In some applications a compromise has to be made and the sensor will have to be fitted in a position that
satisfies the majority of above requirements.
The Dusty must be attached to metal ductwork so that they will be electrically shielded from interference and
be provided with a grood grounding. For non-metal ducts, a section of the duct, approximately five diameters
in length, should be covered with a metal foil or fine-mesh on the periphery of the duct.
1. The unit shall be installed in a position, where the gas flow passes the sensor rod in a 90° angle.
2. In round cross-section ducts the unit can be installed in any position above the horizontal axis
(between 9 and 3 o’clock). (See figure 2a)
3. For square cross-section ducts, the unit must be positioned in the middle of the top or in the middle of
one of the sides. (See figure 2b)
4. Although the sensor is not affected by vibration, very high vibration levels should be avoided.
5. The units must not be installed in direct sunlight or in areas where the ambient temperature
is above 55
o
C.
6. The sensor rod must not contact the opposite duct wall or any other obstacle inside the duct!
In cases of need the sensor rod can be shorten to a minimum length of 70 mm.
