05103, 05106, and 05305 R.M. Young
Wind Monitors
1. Introduction
These notes provide information for interfacing Campbell Scientific’s
dataloggers to the R.M. Young 05103 Wind Monitor, 05106 Wind Monitor
Marine, and 05305 Wind Monitor AQ. The 05305 Wind Monitor AQ is a high
performance version of the Wind Monitor that is designed specifically for air
quality measurements. Wiring is identical for all models. R.M. Young's
instruction manual, included with the sensor, contains sensor specifications,
operating principles, installation and alignment guide, and calibration
information. Multiplier and offset values in the Campbell Scientific notes are
based on calibration data obtained from the R.M. Young Wind Monitor
manual.
2. Mounting Requirements
The Wind Monitor mounts to a vertical piece of 1" IPS schedule 40 (1.32"
O.D.) pipe. (See Figure 2-1.) A band clamp at the base of the sensor is
tightened to secure the sensor to the pipe.
Campbell Scientific supplies a 12" length of unthreaded pipe for mounting the
wind monitor to Campbell Scientific's 019ALU Crossarm Sensor Mount
(Figure 2-2).

3. Sensor to Datalogger Wiring
Wire the Wind Monitor leads to the datalogger (see Figure 3-1).
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.

4. Programming
This section is for users who write their own datalogger programs. A
datalogger program to measure this sensor can be created using Campbell
Scientific’s ShortCut Program Builder software. You do not need to read this
section to use ShortCut.
4.1 Wind Speed
Wind speed is measured with the pulse count instruction. The wind vector
instruction is used to calculate average wind speed and direction. With the
pulse count instruction, specify a low level AC configuration, discarding counts
from excessive intervals, and the result in Hz. With this configuration, the
pulse count instruction divides the number of counts during the execution
interval by the interval in seconds before applying the multiplier and offset.
The expression for wind speed (U) is:
U= MX+B
where
M = multiplier
X = number of pulses per second
B = offset
Table 4-1 lists the multipliers to obtain miles/hour or meters/second when the
pulse count instruction is configured to provide its result in Hz. The helicoid
propeller has a calibration that passes through zero; use an offset of zero (Gill,
1973; Baynton, 1976).
TABLE 4-1. 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.

21Xs without OSX PROMS and CR7s without OS7 PROMS
(dataloggers purchased prior to March 1989 and August 1991
respectively, and not updated) do not have the option of
outputting frequency in hertz. Program Instruction 3 with
configuration code 11 (pulses per execution interval). The
multiplier from Table 4-1 is divided by the execution interval in
seconds to obtain the multiplier used with code 11. For example,
with a 10-second execution interval, the multiplier for
meters/second with the 05103 would be 0.0980/10 = 0.0098.
The offset remains zero.
4.2 Wind Direction Instruction Code
The wind direction sensor is a potentiometer that is measured as a “half
bridge”. The output ranges from 0 mV at 0 degrees to the excitation voltage at
355 degrees. In dataloggers programmed with Edlog, measure the wind
direction with Instruction 4 (Excite, Delay, and Measure). CR200 series
dataloggers use the ExDelSE instruction and other CRBasic dataloggers use the
BRHalf instruction. In general, a delay of 1 (0.01 seconds) is sufficient when
lead lengths are less than 100 feet. If the cable is 100 to 1000 feet, use a delay
of 5 (0.05 seconds). The wind direction potentiometer has a five degree
deadband between 355 and 360 degrees; therefore, the maximum signal is at
355 degrees. The result of the BRHalf instruction prior to applying the
multiplier is measured mV/Excitation mV; therefore, the multiplier is 355. The
other measurement result is the measured mV; the multiplier with these
instructions is 355/Excitation Voltage. The offset is zero. The parameters to
be used with each datalogger are listed in Table 4-2.

5. Maintenance and Repairs
R.M. Young suggests the anemometer bearings be inspected at least every 24
months. Please refer to the R.M. Young manual for maintenance information.
Contact R.M. Young's customer service department directly to obtain repair
cost estimates and authorization for return of the unit. Their phone number is
