Spymet tracks up to 20 metal pieces simultaneously

An Eriez Magnetics Europe product story
Edited by the Engineeringtalk editorial team Aug 7, 2009

The Spymet metal locator from Eriez Magnetics Europe is an accessory to a metal detector system and is used to track and locate tramp metal on a conveyor belt.

The Spymet has two modes of operation - manual or automatic.

It can track the multiple positions and quantities of metal contaminants on a variable speed conveyor belt, which gives it an advantage over conventional rejection/marking devices that rely on the belt speed to be constant.

Spymet can be operated in conjunction with any metal detector and can be used to operate a third-party device such as a reject arm, inkjet marker or air-blast system.

The accuracy of the system is plus or minus half the metal detector sensor depth and can track up to 20 separate metal pieces simultaneously.

The company claimed the manual mode is useful for applications where the belt is not able to stop immediately (due to a large volume or high speed) after tramp metal has been detected.

The conveyor is divided into 1m-wide zones, downstream from the metal detector sensor.

Once the belt has stopped, Spymet will indicate the zone number and the number of metal contaminates within the zone.

This enables downtime to be reduced, improving productivity and preventing the operator from missing any metal.

Eriez Magnetics Europe said the automatic mode can be used for applications where the conveyor belt does not stop when tramp metal is detected.

Spymet uses large LED modules to enable the operator to see the indication from a distance and is also visible in sunny environments.
