What’s a foreign body inspection system?

A foreign body inspection system is intended to detect foreign bodies contained in articles, which are difficult to find through human eyes.
System Square’s foreign body inspection systems have been used to detect foreign bodies contained in various articles, such as food products, medicines, and resin materials manufactured and processed at factories.
In particular, the requirements for food safety are increasingly becoming severer.
In response to such consumers’ demands, System Square’s foreign body inspection systems help to deliver safe articles to consumers.


Example of foreign body inspection process

As what process a foreign body entered is identified, corrective measures can be taken easily.


Foreign body that can be detected with the metal detector or X-ray inspection system

The metal detector and X-ray inspection system are used for their suitable applications by utilizing their dedicated fields.
To supplement their weak fields, the metal detector and X-ray inspection system may also be used as a set.


What is a metal detector?


The metal detector is utilized in various kinds of
applications, such as food plant.

This metal detector is an inspection machine most widely used as a system that detects a foreign body mixed with products. The metal detector enables non-contact and non-destructive inspection. Furthermore, when the metal detector is combined with the sorting machine, the system automatically rejects faulty products.

About metal detector

A metal detector is intended to find metallic foreign bodies by utilizing the magnetic field. Electric current is flowed through the coil (metallic wire) to produce the magnetic field. As an article to be inspected passes through this magnetic field, the amount of the magnetic field changed by this influence is measured to find an entry of foreign body.

About X-ray inspection system

The X-ray inspection system is so designed that the inside of an article can be seen clearly by utilizing the principles that are basically the same as the X-ray radiography. The X-ray is made to thin beams and these beams are applied to an article to be inspected. The transmit amount is measured with a semi-conductor type line sensor to take photographs as images. Captured monochrome X-ray transmit images are analyzed to automatically distinguish foreign bodies from others. Not only metal foreign bodies, but also stone, glass, bone, and hard rubber foreign bodies can be detected.
