INSTRUCTION
3.1.2.3 Load-bearing
structure
The Customer transport system shall be designed in order to properly position the Probe according
to the required minimum distances from metal structures (fixed and moving) both of the conveyor
itself and of the adjacent systems, in line.
Take into consideration the fact that a conveyor belt mat is subject to metal contamination and must be periodically
disassembled to be cleaned or replaced. Set up the system to facilitate this operation.
During assembly the solidity of the load-bearing structure should be borne in mind, in order to ensure
that the detector does not oscillate, causing false alarms.
The load-bearing structures of the transport system must be stable and not subject to detectable
vibration when the belt is moving.
For a
THS/MN21
the structure of the transport system must be in non-magnetic steel (e.g. AISI 316).
Welded metal structures are recommended.
If some of the frame parts, (i.e. crossbeams
T
) are
screwed, insulate electrically all connections with the
bearing structure, except one, to ensure the
grounding.
Make sure that the metal crossbeams of the frame
are as far as possible from the Probe opening and, in
any case, at no less than the minimum distance
required for fixed metal parts.
Screwed metal contacts can cause intermittent coils that,
according to their position and geometry, can interact with the
electromagnetic field of the Metal Detector causing interference.
