In this case, the system is designed to detect both ferrous metals (which contain iron) and non-ferrous metals (such as aluminum, copper, and other metals that do not contain iron). This makes it suitable for detecting any type of metal that may be present in the bag.
The detection system typically consists of a metal detector sensor that is placed under a conveyor belt or other material handling system. As the bag passes over the sensor, the electromagnetic field interacts with any metal present in the bag, causing the sensor to detect the metal.
If the system detects metal in the bag, it will trigger an alarm or other alert to notify operators of the issue. This can help to prevent contamination of products being packaged in the bags, as well as ensuring that bags are not mistakenly shipped with metal objects inside.
