The Wind Monitor-AQ is a high
resolution wind sensor designed
specifically for air quality applications.
It combines simple, corrosion-
resistant construction with
low threshold, fast response and
excellent fidelity.
The Wind Monitor-AQ meets the requirements
of the following regulatory agencies:
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. Propeller rotation produces an AC sine wave voltage signal with frequency directly
proportional to wind speed. Slip rings and brushes are not used.
The wind direction sensor is a lightweight vane with performance characteristics that
assure excellent fidelity in fluctuating wind conditions. Vane position is sensed by a precision
potentiometer. Output is a DC voltage directly proportional to vane angle.
The instrument body is UV stabilized plastic with stainless steel and anodized aluminum
fittings. Precision grade, stainless steel ball bearings are used throughout. Transient
protection and cable terminations are located in a convenient junction box. The instrument
mounts on standard 1 inch pipe.
The Wind Monitor-AQ is available with two additional output signal options. Model
05305V offers calibrated 0 -1 VDC outputs (0-5 VDC optional), convenient for use with many
dataloggers. Model 05305L provides a calibrated 4-20 mA current signal for each channel,
useful in high noise areas or for long cables (up to several kilometers). Signal conditioning
electronics are integrated into the sensor junction box.
