Ultrasonic Anemometer PCE-WS US2

The PCE-WS US2 ultrasonic anemometer is designed for precise measurement of wind speed and direction using ultrasonic transducer technology. By eliminating moving parts, unlike traditional mechanical cup anemometers, it avoids mechanical wear, ensuring greater durability and reliability.

With its robust construction, the PCE-WS US2 is ideally suited for demanding industrial environments. It offers strong resistance to electromagnetic and radio frequency interference. Its IP65-rated housing ensures full protection against dust and water, making it ideal for outdoor use.

The device supports RS485 communication with Modbus RTU protocol, ensuring compatibility with modern industrial automation and monitoring systems. Its compact design allows for simultaneous wind speed and direction measurement in a single unit, reducing installation space and complexity when compared to traditional anemometers and wind vanes.

Typical applications:

• Suitable for solar trackers;
• Irrigation control systems;
• greenhouse automation;
• Wind turbines;
• Cranes;
• Weather stations and other scenarios where wind monitoring is essential for safety and process optimization.
