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.

Connections to Campbell Scientific dataloggers are given in Table 4-1. When

Short Cut for Windows software is used to create the datalogger program, the

sensor should be wired to the channels shown in the wiring diagram created by

Short Cut.

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.
