1. Introduction
The 03002 Wind Sentry Set measures both wind speed and direction. It
consists of a 3-cup anemometer and a wind vane mounted on a small crossarm.
The anemometer (pn 03101) and vane (pn 03301) may be purchased
separately.
Before installing the 03002, please study
•Section 2, Cautionary Statements
•Section 3, Initial Inspection
•Section 4, Quickstart
2. Cautionary Statements
•The 03002 is a precision instrument. Please handle it with care.
•If the 03002 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 03002 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 03002, 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 List). 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
The 03002 Wind Sentry Set is used to measure horizontal wind speed and
direction.
Wind speed is measured with a three cup anemometer. Rotation of the cup
wheel produces an ac sine wave voltage with frequency proportional to wind
speed. This is a special version of the 03102 built for Campbell Scientific by
R.M. Young that has shielded bearings rather than sealed bearings. The
shielded bearings provide a lower starting threshold than sealed bearings.
Vane position is transmitted by a 10-kΩpotentiometer. With a precision
excitation voltage applied, the output voltage is proportional to wind direction.
The 03101 Anemometer and 03301 Vane can be ordered as separate sensors,
which are also covered in this manual. These two sensors combined differ
from the 03002 only by the absence of a junction box. The R.M. Young
Instruction Manual includes additional information on the operating principles,
installation, and maintenance of the sensor.
Cable length for the Wind Sentry is specified when the sensor is ordered.
TABLE 5-1 gives the recommended lead length for mounting the sensor at the
top of the tripod/tower with a CM200-series crossarm.

The 03002's cable can terminate in:
•Pigtails that connect directly to a Campbell Scientific datalogger
(option –PT).
•Connector that attaches to a prewired enclosure (option –PW). Refer
to www.campbellsci.com/prewired-enclosures for more information.
•Connector that attaches to a CWS900 Wireless Sensor Interface
(option –CWS). The CWS900 allows the 03002 to be used in a
wireless sensor network. Refer to www.campbellsci.com/cws900 for
more information.
6. Specifications
Features:
•Designed for continuous, long term, unattended operation in adverse
conditions
•Small size, simplicity, and rugged construction provide a quality
instrument for a modest price
•Ideal for wind profile studies
•Compatible with the LLAC4 4-channel Low Level AC Conversion
Module, which increases the number of anemometers one datalogger
can measure
•Campbell Scientific version uses shielded bearings, which lowers the
anemometer's starting threshold

7. Installation
7.1 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 wind set 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 10, References, for a list of references that discuss siting wind
speed and direction sensors.

The 03002 mounts to a standard 1.0 in. IPS schedule 40 pipe (1.34 in. O.D.).
A 12” long mounting pipe ships with the 03002. The mounting pipe typically
fastens to a CM200-series crossarm via the CM220 mount or 17953 NU-RAIL
fitting. Section 4, Quickstart, describes mounting the 03002 using a CM220
mount or a 17953 NU-RAIL fitting. The 03002 can also be mounted at the top
of a CM110, CM115, or CM120 tripod with the CM216 (see FIGURE 7-1).

7.4 Programming
This section is for users who write their own programs. A datalogger program
to measure this sensor can be created using Short Cut. You do not need to read
this section to use Short Cut.
7.4.1 Wind Speed
Wind speed is measured with the Pulse Count instruction (PulseCount() in
CRBasic and Instruction 3 in Edlog). Use 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 7-3 lists the multipliers (M) and offsets (Off) to obtain meters/second
or miles/hour when the Pulse Count instruction is configured to output the
result in hertz.
TABLE 7-3. Wind Speed Multiplier
(With Pulse Channel Configuration Set to Low Level AC, Output “Hz”)
Model Meters/Second Miles/Hour
03002 / 03101 M = 0.750
Off = 0.2
M = 1.677
Off = 0.4
*When the pulse channel configuration is set to Low Level AC, output
“counts”, the multiplier above is divided by the execution interval in seconds.
7.4.2 Wind Direction
The wind vane is coupled to a 10 kΩpotentiometer, which has a 8 degree
electrical dead band between 352 and 360 degrees.
The CR200(X) dataloggers use 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).
Excitation voltages, range codes, and multipliers for Campbell Scientific
dataloggers are listed in TABLE 7-4. Appendix B has additional information
on the 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) from the measured wind speed and direction values.
7.4.4 Example Programs
The following programs measure the 03002 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 7-5.
