![]() ![]() ![]() ![]() It is perfectly suited for applications requiring fast. We are ISO 9001 and ISO 14001 certified, and all of our wind sensors undergo a rigorous battery of vibration and shock, waterproofing and sealing, temperature and EMC tests to ensure reliable service, even in the harshest of environments. The RM Young 81000 Ultrasonic Anemometer is a high-quality 3-axis wind sensor with no moving parts. The dust exposure testing showed that coal dust rarely affected the ultrasonic anemometers and was easy to clean off of the instruments. The effects of two different dusts, rock dust and coal dust were evaluated. Ultrasonic anemometers allow the measurement of quickly changing wind parameters thanks to their acoustic measuring principle. With full 360° air speed direction measurement, they are ideal for station-keeping and hovering on quad-rotor UAVs, as well as dynamic positioning control in gusty and turbulent environments. Two ultrasonic anemometers were assessed in the laboratory, for the influence of dust deposition. The drone anemometers achieve high accuracy within the measured air speed range of 0-75m/s, and have been used as a pitot tube replacement on fixed-wing UAVs. The small footprint, light weight and ease of integration of our anemometer sensors make them ideal for meteorological applications in the defense and aerospace sectors, such as on board unmanned vehicles and at UAV (unmanned aerial vehicle) ground launch and recovery stations. Our ultrasonic wind sensors are compact, lightweight and deliver reliable wind speed and direction data in the toughest of climates and weather conditions. For the determination of local Cn2 values, 3D ultrasonic anemometers of type. FT Technologies is a specialist designer and manufacturer of high-performance Acoustic Resonance wind sensors, also known as anemometers. Designed and manufactured by Gill Instruments in the UK, Gill Research 3-axis ultrasonic anemometers provide high accuracy with fast and reliable output rates. ![]()
