Mounting
The 05103 can be attached to a CM202, CM202SS, CM203, CM204, CM204SS, or CM206 crossarm via a 17953 Nu-Rail fitting or CM220 Right-Angle Mounting Kit. Alternatively, the 05103 can be attached to the top of our stainless-steel tripods via the CM216 Sensor Mounting Kit. Please note that a lightning rod cannot be used when the CM216 attaches a 05103 atop the tripod’s mast. Therefore the CM216 is only recommended for mounting these sensors if the deployment is short term.
Wind Profile Studies
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.
Data Logger Considerations
The 05103'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).
Programming
The 05103'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 is present in the CR9000X).

-
This depends on what is broken. Typically, Campbell Scientific can repair the unit, and the user does not have to purchase a new one.
-
The measurement instructions will likely remain the same. However, in addition to the multiplier and offset, the type of pulse may change for the wind speed, and the excitation voltage may change for the wind direction. For an explanation of how the data logger needs to be programmed, see the instruction manual.
-
The short answer is less than 0.01 mA. The wind speed signal requires no power. The wind direction portion of the sensor only uses a maximum of 0.5 mA when excited with 5 Vdc, and then it is only on for 0.016 s for every measurement. When the wind direction is measured every second (typical), the average current drain is less than 0.01 mA.
-
Yes, but this is not a standard product that Campbell Scientific offers. We can, however, order one from the manufacturer (R. M. Young).
-
Orientation of the wind monitor is done after the data logger has been programmed, and the location of True North has been determined. True North is usually found by reading a magnetic compass and applying the correction for magnetic declination, where magnetic declination is the number of degrees between True North and Magnetic North. Magnetic declination for a specific site can be obtained from a USFA map, local airport, or through a computer service.
-
R. M. Young, the manufacturer of this sensor, recommends a maximum cable length of 300 m (984.25 ft) between the wind monitor and a data system/display. For longer cable runs, either the Line Driver (4 to 20 mA outputs) or the Serial Interface (RS-485) is suggested.
-
- Using Short Cut, click the applicable wind direction sensor in the Selected Sensors list of the Outputs screen.
- The two output options enabled are Sample and WindVector. Select WindVector.
- The WindVector instruction has output options. Select an option with mean wind direction in it.
