WindMaster - 3D - Sonic Anemometer Datasheet

3-Axis Ultrasonic AnemometerThe Gill WindMaster is a precision anemometer offering three-axis wind measurement data. This instrument will monitor wind speeds of 0-45m/s and provides sonic temperature, speed of sound and U, V & W vector outputs at 20Hz (32Hz optional). This anemometer is of aluminium/carbon fibre construction and is ideal for the understanding of turbulent flows, surface energy balance and scalar fluxes. Each WindMaster is calibrated with a Gill wind tunnel test to provide optimum performance.This 3D sonic anemometer is ideally suited to the measurement of air turbulence around bridges, buildings, wind turbine sites, building ventilation control systems, meteorological and flux measurement sites.Anemometer 9-30 VDC (55mA @ 12 VDC)Range 0 - 45 m/sResolution 0.01 m/sAccuracy* <1.5% RMS @12 m/sAccuracy* <1% RMS @12 m/s (Custom)Range 0 - 359°Resolution 0.1°Accuracy 2° @12 m/sAccuracy 0.5° @12 m/s (Custom)Communication RS232, 422, 485Baud Rates 2400 - 115200Format ASCIIPower RequirementWind SpeedDirectionDigital OutputRange 300-370 m/sResolution 0.01 m/sAccuracy < ±0.5% @ 20°CSpeed of SoundRange -40°C to +70°CResolution 0.01°CSonic TemperatureMechanicalResolution 12 bits or 14 bits 4 channels availableSelectable Range User selectable full scale wind speedOutput type 0-20mA, 4-20mA, 0-5 V, ±2.5 V, ±5 VAnalogue Outputs - OptionalWeight 1.0 kgSize 750mm x 240mmMeasurementInternal sample rate 20 Hz or 32 HzOutput Parameters 1, 2, 4, 8, 10, 16, 20 & 32 (Option) HzUnits of Measure m/s, mph, kph, knots, ft/minFormats UVW, Polar or NMEAAveraging Flexible 0-3600 sResolution 12 bits or 14 bits Up to 4 single ended or 2 differentialInput Type ±5 VAnalogue Inputs - Optional*Accuracy spec applies for wind speed, and for wind incidence up to ±30° from the horizontalEnvironmentalProtection Class IP65Operating Temp -40°C to +70°CHumidity < 5% to 100% RHPrecipitation 300mm/hrEMC BS EN 61000 - 6 - 3 (Emissions)BS EN 61000 - 6 - 2 (Immunity)Key FeaturesPrecision 3-axis sonic anemometer20Hz Output Rate (32Hz Optional)0-45m/s wind speed 0-359º wind directionU, V, W Vector OutputsAluminium/Carbon Fibre ConstructionSonic temperature outputOptional custom calibrationINSTRUMENTSPower LinesBridgesViaductsBuilding ventilation control systemsMeasurement MastsSkyscrapersWind Turbine Test SitesMeteorological & Flux measurement sitesTypical ApplicationsINSTRUMENTSGill Instruments Ltd Saltmarsh Park67 Gosport StreetLymingtonHampshireSO41 9EG, UKT: +44 (0) 1590 613 500F: +44 (0) 1590 613 555E: [email protected] © Gill Instruments 2012D1304 - Iss 2Gill Instruments LtdReg No. 3154453 Registered Office: The George Business Centre, Christchurch Road, New Milton, BH25 6QJThis product is in continuous development and therefore specifications may be subject to change without prior notice.3-Axis Ultrasonic AnemometerØ100mm (3.9")Ø57mm (2.25")Ø240mm (9.45")Top viewPositions for three off bolt fixings with Ø7.0mm (0.27") max. thread.on a p.c.d. of 85mm (3.35")254mm (10")233mm (9.2")750mm (29.5")North alignment symbol and notch
