8. If
LoggerNet
,
PC400
,
RTDAQ
, or
PC200W
is running on your PC, and the
PC to datalogger connection is active, you can click Finish in Short Cut
and you will be prompted to send the program just created to the
datalogger.
9. If the sensor is connected to the datalogger, as shown in the wiring
diagram in step 6, check the output of the sensor in the datalogger support
software data display to make sure it is making reasonable measurements.
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 k
Ω
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.
The wind monitors are manufactured by R.M. Young and cabled by Campbell
Scientific for use with our dataloggers. Lead lengths for the wind monitors are
specified when the sensors are 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.
TABLE 5-1. Recommended Lead Lengths
CM106 CM110 CM115 CM120 UT10 UT20 UT30
13 ft 13 ft 19 ft 24 ft 13 ft 24 ft 34 ft
Maximum cable length is 1000 feet.
Do not use long lead lengths in electrically noisy
environments.
The wind monitor’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 wind monitor to be used in
a wireless sensor network. Refer to
www.campbellsci.com/cws900
for
more information.
