2.0 Introduction & Specifications 2.1 Introduction The Wind
Mark III Wind Sensor is a rugged and accurate system for measuring
the speed and direction of the wind. Wind speed is measured by a
3-cup anemometer coupled to a light chopper which converts the
speed of rotation of the cups to a frequency proportional to the
wind speed. Wind direction is measured by a wind vane coupled to a
precision low-torque potentiometer. The wiper voltage of the
potentiometer is a measure of wind direction. 2.2 Specifications
WM-III WIND SPEED Accuracy: 0.25 mph (± 0.11 m/s) or ± 1.5%,
whichever is greater Threshold:

3.0 Installation NOTE: MAKE ALL CONNECTIONS WITH THE POWER OFF.
Carefully unpack the wind set and place the wind speed and
direction sensor (one unit) on a flat surface. Connect the sensor
mating connector end of the cable to the sensor and the opposite
end of the cable to your power source and data recording and/or
display device. Note: The sensor power supply should be a well
regulated voltage ranging from 5 – 15 Vdc. However, in power
sensitive applications (E.g. solar powered systems) we recommend
that the supply voltage does not exceed 7.0 Vdc, this will limit
the sensor total current flow to less than 5 mA. The data recording
and/or display device may be housed in a mainframe or environmental
enclosure, depending on your system application. Some systems
require making individual connections on the datalogger end of the
cable. In these cases, refer to the data logger manual or system
wiring diagram for proper connections. After making and checking
all connections, apply power. The wind speed sensor is located at
the end of the crossarm with the connector, and the wind direction
sensor at the opposite end. Rapidly spin the wind speed shaft and
note that the datalogger or display output increases. Slowly rotate
the wind direction shaft and note that the wind direction output
changes. The wind direction has been aligned at the factory:
however, it should be checked at this time using the alignment
procedure below.

3.1 Wind Vane Alignment Procedure Align the sensor as in the
figure below. The flat on the wind direction cap should be as
indicated. Place the vane on the shaft and align the flats so they
are parallel. A small coin placed against the flats will insure
proper orientation of the vane on the sensor (see figure below).
Tighten the set screws in the vane hub. With the vane as shown in
the figure below, the wind direction output should indicate 90°.
Place the cup set on the wind speed sensor and tighten the set
screws.
FLAT WEST EAST W.S. SENSOR W.D. SENSOR Turn the power off and
remove the connector from the sensors. 3.2 Sensor Orientation The
WM-III wind speed and direction sensor mounts on any ¾ inch IPS
(1.05 inch OD) vertical pipe stub. The sensors should be located
far enough from any obstruction so the actual local wind conditions
are measured, not the turbulent wind conditions caused by some
nearby structure. The World Meteorological Organization recommends
that wind sensors should be located a minimum of 10 meters above
the ground, and a minimum distance of ten times the height of any
neighboring obstruction away from that obstruction. The datalogger
or display device can be located up to 500 feet from the sensors.
In order to obtain accurate wind direction readings, it is
necessary that the sensor be oriented with relation to true north.
The crossarm provides a long axis with which to align the wind
direction sensor. As long as the crossarm pipe is aligned in a true
east-west plane, the wind direction sensor will automatically be
aligned. To find the correct true north orientation of a site, one
must first find the magnetic angle of declination. Several sources
contain this information, such as topographic or aeronautical
navigation maps of the area. For example, Bohemia, New York, which
is located on the eastern coast of the United States, has a
-
Page 9 ISO 9001:2000 Certified
magnetic angle of declination of approximately 13 degrees west.
This indicates the magnetic north is 13 degrees west of true north.
In this case, 13 degrees would be added to 360 degrees. Moving to
the west coast, Seattle, Washington has a declination of
approximately 22 degrees east. This indicates the magnetic north is
22 degrees east of true north. For this reading, 22 degrees should
be subtracted from 360 degrees. A compass sighting perpendicular to
the crossarm in Seattle should read 338 degrees for true east-west
orientation. When a crossarm has been properly aligned, the wind
speed sensor should be oriented west while the wind direction
sensor should be facing east. 3.3 Sensor Installation Install the
cable in its final location and wire the recording/display device
as before. Slide the orientation collar (pin up) over the ¾ inch
mounting pipe and loosely tighten one set screw. Mount the sensor
on the ¾ inch pipe and rotate it until the wind speed sensor points
toward the orientation you have selected. Tighten the set screws in
the sensor mount and connect the cable. Loosen the orientation
collar and slide it up so the pin in the collar is in the slot on
the sensor mount. Tighten set screws in the orientation collar. If
the sensor is removed for maintenance, simply loosen the set screws
holding the sensor onto the pipe and remove it leaving the
orientation collar installed. When replacing the sensor, make sure
the pin on the collar slides into the slot on the sensor mount and
the sensor will be aligned as originally installed. Slot Pin After
a sensor has been installed, it is wise to rotate the wind
direction vane in 45 degree increments starting at 90 degrees and
moving in a clockwise direction while checking the corresponding
data output on the particular data collection equipment being used.
This insures that the entire wind direction system is installed and
working properly. The sensor is now ready for use.

Maintenance 5.1 Wind Speed Transmitter Bearing Replacement Should
it become necessary to replace the bearings, proceed as follows.
Both bearings should be replaced if replacement is necessary.
Drawing Number 102083 will help procedure through before starting.
1. Remove the cups by loosening the two set screws that hold them
to the shaft and lifting the cups off the shaft. 2. Remove the wind
direction cover (item 28). Loosen the two set screws holding the
wind direction transmitter to the crossarm and remove the wind
direction transmitter from the crossarm by pulling on it with a
slow twisting motion. 3. Disconnect the wind direction
potentiometer connector. Loosen the set screws holding the wind
speed transmitter to the crossarm and remove the wind speed
transmitter in the same manner as the wind direction transmitter.
4. Remove the nylon cable ties that restrain the cable service loop
to the board. Remove the two screws holding the printed circuit
board and remove the P.C. Board from the transmitter being careful
not to damage the shutter or light chopper assembly. 5. Remove the
four screws holding the connector to the wind speed transmitter and
pull the connector through the access hole a short distance. 6.
Remove the retaining ring from the shaft with retainer ring pliers
or a small pen knife. If the retaining ring is bent, it must be
replaced.

7. Allow the shaft to slide out through the open end of the
column being careful not to damage the shutter. In some cases, the
wires will impede removal. In this case, carefully remove the
shutter from the shaft. 8. Remove and discard the old bearings. It
may be necessary to push the bearing out from the bottom of the
seats with a long thin rod or the shaft assembly. Pushing lightly
all around the bearing is better than too much pressure on one side
of the bearing. 9. Replace the spacer that was closest to the
shutter on the shaft. 10. Place a new bearing on the shaft and
guide the shaft back in to its hole from the bottom until the
bearing is seated. When the bearing is seated, the retainer ring
groove will be visible at the top of the transmitter. If the
shutter was removed in Step 7 above, replace it at this time. 11.
Hold the shaft in place from the bottom, being careful not to
damage the shutter, place the new bearing over the top of the shaft
and press it down into its seat. 12. Replace the spacers on top of
the bearing and then replace the retainer ring. 13. Reassemble the
crossarm, transmitter assembly by reversing steps 1 through 5.
NOTE: If the shaft assembly is to be replaced, the procedure is the
same as outlined above. 5.2 Wind Direction Transmitter Bearing
Replacement Should it become necessary to replace the bearing,
proceed as follows. Drawing number 102083 will help in locating the
parts described below. Read the whole procedure through before
starting. 1. Remove the cups and vane by loosening the two set
screws that hold them to the shaft and lifting them off the shaft.
2. Remove the wind direction cover (item 28).

3. Remove the cap on the top of the wind direction transmitter.
4. Try lifting the bearing off the shaft. If the bearing is frozen
into the column, unscrew the stainless steel nut at the base of the
column taking care not to let the pot terminals get crushed. Once
removed, slide a thin object down the column and gently tap the
bearing out. 5. Replace the bearing at the top of the column and
reassemble the transmitter. NOTE: Once the cap on the wind
direction sensor has been removed it will be necessary to realign
the cap with reference to the crossarm. Follow the procedure
outlined below: 1. Plug the sensor cable into the crossarm and turn
the unit on. Temporarily tighten one of the set screws on the wind
direction cap. 2. Place the wind vane onto the shaft (do not
tighten the set screws) and align the vane along the crossarm. (See
diagram in Section 2, Installation.) 3. Holding the vane still,
slowly turn the wind direction cap until a reading of 90° is
obtained and tighten the set screws on the vane hub. 4. Loosen the
set screws in the wind direction cap and rotate it until the flats
of the vane and the cap are aligned. Retighten the set screws on
the cap. The wind direction sensor transducer and vane are now
realigned.
