are in a state of good health.

In order to reduce that 5 min testing window, the Automatic Test System (ATS) was developed. 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 4-test sample option is also available, to facilitate testing for aluminium. The whole process now takes less than 30 s.

For increased performance, eDrive technology drives greater power to the transmit coil of the metal detector, enabling it to detect smaller real-life metal contaminants.

The fourth element is Emulation. Using VNC technology, Emulation allows operators to mirror the HMI of one or multiple Profile metal detectors onto remote networked devices, including mobile phones, tablets and laptops.
