ACO UST I C R E S O N A N C E W IN D S ENSOR 56.4mm U NI Q U E AC U -RES® T ECHNOLOGY Acoustic Resonance (Acu-Res®) is fundamentally different to other ultrasonic wind sensors, delivering exceptionally high levels of data availability. Incorporating a design legacy of 25 years and guaranteeing enhanced survivability, the FT7 series is widely used in wind turbine control systems, onshore and offshore, measuring wind speeds up to 75 m/s. Now introducing Advanced Sensor Diagnostics for enhanced fault monitoring. H I GH DATA AVAILABILIT Y The sensor is maintenance-free, reducing operational costs while delivering exceptionally high data availability. Industry-leading signal-to-noise ratio making it resistant to shock, vibration and EMI while ensuring reliable and accurate data acquisition. Additionally, the sensor is compact and lightweight for easy transport and handling. From freezing to lightning-prone areas across the world, the Flat Front sensor is designed for installation against a metal bar, easily aligned to the central axis of the turbine without error. Wind speed, direction, temperature and pressure data in a hard anodised aluminium body, highly resistant to corrosion, sand, dust, ice and solar radiation. The sensor is sealed to IP66, IP67 and IPX6K standard. Its lightning and surge protection safeguards against electrical disturbances, making it a reliable choice in the most demanding scenarios.
