FT Technologies Wind Sensor FT702LT-V20
Description
The FT702LT incorporates FT Technologies’ patented Acoustic Resonance sensing technology. This proven award-winning technology uses an acoustic (ultrasonic) signal which is resonated inside a small cavity to measure both wind speed and wind direction.

High Reliability
Each aspect of the FT702LT design has been optimised for the demanding environment in which modern megawatt scale turbines are installed. Rigorous testing at the design stage, including advanced highly accelerated testing techniques such as HALT, means that the FT702LT can be trusted in the most demanding conditions. All production sensors are 100% wind tunnel tested and undergo powered burn-in testing to ensure that the highest levels of reliability are achieved in the field.
Anti-Icing Heater
For operation in ice-prone areas, the FT702LT is fitted with a highly effective thermostatically controlled ‘all-body’ heating system. A three element heater (one element located in the top of the sensor and two in the bottom) is used to ensure that the heating is evenly distributed over the entire surface area. The heat flux exceeds the Finnish Met. Institute guidelines of 0.4W/sq. cm.
Easy Alignment
Mounting and aligning the sensor on the turbine is very straightforward. A machined flat on the sensor body defines the 0deg wind datum so that the sensor automatically aligns with the turbine axis.
