FT702LT U L T R A S O N I C HEAVY DUTY W I N D S E N S O R WIND SPEED AND WIND DIRECTION IN ONE TOUGH PACKAGE FT702LT series
Proven High Availability The FT702LT ultrasonic anemometer is the result of FT Technologies 10 years of experience in designing durable wind sensors for demanding environments. 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 parts to degrade. The sensor is probably the most tested wind sensor in the world. It has passed over 28 independent tests including sand, dust, ice, vibration, drop, corrosion, hail and lightning protection. Powered by our patented Acu-Res technology the FT702LT delivers reliable measurements for many years. All our sensors are 100% wind tunnel checked before dispatch to ensure that the sensors will give long and reliable service. Powerful De-Icing The sensor is fitted with a thermostatically controlled all-body heating system. The sensor maintains its temperature at a user specified heater set point of between 0⁰C and 55⁰C. Three software controlled heaters are used to distribute heat intelligently over the entire sensor. In standard format the heaters draw a maximum of 99W. For extreme environments the current limit can be adjusted (power supply and cabling permitting) from 0.1 to 6 Amps. The heaters can also be switched off and then current draw falls to 25mA. Proven Lightning Protection Wind sensors may be exposed to high levels of electromagnetic interference from static discharges and nearby lightning strikes. The sonic FT702LT incorporates robust protection circuitry to shield it against these effects. The sensor will survive undamaged lightning induced surges in excess of 4kA 8/20μs. Installation Flexibility The FT702LT series has two physical mounting options. The flat front mounting for fitment to a bar or the pipe mount system for fitment to a pipe. The pipe mount system gives improved environmental protection as the communication and power cable is kept fully protected inside the pipe. Used Everywhere The FT702LT series has been in use for over 10 years. In that time more than 65,000 sensors have been installed all over the world from Mongolia to Alaska. The sensor is used in meteorology, on wind turbines, on buildings, on railways, on armoured vehicles and at both of the Poles. PIPE MOUNT SYSTEM

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. The sensor has three transducers arranged in an equilateral triangle. The net phase difference between a transmitting and receiving transducer pair is indicative of the airflow along the axis of the pair and by measuring all three pairs the component vectors of the airflow along the sides of the triangle are determined. These vectors are combined to give the overall speed and direction. The sensor uses complex signal processing and data analysis taking a sequence of multiple measurements to calculate regular wind readings. 1. Resonance is initiated by a transducer transmitting an ultrasonic signal into the measurement cavity. Transducer transmits ultrasound 2. In order to achieve resonance, the wavelength of the transmitted signal is made to match the resonance wavelength of sound inside the cavity. Signal resonates in cavity 3. Changes in the properties of the resonating signal caused by a change in the speed of sound are automatically detected and corrected by the digital processing engine. 2nd transducer receives 4. If for some reason the signal fails to arrive at the receiving transducers, the failure is detected automatically and an error flag is generated to alert the user. Signal quality in cavity assessed 5. The frequency of the ultrasonic signal is constantly adjusted so the sensor maintains resonance in varying operating environments. Ultrasound properties selected Hz The sensor inherently compensates for changes in the air s temperature, pressure or humidity. A strong resonating sound wave in a small space provides a large signal that is easy to measure. Acu-Res has a signal to noise ratio more than 40db stronger than other ultrasonic technologies.
