A89WS-MK1: weather station Mounting kit
Kit contains: Tripod, Mast, and Arm.
Location
: Before installing the weather station, a suitable location for the sensors must be selected. Ensure that the
weather station is located in as open and unobstructed area as possible such as a rooftop location or a parking lot shade
structure. Use extreme care to prevent contact with electrical power lines while installing the weather station.
•
The pyranometer measures solar radiation. The main concern during installation is an unobstructed view of the sky,
clear of all walls, trees, or other objects which might cast a shadow over the sensor.
•
The wind speed and direction sensor must be installed in a location away from walls or other objects that can
obstruct the flow of the wind. Vertically position the sensor twice the height above adjacent obstructions, and
horizontally position the sensor away from adjacent obstructions six times times the height of the obstruction. For
best performance, position the wind sensor approximately 33 feet (10 meters) above the highest obstacle within a
990 foot (300 meter) radius of the mounting location.
•
It is critical to avoid placing the weather station near HVAC units, or exhaust systems from other mechanical
equipment to avoid interference with the sensors.
Tripod
: Remove the tripod from the packaging. Expand the tripod legs until
the legs are fully extended.
Mast
: Install the mast in the hole in the center of the tripod, and secure using
the bolts in the tripod collars. Tighten the bolt into the mast, and the secure
the bolt by tightening the lock nut against the collar. The nut and bolt require
a ½” wrench.
Arm
: The arm of the weather station
should be positioned on the mast about 8”
from the top, and pointing towards the
equator to prevent the mast from casting a
shadow on the pyranometer.
Use the two u-bolts provided to attach the
arm to the mast. Place the u-bolt around
the back of the mast, then add the metal
adapter bracket. Next, pass the bolts
through the back of the arm. Add the lock
washer and nut on the inside of the arm.
The mast and tripod should be electrically grounded to minimize the probability of any lightning damage.
