05103, 05103-45, 05106, and 05305 R.M. Young Wind Monitors 1. Introduction The 05103, 05103-45, 05106, and 05305 Wind Monitor sensors are used to measure horizontal wind speed and direction. The 05305 is a high performance version of the 05103 designed to meet PSD specifications for air quality applications. The 05103-45 is an alpine version that discourages ice buildup. The 05106 is recommended for marine applications. Before installing the Wind Monitor, please study • • • 2. 3.

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 kΩ potentiometer.
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.

Generally, there should be a horizontal distance of at least ten times the height of the obstruction between the windset and the obstruction. If the sensors need to be mounted on a roof, the height of the sensors above the roof, should be at least 1.5 times the height of the building.

When Short Cut for Windows software is used to create the datalogger program, the sensor should be wired to the channels shown in the wiring diagram created by Short Cut. TABLE 7-1.

05103, 05103-45, 05106, and 05305 R.M. Young Wind Monitors The expression for wind speed (U) is: U = Mx + B where M = multiplier x = number of pulses per second (Hertz) B = offset TABLE 7-2 lists the multipliers to obtain miles/hour or meters/second when the measurement instruction is configured to output Hz. The helicoid propeller has a calibration that passes through zero, so the offset is zero (Gill, 1973; Baynton, 1976). TABLE 7-2.

05103, 05103-45, 05106, and 05305 R.M. Young Wind Monitors NOTE 9. Often Campbell Scientific recommends factory replacement of the bearings and potentiometer. Refer to the Assistance page of this document for the procedure of acquiring a Returned Materials Authorization (RMA). Mechanically-adept users may choose to replace the bearings or potentiometer themselves. Instructions for replacing the bearings and potentiometer are given in R.M. Young’s manuals (www.youngusa.com/products/7/).
05103, 05103-45, 05106, and 05305 R.M. Young Wind Monitors Symptom: Wind speed does not change 1. For the dataloggers programmed with Edlog, the input location for wind speed is not updated if the datalogger is getting “Program Table Overruns”. Increase the execution interval (scan rate) to prevent overruns. 10. References Gill, G.C., 1973: The Helicoid Anemometer Atmosphere, II, 145–155.

Appendix A. Wind Direction Sensor Orientation A.1 Determining True North and Sensor Orientation Orientation of the wind direction sensor is done after the datalogger 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.

FIGURE B-1. 05103 potentiometer in a half bridge circuit B.1 BRHalf Instruction The BRHalf instruction outputs a precise excitation voltage (Vx), and measures the voltage between the wiper and ground (Vs). The resistance between the wiper and ground, Rs, and Vs varies with wind direction.
Appendix B. Wind Direction Measurement Theory B.2 EX-DEL-SE (P4) Instruction Instruction 4 outputs a precise excitation voltage (Vx) and measures the voltage between the wiper and analog ground, Vs. The resistance between the wiper and analog ground, Rs, and Vs varies with wind direction. Instruction 4 outputs the measured voltage, Vs.
