YOUNG, AQ Wind Monitor Meets EPA - PSD Model 05305[12 Oct. 2011, 0:09:34]
The Wind Monitor-AQ is a high resolution wind sensor for air quality applications. It combines low threshold, fast response and excellent fidelity to meet important regulatory standards.
U.S. Environmental Protection Agency – Ambient Monitoring Guidelines for Prevention of Significant Deterioration ( PSD) .
U.S. Nuclear Regulatory Agency – NRC Regulatory Guide 1.23 Meteorological Programs in Support of Nuclear Power Plants.
American Nuclear Society – Standard for Determining Meteorological Information at Power Plants.
Wind speed is sensed by a lightweight, carbon fiber thermoplastic ( CFT) , helicoid propeller. The wind direction sensor is a lightweight, balanced vane. The instrument body is UV stabilized plastic with stainless steel and anodized aluminum fittings. The instrument mounts on standard 1 inch pipe. The Wind Monitor-AQ is available with two additional output signal options: Model 05305V offers calibrated voltage outputs. Model 05305L provides 4-20 mA current signals.
