Deployment Guidelines
•
The sensor can be damaged with improper handling. Store it in the shipping box until you are ready to install it.
•
To ensure correct orientation of the wind vane, the smart sensor must be mounted so that the anemometer arm points north. See
the logger manual at www.onsetcomp.com/support/manuals/s-wcf for instructions for accurately aligning the sensor to true north.
•
For the most accurate readings, the smart sensor should be mounted 2 m (7 ft) or more above the ground and consistent with
meteorological standards for the application. The smart sensor should be mounted at least 2.1 m (7 ft) above the roof line if
mounted on a roof and mounted at a distance of at least five times the height of the nearest tree, building, or other obstruction. You
may do this by mounting the smart sensor on an Onset tripod or mast, or a metal pipe. You may mount the smart sensor on a
wooden post if it has a side facing due north for mounting (refer to the logger manual for instructions on mounting on a wooden
post at www.onsetcomp.com/support/manuals/s-wcf).
•
The sensor should be mounted vertically in a location free of wind shadows.
•
For accurate wind speed measurements, mount the sensor at a distance of at least five times the height of the nearest tree, building,
or other obstruction.
•
Secure the sensor cable with cable ties to protect it from damage.
•
The tripod or mounting mast must be properly grounded. Use the grounding kit (M-GKA).
•
If you live in an area subject to frequent thunderstorms, installing a lightning rod nearby can
reduce the risk of damage.
•
Use the guy wire kit (M-GWA) to secure the mast where the wind sensor is mounted so that it
does not vibrate.
•
To minimize measurement errors due to ambient RF, keep the probe cable as far as possible
from other cables carrying high frequency or high-current signals.
•
To provide long-term protection from moisture entry, the smart sensor adapter must be
mounted horizontally and with the cable wires routed with drip loops so that water drains away
from the cable entry point as shown in the example at right. When mounted properly, the
housing is weatherproof (but not waterproof).
