Position of the conveyor belt inside the probe
• The conveyor belt must pass as close as possible to the lower surface of
the tunnel. In order to prevent it from accidentally rubbing against the
probe it is advisable that it be supported within the probe by means of a
sheet of insulating material
, which is thick enough to support the weight
of the material being transported (approximately 5-20 mm). It is necessary
to take this measure when the belt is of considerable length and must
therefore be supported, while at the same time prevented from vibrating.
The sheet must not touch the probe
(in the illustration an intervening
distance of 5-10 mm is shown); if it were to touch the probe it could send
vibrations to the antenna. In any event, if there is a supporting metal layer
for the belt, when it arrives at the probe, it must be interrupted for a
distance D, to both sides of the antenna.

N.B.: THS/M Model: if the product is contained in an aluminium tray, the
optimum distance between the bottom of the tray and the surface of the
tunnel is 20-30mm.
N.B.: In the standard structure, the conveyor belt passes through the probe in
both directions to avoid having to cut and rejoin it if the probe is replaced. If
necessary, carry out the join as described in the “Maintenance” section.

Side panels to contain the material in transit
• Near the probe, such edges must be made of insulating material (plastic,
wood, etc.).

Inserting the conveyor belt on the THS/A model
The THS/A model allows the installation of one side of
the conveyor belt through the probe, without cutting
the belt itself. The probe has a short section on its
side which can be removed to insert the belt.
Procedure
• Remove screws S.
• Remove section A.
• Move the belt into the probe, or the probe over
the belt, depending on the requirements of the
structure.
• Fix section A in place again using screws S.
