WS-2P Ultrasonic Wind Speed and Direction Sensor
Product Introduction
WS-2P Ultrasonic Wind Speed and Direction Sensor is an advanced ultrasonic anemometer designed for accurate and reliable wind field monitoring. It adopts ultrasonic time difference measurement technology and features a maintenance-free structure without any moving parts, making it an ideal replacement for traditional mechanical wind speed sensors.
The sensor uses a durable ABS engineering plastic housing with excellent resistance to pollution, corrosion, rain, and environmental aging. With optional heating modules, WS-2P can effectively eliminate the influence of rain, snow, and icing, enabling stable operation in harsh weather conditions and providing long-term reliable wind measurement data.

Product Features
• No moving parts, maintenance-free design
The ultrasonic measurement structure eliminates mechanical wear and reduces maintenance requirements, ensuring long service life and stable performance.
• Ultrasonic time difference measurement technology
The sensor measures wind speed and direction by calculating ultrasonic transmission time differences between transducers, providing fast response and high measurement accuracy.
• All-weather operation capability
Optional heating module helps prevent snow and ice accumulation, allowing continuous operation in extreme environments.
• High environmental adaptability
ABS engineering plastic housing provides excellent corrosion resistance and protection against dust, moisture, and outdoor environmental conditions.
• Multiple communication interfaces
Supports both analog and digital signal outputs, allowing easy integration with monitoring systems and data acquisition platforms.
• Flexible protocol compatibility
Supports ASCII, SDI-12, MODBUS, and NMEA communication protocols, with customized communication protocols available according to customer requirements.
• Wide application temperature range
Designed for outdoor applications with a working temperature range from -40℃ to +85℃.

Working Principle
WS-2P ultrasonic wind speed and direction sensor adopts ultrasonic time difference technology.
The sensor contains ultrasonic transducers that transmit and receive ultrasonic signals in different directions. When wind flows through the measurement path, the transmission speed of ultrasonic waves changes depending on the wind direction and velocity.
By calculating the difference in ultrasonic propagation time between different transmission paths, the sensor accurately determines:
• Wind speed
• Wind direction
Compared with mechanical anemometers, ultrasonic measurement eliminates errors caused by rotating components and is not affected by installation height, temperature, humidity, or atmospheric pressure variations, providing faster response and more reliable measurement results.
