How Detectable Are We

What is the answer to the question:


 "How detectable are Detectamet products?"


Detectamet products are made from various non metallic materials (materials that offer the best capabilities for food applications that cannot always use a metal alternative), most Detectamet products are made with a proportion of a metallic magnetic trace element which is present through out the whole object, this is at a size and concentration that allows a homogeneous flow throughout, ensuring that all parts are potentially detectable.


Other products have a metallic strip etc bound to the product. These products are not detectable throughout.


Detectamet products are all detectable - but there will be a cut off point. This will not be systematic for all customers and indeed for all machines/lines or sites.


There is no 100% guarantee of zero risk with any detectable products.

Even metal - have you ever considered why small pieces of metal are able to get into production lines?


There  will always be a limit as to at what point the Detectamet material (or any detectable material) will stop being detected!

This point will generally be when the metal content in the object is smaller than the settings you are using. At this point any metal foreign object will pass through your system. Metal detection systems are a safeguard to a point.


Metal detection is not a precise science. Machines may be very accurate, high tech and high specification instruments but there are many variable's to consider:

Type of food or product


Speed and orientation of the metal

Detector settings

Sensitivity and age.....

to name the most common ones!


Contrary to the rule - many  Detectamet products will be detected in general better within a wet environment rather than dry - but will achieve good results to implement into HACCP for all areas.


Ask yourself these questions:


What do you have the metal detector set at? Which areas have you tested in WET or DRY?

Ferrous ?

Non Ferrous ?

Stainless Steel ?

What was the smallest piece detected?


Lost or found?

Ask yourself this important question : By what percentage am I now safeguarding my customers? - If you have a non metal detectable pen you have 100% chance of facing an issue caused by the potential of a LOST pen. If you have a Detectamet pen which can detect to a piece as small as 5mm then you have a 95% chance that lost pen will be FOUND.

Remember that Detectamet products show that you are using all due diligence, and you have taken the best precautions available.


We strongly advise that you always carry out in house tests on all the Detectamet products. For more help and information please contact our Technical Sales at for more information/test results achieved by Detectamet, Data Sheets etc.

Many people think of magnetism as a property of metal, particularly iron, since common household magnets are made from iron. Electrical currents are actually the force behind magnetic fields, which form as electrical charges move around. On a large scale like an electromagnet, the magnetic field is created by passing current through wires. In the case of a household magnet, the field is created by the movements of electrons in their electronic orbits.

An electromagnet works on the principle that an electric current not only allows electrons to flow in a circuit, but also generates a small magnetic field. When a wire carrying electricity is coiled, the magnetic field becomes even stronger. Iron or steel objects surrounded by this coiled electric wire also become magnetized. This combination of electronic energy, coiled wiring and conductive metal object forms the basis of an electromagnet.


The science behind Metal Detection was first discovered over 100 years ago and was published by James Clerk Maxwell.


Maxwell was a theoretical physicist, he explored theories on how the natural world works using mathematical equations. In 1873 he published a set of equations that described how electricity and magnetism are the same thing.

15 years later it was proved in an experiment that his theory was correct.

This was carried out by Heinrich Hertz.


Today we still use the term "Hertz" to describe the frequency, or speed, at which an electromagnetic wave is generated.


The discovery by Maxwell means that light, radio waves, magnetic waves, microwaves, X rays and many other forms of energy can be created with the use of electricity.


It is this scientific understanding of the nature of electricity and magnetism which has allowed us to build all sorts of detectors.
