Ultrasonic Wind Sensors Enhance Wind Farm Safety and Efficiency Amid Extreme Weather

Wind farms are widely distributed, often located in high-altitude areas with complex environments and harsh climates. Especially in extreme weather such as ice, snow, and strong winds in winter, three-cup wind speed sensors and mechanical wind vanes are affected by ice and other weather conditions, which will seriously affect the safety of wind turbine operation and power generation efficiency. Firstrate's anti-freezing ultrasonic wind speed and direction sensor FST200-207, with advanced technology and professional design, is tailored for the wind power industry and provides reliable support for wind farm operations.

In the face of cold weather in winter, especially after rain and snow, traditional three-cup wind speed sensors are prone to water accumulation and ice formation at the sensor bearings, causing the sensor to be unable to rotate normally. After freezing, manual deicing is required, which not only increases maintenance costs, but may also affect the accuracy of observation data. In addition, the wear and aging of mechanical parts will cause the accuracy and stability of the sensor to gradually decrease, especially in severe weather conditions.

The ultrasonic wind speed and direction sensor uses a fully solid-state ultrasonic sensing technology without mechanical structure to accurately measure wind speed and wind direction without direction restrictions. Multiple probes are interconnected and collaborated in real time to ensure accurate and fast output of measurement data. The wind speed measurement range can reach 0~60m/s, with an error of only ±0.3m/s, and the wind direction error is controlled at ±2°, providing a solid data basis for the attitude adjustment of wind turbines.

The working principle of the anti-freezing ultrasonic wind speed and direction meter is to use the ultrasonic time difference method to measure wind speed. The speed of sound propagation in the air will be superimposed with the airflow speed in the wind direction. If the propagation direction of the ultrasonic wave is the same as the wind direction, its speed will increase; conversely, if the propagation direction of the ultrasonic wave is opposite to the wind direction, its speed will slow down. Therefore, under fixed detection conditions, the speed of ultrasonic wave propagation in the air can correspond to the wind speed function. Accurate wind speed and wind direction can be obtained by calculation. Since the speed of sound waves is greatly affected by temperature when they propagate in the air: the anemometer detects two opposite directions on two channels, so the effect of temperature on the speed of sound waves can be ignored. Users can select wind speed units, output frequency and output format according to their needs.

Anti-freezing ultrasonic wind speed and direction sensors have unique advantages. The ultrasonic emission and reflection surface covers are equipped with high-power heating devices, and the heating function starts and stops automatically to ensure that the sensor can work normally under extremely low temperature conditions. The original aluminum alloy integrated appearance design has a beautiful appearance and uses advanced sensing technology for real-time measurement. There is no start-up wind speed limit, no angle limit, and wind speed and wind direction data are obtained at the same time, which can truly achieve all-weather operation. It can be widely used in remote areas such as mountains and islands with harsh environments.

As an important part of green energy, wind power cannot be separated from high-performance environmental monitoring equipment for its safe and efficient operation. Anti-freezing ultrasonic wind speed and direction sensors are creating a stable and reliable meteorological perception foundation for wind farms with their excellent quality and strong environmental adaptability.
