3.1.2.4.3 Side panels to contain the material in transit
In case the product could come in touch with the Probe, during the
transit, it is recommended to use plastic side panels (or insulated)
to avoid it.
The side panels, near the Probe, must be made of insulating
material (plastic, wood, etc.).

One side of the roller must be insulated
from the metal frame of the conveyor belt, to prevent the formation of
electromagnetic coils which might interfere with the operation of the Metal Detector and allow in any way the ground
discharge of any electrostatic charges accumulated by the belt in motion.
It is recommended, where possible, to use plastic rollers or metallic rollers covered by insultaing material, so as to save
the belt from metallic contaminations.
