METAL DETECTOR
SCOPE
The DET metal detectors can be used
on any conveyor belt, regardless of the
layer height and bulk product handled.
They detect the presence of ferrous
and non-ferrous metals (sphere
25 mm).
They are recommended for :
– the protection of an installation
against metal elements ;
– the control of pureness.
TECHNICAL DESCRIPTION
The DETs generate a pulsating primary
magnetic field by the emitting coils.
The induced eddy currents are permanently
controlled by the receiving coils.
When this field is altered, it indicates
the presence of a ferrous or non-ferrous
metal element, regardless of the
handled product's characteristics
(moisture content, granular size,
magnetism, density).
They consist of the following
components :
– a frame, made of a resistant and nonconductor
composite ;
– coils resistant to shocks and
impacts. The receiving coils are
doubled to compensate for electromagnetic
interferences (electric
motors, radio transmitters, etc.) ;
– a generator ;
– an ORETRONIC control and calculation
unit, built around a high-capacity
microprocessor, installed in sealed
case (IP55) with ergonomically
designed display.
INSTALLATION MODALITIES
The DETs are installed on the conveyor
belt's structure without requiring
any changes or actions on the conveyor
belt. After installation, the
ORETRONIC unit is calibrated.
SPÉCIFICATIONS
Performances vary according to various
parameters :
– characteristics of the products to be
handled ;
– characteristics of the metal elements
to be detected ;
– conveyor belt speed.
10 DET models are offered according
to the conveyor belt standard :
400, 500, 650, 800, 1000, 1200,
1400, 1600, 1800, 2000 mm.
ADDED FEATURES
The DET incorporated microprocessor
allows programming the DET for a specific
selected usage :
– automatic static calibration ;
– adjustable selection ;
– positive detection, independently
from the conveyor belt load or the
type of products ;
– digital signal processing ;
– continuous automatic zero ;
– retrieval when passing over staples
and other listed magnetic elements ;
– swiveling upper coil protected
against shocks ;
– mounting without removal of
conveyor belt ;
– anticorrosion and non-magnetic
support frame
USAGE MODE
No required servicing or maintenance
of the magnetic part.
Coils must be periodically checked for
cleanliness.
