Technology & Function
Why a Metal Detector?
Raw Material Purity - Incoming Inspection
This measuring principle reacts to electrical conductivity and
magnetism and is therefore able to recognise all types of
metals, i. e. non-ferrous metals and stainless steel. However,
magnetic metals can be recognised slightly better than
nonmagnetic metals. The measuring field penetrates the food
products and recognises metal pieces even deep within the
product or in packages.
Producers who can precisely verify raw materials are able to
reduce non-conformance costs by making early diagnoses
and also to assess their suppliers’ product quality.
Metal Detectors respond to
Electrical Conductivity
Magnetism
Finished Product Purity - Final Inspection
All metals are detected, even non-ferrous and mild steel.
The customer shall receive only pure products with the
maximum purity that can be achieved in the technological
process.
Magnetic metals can be detected better than non-magnetic
metals.
The task of metal detectors is it to detect metallic foreign
bodies in non-metallic products, and they are thus used in
many industrial production processes, particularly in the food
production sector, where great demands are made to product
quality and hygiene.
Protection of Production Facilities - Pr ocess Control
Metal pieces having managed to enter the material stream
can severely disturb or even destroy production facilities.
Down-times of machines and plants can negatively affect the
constancy of product quality and quantity.
HACCP-Critical Check Point for Metallic For eign Bodies
A critical control point is a certain point within the production
chain where lacking supervision can result in a non-acceptable
risk to human health.
Function
The metal detector operates according to an inductive
measuring principle. A high-frequency electromagnetic
alternating field is generated by a transmitter coil. If a metal
piece passes through the metal detector, the field undergoes
a change according to the magnetic and electrical properties
of the metal piece.
The change in the field is measured by a balanced pair of
receiver coils, subsequently reprocessed and digitally
analysed by the control unit.
The measuring field penetrates the food products and
recognises metals objects even inside packages.
Technical limits = Product Effects
The maximum sensitivity is limited by the physical laws on
which the measuring principle is based. Food often has a
more or less strong electrical conductivity due to small
contents of salt, sugar, minerals and water which cause the
metal detectors to respond. This reaction is referred to as
product effect.
In most cases, the sensitivity attainable in practise primarily
depends on the metal detector’s capability to compensate
the product effect.
Technology & Function
Metal Detecting Systems
Test Procedures and Intervals
Conveyors / METAL SHARK® BD
With the help of a metallic test bullet of a defined size, the
function of the metal detector can be tested in operation. A
test bullet is added to the product and subsequently passed
through the metal detector. If the detector recognises the
bullet, the test is successful.
Conveyor: The metal detector is integrated into a belt
conveyor either with the belt passing through the frame search
coil or being installed just below the belt as flat search coil.
There are several devices available to reject the detected metal
pieces (e. g. Pusher).
Metallic test bullet
encapsulated in plastic
Gravitiv Feed / METAL SHARK ® GF
The test intervals shall be short enough: All products having
passed the metal detector since the last test procedure must
be able to be re-tested once again. In addition, tests should
be carried out at the beginning of the shift and when changing
products.
Documentation
Down-pipe applications: Bulk material falls into a pipe through
the metal detector. Metal pieces are rejected by means of a
separation flap.
Companies working in accordance with HACCP and ISO 9000
shall document the metal detection process in writing to make
it traceable, verifiable and safer.
By means of a logging printer connected to the metal detector
by data interface, it is possible to produce complete,
automatic documentation of metal detection, tests and all
set parameters. On request, a suitable printer can be supplied
together with the metal detector.
Inline / METAL SHARK ® IN
Pipeline metal detectors: This in-line system serves to detect
metal pieces in pasty or liquid products, and it is integrated
into the conveyor pipes (e. g. with milk pipe fittings). The metal
pieces can be discharged from the system by means of threeway-special-valves.

HACCP and ISO 9000
What is HACCP?
HACCP (Hazard Analysis and Critical Control Points) is a program to avoid non-conformances in the Food Processing
Industry.
HACCP and Metal Detectors
With respect to metal detection, the HACCP program requires
the following:
Critical Control Point
The metal detector is a critical physical control point of the
danger of metal pollution. If control is not carried out, there is
a risk of health hazard.
GMP - Good Manufacturing Practice
Here, detectability defines the critical limiting value for the
calibration to the smallest recognisable metal bullet. A product
has to be kept free from metal pollution as much as possible
by „Good Manufacturing Practice“ (GMP) and according to
the latest state-of-the-art. With reference to metal detectors,
this means that all metal pieces which a modern metal
detector can reliably detect at optimum installation have to
be removed from the product.
Critical limiting value
Setting of the critical limiting value, however, must in any case
enable the metal detector to operate in a stable and reliable
manner without giving random or false alarms.
Systematically and continuously
It must be guaranteed that all products are systematically
and continuously tested by the metal detector.
Documentation
Complete documentation must be made on both operation
and results of the metal detection.
sensitivity for the current product and site is still optimally
set. This includes, in addition, the training and introduction
of new staff and the metal detector’s integration into quality
management.
DIN ISO 9000 and Metal Detectors
It is advisable to elaborate written detailed job instructions
for the metal detector wherein e. g. the measures to be taken
after metal alarm and testing procedures are laid down.
Uponn request, an example for job instructions can be
obtained from Pulsotronik-SKS CASSEL. Furthermore,
reference is made to all the items specified under HACCP.
Sample: Job instruction according ISO 9000
Job instruction: General Function
Instruction for: Quality management staff, HACCP-Manager.
At job start:
Switch the metal detector on and wait until STATUS OK is
displayed.
Select the appropriate product number (refer to job instruction
„Recall product number“).
Check Metal Detector Function:
Move some metal free product samples through the metal
detector. A metal alarm must NOT occur!
Move another product sample along with a metal test object
through the sensor head.
A metal alarm must occur now!
Correction Procedure
If a metal piece is detected in the production process, it is
absolutely necessary to find its source. The source of metal
contamination has to be rigorously eliminated in order to
exclude further pollution from the same source.
The test intervals must be short enough. All products having
passed the metal detector since the last test procedure must
be able to be re-tested again. In addition, tests should be
carried out at the beginning of the working shift and when
changing products.
Maintenance
Modern metal detectors are equipped with an automatic selfcontrol system and are, therefore, maintenance-free.
Production:
It must be guaranteed that all products are systematically
and continuously tested by the metal detector.
Preventive maintenance by the manufacturer of metal
detectors include consulting the customer and checking the
system in situ for correctness of the equipment after a longer
operation period. It is checked that no external interference
affects the system’s performance and that the detecting
Metal alarm:
If a metal piece is detected in the production process, it is
absolutely necessary find its source. The source of metal
contamination has to be rigorously eliminated in order to
exclude further pollution from the same source.
HACCP and ISO 9000
Example: Daily Metal Detector Record
It is recommended to regularly test the metal detector with
standardised test objects and to keep records of these tests
in a daily metal detector log. Metal testing bullets are generally
supplied along with the detector.
A suitable metal testing object and a testing schedule should
be established for the examination: The testing object should
be a bullet of the smallest diameter which detection is
required. The bullet is passed through the detector along with
the product in order to observe whether a metal detection
signal is generated.
The testing schedule should establish when the detector shall
be tested and by whom. Example: The quality manager on
duty has to test the detector using the testing object one
hour after the start of each shift. The test results including
date, time and signature are recorded in the log. Example:
Test object recognised, 24 August 2001, 08:30, signed, Smith.

METAL SHARK® Control Unit The new generation
in metal detecting technology
Application and Operating Principle
For a number of years, our company has been developing
and producing highly sensitive metal detectors for industrial
purposes.Our development department is utisiling practical
experience from the daily practice. This results in constant
improvement of equipment and production methods. Already
when the company started introducing the digital signal
processing technology, it became a trendsetter for technical
standards.
For permanent industrial operation, both enclosure and control
united are made of sturdy and food-grade high-grade steel.
The unit is service-free.
METAL SHARK® is a new range of products which are
particulary ’agressive’ ,i.e. they are extremly sensitive to any
kind of metallic contamination. That is why METAL SHARK®
systems are preferably used in the foodstoff industry to yield
the most precise metal detection results.
In case that no standard design is available for installation in
a certain production line, the Pulsonic-SKS/Cassel team will
provide a customised solution.
The metal detector can be supplied on a short notice. The
most common sizes and types - including various
accessories, like belt conveyors, pneumatic pushers and
signal transducers - are in stock.
The heart of all METAL SHARK® detectors is the electronic
control unit with its completely new design. For the first time,
all electronic compenents are arranged on a common board,
and almost all functions are digital. Its measurement accuracy
and products effect blankingout enable the METAL SHARK®
detectors to supply optimum results. So it is one of the most
powerful metal detectors available. Owing to series
production, its price, however, remains on the level of
conventional metal detectors.
In practical use, settings of metal detectors often need to be
checked quickly and reliably during running production. That
is why great value was attached to user-friendly operation.
The software is self-explanatory and leads the operator step
by step through the setup menus. A LED bar indicates the
quantity of the product effect and the metal detection
threshold. The unit is operated by means of a foil keyboard at
the outer side of the control cabinet..
The product effect blanking-out of the METAL SHARK®
detectors was refined further. Especially the elecctric
conductivity of salty and wet foodstuffs is influencing the
measurement signals of the metal detector. Only if these
signals are precisly characterised and filtered, even the
smallest metallic particles can be found in such products.
This precision of product effect blanking-out is achieved by
digital sensor processor technology of the latest generation.
The transducer amplification is automatically adapting to the
product. In case that products with both very great and very
low product effects are scanned be one and the same metal
detector, the unit will automatically select the optimum
amplification.

available in standard (short terms of delivery) and customised
equipment. A complete system is ready for operation
immediately after installation.
How to choose the installation place
Both packed and unpacked products can be tested for metal.
As a rule, the smaller the aperture opening of the metal
detector, the better the metal detection performance.
If possible, only packaged goods should be tested, as this
prevents new metal contamination.
If the metal detector is used for machine protection, it should
be installed as near as possible before the machine to be
protected.
METAL SHARK® BD metal detector installation in
existing belt conveyors:
The belt conveyor must have a stable frame support. Supports made of angular metal sheets are not suited for
installation of metal detectors!

How to install the sensor with the assembly frame :
The assembly frame is either directly welded or screwed on
to the support of the customer’s structure. You can choose
the supporting points anywhere on the assembly frame. The
supporting structure should be made of stainless steel and
not be coated in order to ensure good electric conductivity at
the connecting points.
Vibration - When installing the metal detector make sure that
vibrations are reduced to a minimum during operation. Small
vibrations don’t have any influence on the detector’s function.
However, heavy impacts can cause metal alarm.

METAL SHARK GF ® compact for free-falling powder and bulk
products
Low assembly height
Pipe Ø 100-300 mm / 4-12 inch
Food-grade,
stainless design
Typically, the GF compact types are used in gravity feed pipes
and provide high performance in detecting magnetic and
nonmagnetic metals. The bulk material falls through the metal
detector. With the reject flap EX-S, smallest metal objects
are separated from the product stream promptly.
How to choose the installation place in the down pipe:
Install the sensor as high up as possible in the upper area of
the down pipe.
Check: Is the installation height sufficient?
The GF compact types have a low assembly height and are
specially designed for height limited installation points.
However, therefore the metal detecting performance is a little
bit lower compared to the GF types.
Typical products for the METAL SHARK® GF:
Powdered milk
Sugar
Cereals
Proteins
Spices
Granules
The devices are 100% Stainless Steel and are specifically

How to install the sensor with the assembly frame:
The assembly frame is either directly welded or screwed on
to the support of the customer’s structure. You can choose
the supporting points anywhere on the assembly frame. The
supporting structure should be made of stainless steel and
not becoated, in order to ensure good electric conductivity
on the connecting points.
Vibration - When installing the metal detector make sure that
that vibrations are reduced to a minimum during operation.
Small vibrations don’t have any influence on the detector’s
function. However, heavy impacts can cause metal alarm.

Metal detection in sausage production
Even in production lines that meet highest quality
requirements dangerous metal parts get into the raw sausage mass again and again without being noticed. The metal
comes, for example, from broken cutter knifes , shavings from
aluminium clips, or is in the raw meat already on delivery.
The METAL SHARK® IN metal detectors are integrated into
pipelines between sausage stuffer and clip machine. A special
reject valve installed behind the metal detector sorts out the
metal objects together with small amounts of meat mass. A
cutter trolley is placed under the reject valve and collects the
contaminated mass.
The metal detector has an intelligent sensitivity control and
fully automatic product effect blanking-out. That is why
modification of the metal detector settings are not needed
when changing the products, and the device adjusts
automatically for the new product.
According to HACCP, the metal detector is a critical control
point and therefore, it must be checked regularly. A special
inspection hole in the pipeline allows to test the detector
function regularly and easily. To this aim a flexible test stick
with small metal balls is pushed through the pipe.
For daily cleaning, the hygienic structure can be easily
dismantled.
