RM Young 05305 – AQ Wind Monitor Meets EPA Ambient Monitoring Guidelines – (AC Pulsed Wind Speed and Potentiometer Wind Direction)

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.
