Metal Detector Weeds Out False Rejects

Mettler-Toledo's Profile Advantage metal detector is said to produce up to 95% less false rejects by combining Multi-Simultaneous Frequency (MSF) and Product Signal Suppression technology.

Using a sophisticated inspection algorithm, the metal detector all but removes product effect from the process. The result is up to 50% improvements in spherical sensitivity levels, compared to conventional metal detectors, enabling significantly smaller metal contaminants to be detected in products that are wet, hot, chilled, cooling or packaged in metallized film.

 

Central to the Multi Simultaneous Frequency (MSF) technology of the Profile Advantage is the '3S' algorithm and its Product Signal Suppression feature. Unlike metal detectors that capture and store the active product signal, the Profile Advantage modifies the signal during setup so that the food product presents itself as if it were a dry product without product effect.

 

Traditionally the solution to this problem has been to set the sensitivity of the metal detector lower to eliminate false rejects, thereby limiting its ability to detect all contaminants. By suppressing those false signals, the Profile Advantage inspects products at full sensitivity, ensuring more effective inspection and maximizing product safety. Meat and poultry producers, for example, typically see false reject rates associated with product effect reduced by up to ninety five per cent when trying to detect the smallest metal contaminants.

 

The Product Signal Suppression feature is not only able to cope with challenging applications of wet, moist, high salt content products or those that are in a state of flux cooling or thawing, but also with products packaged in metallized film. This packaging type has traditionally made it more difficult for detectors to compete with other types of technology on performance. However, with MSF technology, the Profile Advantage can meet or exceed factory inspection standards on all metal types and delivers considerably higher performance when detecting aluminium contaminants.

 

In addition to enhanced sensitivity, the metal detector also comes with built-in Condition Monitoring as standard. By continually analyzing the detector's performance, Condition Monitoring provides advance warning of potential problems, enabling maintenance to take place during scheduled downtime, maximizing productivity and uptime. On-board OEE reporting is also included with every Profile Advantage metal detector. More information is available on the Profile Advantage product page.
