Metal Detector
AD-4976

AD-4976 Series:
Technology that Aids in Manufacture ofTop-Quality Products
Detection and removal of contaminants
during production/processing of food,
pharmaceuticals, chemical products andclothing is a particularly important themein terms of compliance with productliability laws and the HACCP system.

A sensor head of an electromagnetic induction type metal detector consists of a transmitter coil and two receiver coils thatare equally spaced and are differentially connected.
Basicprinciple ofA magnetic field is generated inside the coils and the productmetal detection
to be inspected passes between the coils. When no contaminants exist, both receiver coils receive an equal amount ofmagnetic flux. When a product contaminated with an electrically conductive item (such as metal) passes through the coils,
the magnetic flux balance is disturbed and creates a differential output signal.
Metal detectors detect metal contaminants by processing this differential output signal.

A&D METAL DETECTOR

Advanced Metal Detector by A&D
Multi-frequency
supportAutomatic frequency selection system
Before the start of an inspection, the AD-4976 automatically selects the mostsuitable frequency band for higher sensitivity and more stable inspection byanalyzing the frequencies of the three detection bands. This system realizes astable inspection and better sensitivity.

High/medium/low frequency bands
You can conduct metal detection for dry products, wet products, products inaluminum metalized packages as well as missing product inspection for oxygen
absorbers.
As an option, you can also conduct metal detection for products which containoxygen absorber.

AND-MD-MEET

Visualization of external noises (patent pending)
AND-MD-MEET (AandD Metal Detector Measurement Environment Evaluation Tool)
AND-MD-MEET is the software that measures and displays the electromagnetic
noise of the environment using the sensor head of the metal detector. This software
has been installed into A&D’s metal detector for the first time.
With this function, it is possible to visualize noise conditions (up to the currently
used frequency and surrounding frequencies) in installation environments that weredifficult to understand in the past, enabling you to implement noise countermeasuresmore easily and quickly.

Warm-up Free

Improvement to temperature/phase characteristics enables stable inspection
immediately after startup.

Improvement ofenvironmental
resistance

Effects due to noise such as from an inverter has been mitigated.
Anti-vibration capability has been improved.

Adjustable height ofsensor head

The height of the sensor head from the conveyor is adjustable.
This allows you to position products to pass through closer tothe center of the aperture. This decreases the product effect andleads to more stable use.

Hygiene design

Sensor head is made of stainless steel, making it easier to cleanand gives it a more robust structure.
Dust-/water-proof (IP66) sensor head and conveyor unit reduces
accumulation of dust and dirt.

IP66

Dust-/water-proof (IP66) sensor head and conveyor unit allows
the AD-4976 series to be washed cleanly.

Easy Operation
7” color touchscreen

Intuitive user interface and high visibility LCD color touchscreen with high-speed
CPU enable easier operation.

Product registration
using images imported
from USB flash drive

Product images can be quickly uploaded
to the metal detector from a USB
flash drive. The images can be easily
registered as a thumbnail image foreach product. This makes productidentification when selecting a productfaster and simpler.
Up to 1,000 products can be registeredand categorized into 10 different groups(up to 100 products per a group).

The screen can be shown in English, Spanish, Russian, Korean, Chinese andJapanese languages as standard specification.
Languages can be easily switched just by selecting a button on screen.

Multi-language

Easy MaintenanceDetachable conveyor
unit without tools

The resin plate of the conveyor unit is detachable
without tools.

Easy maintenanceThe conveyor belt is driven by gears, making it
easy to clean, maintain, and replace the belt.
Durability of the conveyor unit (IP66) has been
improved and belt meandering occurs less often.

Remote maintenance

AD-4976’s touchscreen can be operated from a PC via a LAN cable connection
using device operation software for PC. Also, by utilizing remote control software tocontrol another PC, the touchscreen can be operated from another PC.
This is useful for remote maintenance since engineers can check machine settingseven if the AD-4976 is in a remote place.

Easy Data Management
History management

Operation Log and Inspection History can be helpful for HACCP management.

Inspection History & Batch Result
Inspection result per inspection is saved
automatically.
Numbers & ratio of pass/fail products can besummed up automatically.
Graphs of the result can be seen on thetouchscreen.
Inspection results from the start to the end of aninspection can be saved as a Batch Result in PDF format.

Operation Log
A log of setting changes can be saved and displayed, up to the last 100 changes.

User management

Output to a USBflash drive* USB flash drive is not included.

For each user registered, you can limit the operations they can perform dependingon their user level.
Inadvertent operation can be avoided by assigning each user a user level from thefour levels below.

Inspection history (csv), operation log (csv), and batch result (PDF)
can be output to a USB flash drive.
Please start inspection after connecting a USB flash drive to theconnector on the sensor head.

speed can be raised up to a range of 20.0 m/min to 80.0 m/min.
In this case, the conveyor load capacity becomes half of that of normal mode.

Base*2 The conveyor load capacity values are for when the AD-4976 is used in a clean
environment. However, these values will vary depending on the environment
where the AD-4976 is used.
