Wind Monitors
1. General Description
The 05103, 05106, and 05305 Wind Monitor sensors are used to measure
horizontal wind speed and direction. The 05305 is a high performance version
of the 05103 designed to meet PSD specifications for air quality applications.
The 05106 is recommended for marine applications.
Wind speed is measured with a helicoid-shaped, four-blade propeller. Rotation
of the propeller produces an AC sine wave signal with frequency proportional
to wind speed.
Vane position is transmitted by a 10K ohm potentiometer. With a precision
excitation voltage applied, the output voltage is proportional to wind direction.
The R.M. Young Instruction Manual includes additional information on the
operating principles, installation and maintenance of the sensor.
Lead length for the Wind Monitor is specified when the sensor is ordered.
Table 1-1 gives the recommended lead length for mounting the sensor at the
top of the tripod/tower with a 019ALU or CM200 series crossarm.

The black outer jacket of the cable is Santoprene® rubber. This
compound was chosen for its resistance to temperature extremes,
moisture, and UV degradation. However, this jacket will
support combustion in air. It is rated as slow burning when
tested according to U.L. 94 H.B. and will pass FMVSS302.
Local fire codes may preclude its use inside buildings.
NOTE
3. Installation
3.1 Siting
Locate wind sensors away from obstructions (e.g. trees and building). As a
general rule of thumb there should be a horizontal distance of at least ten times
the height of the obstruction between the windset and the obstruction. If it is
necessary to mount the sensors on the roof of a building, the height of the
sensors above the roof, should be at least 1.5 times the height of the building.
See Section 9 for a list of references that discuss siting wind speed and
direction sensors.
3.2 Assembly and Mounting
Tools Required:
•5/64” Allen wrench
•1/2” open end wrench
•compass and declination angle for the site (see Appendix A)
•small screw driver provided with datalogger
•UV resistant cable ties
•small pair of diagonal-cutting pliers
•6 - 10” torpedo level
Install the propeller to the propeller shaft using the nut provided with the
sensor.
The 05103 mounts to a standard 1” IPS schedule 40 pipe (1.31” O.D.). A 12”
long mounting pipe ships with the 03001 for attaching the sensor to a 019ALU
(Figure 3-1), or CM200 series crossarm with the CM220 or PN 1049 (Figures
3-2 and 3-3). The 05103 can also be mounted to a CM110 series tripod mast
with the CM216 Mast Mounting Kit.
Mount the 019ALU or CM200 series crossarm to the tripod or tower. Orient
the crossarm North-South, with the 1” Nu-Rail or CM220 on the North end.
Appendix A contains detailed information on determining true north using a
compass and the magnetic declination for the site.
Secure the mounting pipe to the 019ALU or CM220. Place the orientation
ring, followed by the 05103 on the mounting pipe. Orient the junction box to
the south, and tighten the band clamps on the orientation ring and mounting
post. Final sensor orientation is done after the datalogger has been
programmed to measure wind direction as described in Appendix A.
Route the sensor cable along the underside of the crossarm to the tower/tripod
mast, and to the instrument enclosure. Secure the sensor cable to the crossarm
and mast using cable ties.

5. Example Programs
This section is for users who write their own programs. A datalogger program
to measure this sensor can be created using Campbell Scientific’s Short Cut
Program Builder software. You do not need to read this section to use Short
Cut.
5.1 Wind Speed
Wind speed is measured with the Pulse Count instruction, and with the low
level AC configuration. For dataloggers programmed with Edlog, specify
configuration code 21 to output frequency in Hertz.
The expression for wind speed (U) is:
U = MX + B
where
M = multiplier
X = number of pulses per second (Hertz)
B = offset
Table 5-1 lists the multipliers to obtain miles/hour or meters/second when the
Pulse Count instruction is configured to output Hz (configuration code 21).
The helicoid propeller has a calibration that passes through zero, so the offset
is zero (Gill, 1973; Baynton, 1976).
TABLE 5-1. Wind Speed Multiplier
(With Configuration Code 21*)
Model Miles/Hour Output Meters/Second Output
05103 or 05106 0.2192 0.0980
05305 0.2290 0.1024
*When configuration code 11 is used, the multiplier above is
divided by the execution interval in seconds.
5.2 Wind Direction
The wind vane is coupled to a 10K potentiometer, which has a 5 degree
electrical dead band between 355 and 360 degrees.
The EX-DEL_SE measurement instruction is used for dataloggers that are
programmed with Edlog (e.g. CR10X, CR23X) and the CR200. The
measurement result is mV; the multiplier to convert mV to degrees is
355deg/excitation mV.
The BRHalf measurement instruction is used for dataloggers that are
programmed with CRBasic (e.g. CR1000, CR3000). The multiplier to convert
the measurement result (mV/excitation mV) to degrees is 355.

05103, 05106, and 05305 R.M. Young Wind Monitors
The excitation voltage, range codes, and multipliers for the different datalogger
types are listed in Table 5-2. Appendix B has additional information on the P4
and BRHalf measurement instructions.

5.3 Wind Vector Processing Instruction
The Wind Vector output instruction is used to process and store mean wind
speed, unit vector mean wind direction, and Standard Deviation of the wind
direction (optional) using the measured wind speed and direction samples.
5.4 Example Programs
The following programs measure the Wind Monitor 05103 every 5 seconds,
and store mean wind speed, unit vector mean direction, and standard deviation
of the direction every 60 minutes. Wiring for the examples is given in Table
5-3.

5.5 Long Lead Lengths
When sensor lead length exceeds 100 feet, the settling time allowed for the
measurement of the vane should be increased to 20 milliseconds.
For dataloggers programmed with Edlog (and the CR200), the EX-DEL-SE
(P4) measurement instruction should be used. Enter a 2 in the P4 “Delay”
parameter for a 20 millisecond delay.
9

05103, 05106, and 05305 R.M. Young Wind Monitors
For dataloggers programmed with CRBasic, increase the “Settling Time”
parameter of the BRHalf instruction to 20 milliseconds (20,000 microseconds).
The 60 Hz rejection option can not be used with the DC
Half Bridge instruction, when the delay is not zero. Do not
use long lead lengths in electrically noisy environments.
CAUTION
6. Sensor Maintenance
Every month do a visual/audio inspection of the anemometer at low wind
speeds. Verify that the propeller and wind vane bearing rotate freely. Inspect
the sensor for physical damage.
Replace the anemometer bearings when they become noisy, or the wind speed
threshold increases above an acceptable level. The condition of the bearings
can be checked with a paper clip as described in the R.M. Young manual.
The potentiometer has a life expectancy of fifty million revolutions. As it
becomes worn, the element can produce noisy signals or become non-linear.
Replace the potentiometer when the noise or non-linearity becomes
unacceptable.
Contact Campbell Scientific for a Return Materials Authorization (RMA)
number at [phone].
7. Troubleshooting
7.1 Wind Direction
Symptom: -9999 or no change in direction
1. Check that the sensor is wired to the Excitation and Single-Ended channel
specified by the measurement instruction.
2. Verify that the excitation voltage and Range code are correct for the
datalogger type.
3. Disconnect the sensor from the datalogger and use an ohm meter to check
the potentiometer. Resistance should be about 10K ohms between the
Blue and White wires. The resistance between either the Blue/Green or
White/Green wires should vary between about 1K to 11K depending on
vane position. Resistance when the vane is in the 5 degree dead band
should be about 1M ohm.
Symptom: Incorrect wind direction
1. Verify that the Excitation voltage, Range code, multiplier and offset
parameters are correct for the datalogger type.
2. Check orientation of sensor as described in Section 3.
10

05103, 05106, and 05305 R.M. Young Wind Monitors
7.2 Wind Speed
Symptom: No wind speed
1. Check that the sensor is wired to the Pulse channel specified by the Pulse
count instruction.
2. Disconnect the sensor from the datalogger and use an ohm meter to check
the coil. The resistance between the red and black wires should be about
2075 ohms. Infinite resistance indicates an open coil; low resistance
indicates a shorted coil.
3. Verify that the Configuration Code, and Multiplier and Offset parameters
for the Pulse Count instruction are correct for the datalogger type.
Symptom: Wind speed does not change
1. For the dataloggers that are programmed with Edlog, the input location
for wind speed is not updated if the datalogger is getting “Program Table
Overruns”. Increase the execution interval (scan rate) to prevent
overruns.

Appendix A. Wind Direction Sensor
Orientation
A.1 Determining True North and Sensor Orientation
Orientation of the wind direction sensor is done after the datalogger has been
programmed, and the location of True North has been determined. True North is
usually found by reading a magnetic compass and applying the correction for
magnetic declination; where magnetic declination is the number of degrees
between True North and Magnetic North. Magnetic declination for a specific site
can be obtained from a USGS map, local airport, or through a computer service
offered by the USGS at www.ngdc.noaa.gov/seg/geomag/. A general map
showing magnetic declination for the contiguous United States is shown in Figure
A-1.
Declination angles east of True North are considered negative, and are subtracted
from 0 degrees to get True North as shown Figure A-2. Declination angles west
of True North are considered positive, and are added to 0 degrees to get True
North as shown in Figure A-3. For example, the declination for Logan, Utah is
14°East. True North is 360°- 14°, or 346°as read on a compass.
Orientation is most easily done with two people, one to aim and adjust the
sensor, while the other observes the wind direction displayed by the
datalogger.
1. Establish a reference point on the horizon for True North.
2. Sighting down the instrument center line, aim the nose cone, or
counterweight at True North. Display the input location or variable for wind
direction using a hand-held keyboard display, PC, or palm.
3. Loosen the u-bolt on the CM220 or the set screws on the Nu-Rail that secure
the base of the sensor to the crossarm. While holding the vane position,
slowly rotate the sensor base until the datalogger indicates 0 degrees.
Tighten the set screws.
