RK120-02 Ultrasonic Wind Speed & Direction Sensor is a testing instrument for measuring wind speed and wind direction by acquiring time differences of ultrasonic propagation in the air. It can be used in wild harsh environment such as cryogenics & freezing rain. Compared with mechanic wind sensors,Ultrasonic Wind Speed & Direction Sensor features no wear, long service life, and fast response rate, free maintenance, no on-site calibration required. It is a robust construction with strong anti-corrosion, light weight and easy installation & removal. RK120-02 can be widely used in environmental & meteorological monitoring, wind power generation, bridges, tunnels, marine shipping, aviation airports, and other fields.
