The 05108-45-L40 Wind Monitor-HD is a lightweight instrument that measures wind speed and wind direction. It is designed to prevent ice buildup, allowing the sensor to provide you with accurate measurements in harsh alpine conditions that have limited accessibility. Manufactured by R. M. Young, this wind monitor is cabled for use with Campbell Scientific data loggers.Read More

Please note: The following shows notable compatibility information. It is not a comprehensive list of all compatible products.
|CR500 (retired)||Measurements are typically processed for output with the Wind Vector instruction, which is not present in the CR500 or CR9000.|
|CR9000 (retired)||Measurements are typically processed for output with the Wind Vector instruction, which is not present in the CR9000.|
The 05108-45-L can be attached to a crossarm via a 17953 Nu-Rail Crossover Fitting or CM220 Right-Angle Mounting Bracket. Alternatively, it can be attached to the top of a CM106B or stainless-steel tripod via the CM216 Sensor Mounting Kit.
Wind profile studies measure many wind sensors. For these applications, the LLAC4 4-Channel Low Level AC Conversion Module can be used to increase the number of Wind Monitors measured by one data logger. The LLAC4 allows data logger control ports to read the wind speed sensor’s ac signals instead of using pulse channels. Data loggers compatible with the LLAC4 are the CR200(X) series (ac signal ≤1 kHz only), CR800, CR850, CR1000, CR3000, and CR5000.
The 05108-45's propeller uses one pulse count channel on the data logger. Its wind vane requires one single-ended channel and access to an excitation channel. (The excitation channel can be shared with other high-impedance sensors.)
The 05108-45's propeller is measured by the PulseCount Instruction in CRBasic and by Instruction 3 (Pulse Count) in Edlog. The wind vane is measured by the BrHalf Instruction in CRBasic and by Instruction 4 (Excite-Delay-SE) in Edlog. The measurements are typically processed for output with the Wind Vector instruction (not present in the CR500 or CR9000 but present in the CR9000X).
