WindSonic 75
WindSonic ultrasonic anemometers offer high accuracy, low-cost wind measurement
- Industrial / infrastructure wind sensor (bridges, tunnels)
- Renewable energy site wind sensor
- Best ultrasonic anemometer for storm gust measurement
The Gill WindSonic 75 is a rugged 2-axis ultrasonic wind sensor designed to measure wind speed (0–75 m/s) and direction (0–360°) accurately without any moving parts, making it durable and maintenance-free. Built with a corrosion-resistant polycarbonate housing and rated IP66, it operates reliably in harsh environments such as marine, coastal, and industrial sites. The sensor supports multiple communication outputs—RS232, RS422, RS485, NMEA, Modbus, and optional analogue (0–5 V or 4–20 mA)—for easy integration into weather monitoring or control systems. With fast response time, high accuracy (±2 %), and a wide operating temperature range (−35 °C to +70 °C), the WindSonic 75 is ideal for professional meteorological, renewable energy, and environmental monitoring applications requiring robust, high-performance wind measurement.
