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
Packaging
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

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.
