Anti-Freezing Ultrasonic Wind Sensor Application in Wind Power Industry

In the wind power industry, accurate monitoring of wind speed and direction is the first line of defense to ensure efficient power generation and equipment safety. However, when biting cold winds bring snow and ice, traditional anemometers often fail due to frozen moving parts, resulting in inaccurate readings or complete measurement failure.

To meet this challenge, FIRSTRATE has developed the FST200-207 ultrasonic wind speed and direction sensor, designed for extreme cold conditions. Its innovative self-heating function effectively prevents icing and ensures stable operation even in freezing rain and snow. This ensures continuous, accurate data output and solves the long-standing problem of sensors freezing in cold climates.

In an ever-changing wind environment where every second of data is critical, the FST200-207 uses ultrasonic time-difference technology to measure wind speed and direction with starting thresholds as low as 0.1 m/s and a response time of 1 second. With high accuracy and reliability, no moving parts, maintenance-free, and no need for on-site calibration, it is a state-of-the-art wind speed measurement tool. It overcomes the inherent limitations of mechanical anemometers and proves to be a robust and reliable alternative, capable of continuous operation in all weather conditions.

With an IP66 protection rating, this sensor is built to withstand extreme cold, high humidity, and even sandy or windy environments. Whether deployed in northern inland wind farms facing severe cold, or southern regions with highly variable weather, the sensor demonstrates excellent adaptability. It not only resists freezing temperatures but also withstands strong wind gusts and other environmental challenges.

Whether for new wind power installations or for upgrading older monitoring systems, the FST200-207 is an ideal choice for enhancing system reliability. It has become an essential tool in the wind energy sector—not just a sensor, but a smart guardian that ensures the safe and efficient operation of wind turbines, using technology to protect performance even in the harshest winters.
