Description
Ultrasonic Anemometer – 3S-WS&WD-US
The SEVEN Ultrasonic Anemometer is a high-precision, two-axis sensor designed to measure wind speed and direction in all environmental conditions. It can measure wind speeds up to 85 m/s and withstands extreme conditions, including aggressive environments thanks to an optional anodized aluminum alloy case with anti-corrosion coating. A heating option allows for quick defrosting, making it ideal for cold climates. The device also meets MIL-STD-810G Method 509.6 for salt spray corrosion and offers high immunity to electromagnetic interference.
Data is transmitted via RS485 Modbus RTU and two factory-configurable analog outputs, compatible with standard ranges (4–20 mA, 0–1 V, 0–5 V, or 0–10 V). The anemometer is factory-calibrated and ready to use without additional adjustments.
