ACOUSTIC RESONANCE WIND SENSOR B The FT722 Flat Front wind sensor is designed for quick and easy installation against a metal bar. The bar allows the sensor to be aligned to the central axis of the turbine without error. Ideal for retrofit, the sensor provides a single, compact solution to replacing an existing mechanical wind vane and anemometer wind measurement system. With no moving parts to wear out or degrade, turbine downtime is reduced, power output is increased and yaw control is more efficient. With updated software and improved accuracy, it is also a fit and function replacement for the FT702LT-FF sensor. The FT722-FF has sufficient heating capacity to keep itself ice-free and to heat the mounting bar. This prevents ice from building up and blocking air flow through the measurement cavity. It has passed over 30 environmental tests to demonstrate its durability. SPECIFICATIONS AT A GLANCE WIND SPEED WEIGHT AVAILABILITY THE WORLD’S TOUGHEST WIND SENSORS
