2. INSTALLATION
2.1 Selecting the installation location
The best location for installation of the units of the S300 Series is in a section
of duct where the particulate has an even distribution and the flow is laminar.
This is to ensure that the sensor rod comes into contact with a representative
flow of particles.
The ideal position would be in a section of duct that has no bends, valves,
dampers or other obstructions for a distance equal to at least three duct
diameters downstream or upstream (preferable 5 x duct diameter).

In some applications, a compromise must be made and the sensor will have to
be fitted in a position that satisfies the majority of above requirements. The
units of the S300 Series must be attached to metal ductwork so that they will
be electrically shielded from interference and be provided with a ground
reference. For non-metal ducts, a section of the duct, approximately five
diameters in length, should be covered with a metal foil or fine-mesh outside of
the duct.
The units must not be installed in direct sunlight or in areas where the ambient
temperature is above 45
