WSD-QD Dual Wind Speed and Direction Sensor
- Wind speed and direction combined within a single sensor
- Durable aluminum and stainless steel construction
- Low starting threshold
- Stainless steel bearings
- Easy, quick installation
- Highly accurate
- Low power consumption
The WSD-QD is designed to operate in temperatures ranging from -30°C to +70°C and wind speeds of up to 155mph (not recommended for heavy snow and ice conditions). Wind speed measurements are obtained through the use of a sealed reed switch, providing a series of pulses proportional to wind speed. The wind speed sensor is equipped with aluminum cups for durability. Wind direction is measured with an aluminum vane coupled to a precision potentiometer.
The WSD-QD has been field proven over many years and has demonstrated its reliability under remote, hostile conditions.
