Order Info
The Wind Monitor is a high performance wind speed and direction sensor manufactured by R.M. Young Company and designed specifically for air quality measurements. It combines simplicity and lightweight corrosion resistant construction with low threshold, fast response and excellent fidelity.
The wind speed sensor is a four blade helicoid propeller. Propeller rotation produces AC sine wave voltage signal with a frequency directly proportional to wind speed. Slip rings and brushes are not used.
The wind direction sensor is a lightweight vane with sufficiently high damping ratio and low aspect ratio to assure excellent fidelity in rapidly fluctuating winds. Vane position is sensed by a precision conductive plastic potentiometer. With a known excitation voltage applied to the potentiometer, the output signal is directly proportional to the azimuth angle.
The instrument is made of UV stabilized plastic with stainless steel and anodized aluminium fittings. All bearings are stainless steel precision grade.
A micro-power interface circuit, housed in a convenient junction box on the mounting post, converts the AC sine wave to a 5V signal and potentiometer output to a calibrated 2.50V signal, suitable for connection to the data logger.
A 8 core cable (Model 6600F) can be used to connect the instrument to the logger. The instrument mounts on standard 1 inch pipe.
