FT702LT Turbine control wind sensor... ...gives durability a new meaning

Proven High Availability The FT702LT ultrasonic anemometer is the result of FT Technologies’ 10 years of experience in designing durable turbine control wind sensors for the demanding environment outside a wind turbine. Users typically experience data availability of more than 99.9% as the ultrasonic anemometer keeps on working in many adverse environments where traditional sensors fail. These high levels of availability are achieved through the use of Highly Accelerated Lifecycle Testing during design, an extensive independent testing programme and a robust solid state design with no moving...

Reliable Environmental Protection System The Acu-Res EPS means the sensor works reliably in the most extreme conditions and helps to guarantee high data availability. The EPS incorporates: Eight sensors were independently calibrated prior to the following accelerated life tests. Robust, compact form Designed for: Impact Tested and Proven: Drop resistant: EN 60068-2-31 (2008) dropped 6 times at different angles from 1 metre onto steel faced concrete. Tested and Proven: Hail resistant: EN 61215 (2005) 10 hail stones, 7.5 grams each shot at the sensor at 23 m/s. hail Hard anodised alloy body Designed...

Technology This is FT Technologies’ patented Acoustic Resonance technology. Acu-Res enables our sensors to take accurate measurements in a small space. This means our sensors are small, easy to heat, durable and strong. Acu-Res sets FT sensors apart from mechanical and other ultrasonic wind sensing technologies to give a more robust and reliable measurement solution. The sensor works by creating a resonating ultrasonic signal inside the sensor’s measurement cavity. The motion of air is sensed by measuring the phase change in the ultrasonic signal caused by the wind as it passes through the cavity....

Wind direction Wind speed Range 0-50m/s Accuracy ±2° (within ±10° datum) Sensor performance Measurement principle Acoustic Resonance (automatically compensates for variations in temperature, pressure & humidity). Altitude 0-4000m operating range. Temperature range -40° to +85°C (operating and storage) Heater settings 0° to 55°C. The heater set point can be configured. 4A (default), 0.1-6A (max) - Configurable in software. Heater power consumption will depend on the energy required to keep the sensor's temperature at the user determined set point. The heater and sensor power consumption is limited...

Product Range Flat Front (FF) Digital Sensors Analogue Sensors Acu-Test Packs These comprise Acu-Vis software and a specially developed cable which allows connection to a Windows PC and to a power supply. For the analogue sensor the software allows the functioning of the sensor to be checked and configuration changes to be made. For the digital sensor the software displays the sensor’s settings and shows wind speed and direction in real time. FT089 Pipe Mount Adapter This enables the pipe mount version of the wind sensor to be easily and securely mounted on to a pipe. It gives improved grounding...
