05103, 05103-45, 05106, and 05305 R.M. Young Wind Monitors
The R.M. Young Instruction Manual includes additional information on the
operating principles, installation, and maintenance of the sensor.
The Wind Monitors are manufacturered 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

13 ft 13 ft 19 ft 24 ft 13 ft 24 ft 34 ft
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.
