Young Wind Monitors
1. Introduction
The 05103, 05103-45, 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 05103-45 is an alpine version that discourages ice
buildup. The 05106 is recommended for marine applications.
Before installing the Wind Monitor, please study
•Section 2, Cautionary Statements
•Section 3, Initial Inspection
•Section 4, Quickstart
2. Cautionary Statements
•The Wind Monitor is a precision instrument. Please handle it with care.
•If the Wind Monitor is to be installed at heights over 6 feet, be familiar
with tower safety and follow safe tower climbing procedures.
•Danger — Use extreme care when working near overhead electrical wires.
Check for overhead wires before mounting the Wind Monitor or before
raising a tower.
•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.
3. Initial Inspection
•Upon receipt of the Wind Monitor, inspect the packaging and contents for
damage. File damage claims with the shipping company. Immediately
check package contents against the shipping documentation (see Section
3.1, Ships With). Contact Campbell Scientific about any discrepancies.
•The model number and cable length are printed on a label at the
connection end of the cable. Check this information against the shipping
documents to ensure the expected product and cable length are received.

5. Overview
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 10 kΩpotentiometer. With a precision
excitation voltage applied, the output voltage is proportional to wind direction.

7. Installation
7.1 Siting
Locate wind sensors away from obstructions (for example, trees and building).
Generally, there should be a horizontal distance of at least ten times the height
of the obstruction between the windset and the obstruction. If the sensors need
to be mounted on a roof, the height of the sensors above the roof, should be at
least 1.5 times the height of the building. See Section 10, References, for a list
of references that discuss siting wind speed and direction sensors.
7.2 Assembly and Mounting
Tools Required:
•5/64 inch Allen wrench
•1/2 inch 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 inch torpedo level
Install the propeller to its shaft using the nut provided with the sensor.
The Wind Monitor mounts to a standard 1 inch IPS schedule 40 pipe (1.31 inch
O.D.). A 12 inch long mounting pipe ships with the Wind Monitor for
attaching the sensor to a CM200-series crossarm with the CM220 (FIGURE
7-1) or 1049 Nurail® fitting (FIGURE 4-1 in Quickstart section). The 05103
can also be mounted to a CM110 series tripod mast with the CM216 Mast
Mounting Kit (see FIGURE 7-2).
Mount the CM200-series crossarm to the tripod or tower. Orient the crossarm
North-South, with the 1 inch Nurail® 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 Nurail® or CM220. Place the orientation ring,
followed by the Wind Monitor 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.

7.4 Programming
This section is for users who write their own programs. A datalogger program
to measure this sensor can be created using Campbell Scientific’s SCWin Short
Cut Program Generator software. You do not need to read this section to use
Short Cut.
7.4.1 Wind Speed
For CRBasic dataloggers, wind speed is measured using the PulseCount()
instruction. Syntax of the the PulseCount() instruction is:
PulseCount( Dest, Reps, PChan, PConfig, POption, Mult, Offset )
The PConfig parameter should be set to 1 (Low Level AC) and the POption
parameter should be set to 1 (Frequency).
For Edlog dataloggers, wind speed is measured using Edlog instruction Pulse
(P3). The configuration parameter should be set to code 21 (Low Level AC,
Output Hz configuration).
10

05103, 05103-45, 05106, and 05305 R.M. Young Wind Monitors
The expression for wind speed (U) is:
U = Mx + B
where
M = multiplier
x = number of pulses per second (Hertz)
B = offset
TABLE 7-2 lists the multipliers to obtain miles/hour or meters/second when
the measurement instruction is configured to output Hz.
The helicoid propeller has a calibration that passes through zero, so the offset is
zero (Gill, 1973; Baynton, 1976).

05103, 05103-45, or 05106 0.2192 0.0980
05305 0.2290 0.1024
7.4.2 Wind Direction
The wind vane is coupled to a 10 kΩpotentiometer, which has a 5 degree
electrical dead band between 355 and 360 degrees. A 1 MΩresistor between
the signal and ground pulls the signal to 0 mV (0 degrees) when wind direction
is between 355 and 360 degrees.
The CR200(X) datalogger uses the ExDelSE() instruction to measure wind
direction. All other CRBasic dataloggers use the BRHalf() instruction. Edlog
dataloggers (CR510, CR10X, CR23X) use Edlog Instruction 4—Excite, Delay
(P4).
Some CRBasic measurement sequences cause the measurement of the wind
direction to return a negative wind direction (–30º) while in the dead band.
This can be overcome by using a delay of 40 ms (40,000µs) or by setting
negative wind direction values to 0.0: If WindDir < 0, then WindDir = 0.0.
The excitation voltage, range codes, and multipliers for the different datalogger
types are listed in TABLE 7-3. Appendix B has additional information on the
P4 and BRHalf() measurement instructions.

7.4.3 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.
7.4.4 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
7-4.

7.4.5 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. Theoretical
calculations indicate that 20 milliseconds is conservative.
For the CR200(X) datalogger, enter 20 ms for the Delay parameter of the
ExDelaySE() instruction. For other CRBasic dataloggers, increase the Settling
Time parameter of the BRHalf() instruction to 20 milliseconds (20,000
microseconds). For Edlog dataloggers, use Instruction 4—Excite, Delay (P4)
and enter a 2 in the Delay parameter. Edlog dataloggers cannot use a delay
when the 60 Hz rejection option is used.
Do not use long lead lengths in electrically noisy
environments.
CAUTION
8. 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 R.M. Young’s Propeller Torque Disc (pn 18310) as
described in the R.M. Young manual (see www.youngusa.com/products/7/).
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. The condition of the vertical shaft (vane) bearings can be
checked with R.M. Young’s Vane Torque Gauge (pn 18331).
