R.M. Young Wind Sentry 5. 5. Wire according to the wiring diagram generated by Short Cut. Overview The 03002 Wind Sentry Set is used to measure horizontal wind speed and direction. Wind speed is measured with a three cup anemometer. Rotation of the cup wheel produces an ac sine wave voltage with frequency proportional to wind speed. This is a special version of the 03102 built for Campbell Scientific by R.M. Young that has shielded bearings rather than sealed bearings.
R.M. Young Wind Sentry The 03002's cable can terminate in: 6. • 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 03002 to be used in a wireless sensor network. Refer to www.campbellsci.com/cws900 for more information.

You do not need to read this section to use Short Cut. 7.4.1 Wind Speed Wind speed is measured with the Pulse Count instruction (PulseCount() in CRBasic and Instruction 3 in Edlog). Use the low level AC configuration. For dataloggers programmed with Edlog, specify configuration code 21 to output frequency in hertz.

Check that the sensor is wired to the excitation and single-ended channel specified by the measurement instruction. 2. Verify that the excitation voltage and range code are correct for the datalogger type. 3. Disconnect the sensor from the datalogger and use an ohm meter to check the potentiometer. Resistance should be about 10 kΩ between the black and white wires.

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.

Rt Rs EXCITATION VOLTAGE (Vx) SIGNAL + (Vs) AZIMUTH REFERENCE EARTH GROUND CONNECTION FIGURE B-1. 03002 and 03301 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).
Appendix B. Wind Direction Measurement Theory The maximum value that Rs will reach is Rf just before it crosses over from the west side of north to the east side of north (at this point Rt = 0). Vs reaches its maximum value of Vx. This maximum voltage equals 2500 mV for an excitation voltage of 2500 mV recommended for the CR10(X) and 5000 mV for an excitation voltage of 5000 mV recommended for the CR23X at 352 degrees. The multiplier to convert Vs to degrees is 352 degrees / 2500 mV = 0.

INTRODUCTION MODEL 03002-5 WIND SENTRY The Wind Sentry Anemometer and Vane measure horizontal wind speed and wind direction. The small size, simplicity, and corrosion resistant construction provide a professional quality instrument at a modest cost. The cup wheel and vane shafts use stainless steel precision instrument grade ball bearings which are lubricated with a wide temperature range high quality instrument oil.
FAILURE TO PROPERLY GROUND THE WIND SENTRY MAY RESULT IN ERRONEOUS SIGNALS OR TRANSDUCER DAMAGE. Grounding the Wind Sentry is vitally important. Without proper grounding, static electrical charge can build up during certain atmospheric conditions and discharge through the transducers. This discharge can cause erroneous signals or transducer failure. To direct the discharge away from the transducers, the instrument is made with a special anti-static plastic.
3. ALIGN VANE a) Connect excitation voltage and signal conditioning electronics to instrument according to wiring diagram. b) Loosen set screw in side of vane hub. c) Position instrument so crossarm is oriented north-south with vane on north side. Orient vane to a known angular reference. (See CALIBRATION section.) d) While holding vane in reference position, slowly turn vane skirt until signal conditioning system indicates proper value. e) Tighten set screw on side of vane hub.
