5.5. Correct positioning of the device
Two rules are essential for optimizing radio ranges
•
The first is to position your product as high as possible.
•
The second is to limit the number of obstacles to avoid excessive attenuation of the radio wave.
Position: if possible, install the transmitter at a minimum height of 1m50 and not glued to the wall
Obstacles: ideally the product should be offset 20 cm from an obstacle, and if possible near an opening (the closer the obs-
tacle is, the more power emitted will be absorbed). All materials encountered by a radio wave will attenuate it. Remember
that metal (metal cabinet, beams...) and concrete (reinforced concrete, partitions, walls...) are the most critical materials for
the propagation of radio waves.
5.6. Installation on a ventilation system
Since Air Handling Unit (AHU) are usually in enclosed areas or on roofs (Rooftop package unit), certain installation rules must be followed to
ensure proper operation of the product:
•
Do not position the product in a location where it will be subject to temperatures outside the product's operating temperature range.
•
Do not position the product directly next to the ventilation system (about 20 cm laterally or the antenna above the box) as these are mainly
made of metal, which may greatly reduce the range of radio waves and therefore the transmission and reception quality of the product.
•
Avoid the use of tubes longer than 2 meters as this may impact the measurements made (longer pressure times).
•
Position the product higher than the box to be monitored so that the cables are always below the product and thus prevent any condensa-
tion (due to humidity) from entering the product and damaging it.
•
Take care when installing the tubes so that they are not pinched or pierced as this will impact the measurements made.
