We began selling to the wind turbine industry in 2002, and have worked closely with the top wind turbine manufacturers ever since to refine and improve our sensors. With over 70% of all offshore wind turbines using an FT sensor, we are the undisputed market leader in this sector.
FT wind sensors have no moving parts and do not need re-calibration. This reduces costly turbine down-time and maintenance visits. They are well suited to offshore applications with the incorporation of enhanced protection to prevent corrosion from high levels of salt spray. They have achieved a Class C5-M rating as recommended by the GL Renewables Guidelines for the Certification of Offshore Wind Turbines 2012 (Section 7.11.4).
For operation in ice-prone areas both onshore and offshore, the FT7 Series is fitted with a highly effective thermostatically controlled heating system. A three element heater (one element located in the top of the sensor and two in the bottom) helps to keep the sensor ice-free. The sensor has passed the demanding US military icing test MIL-STD-810G.
Further independent tests to recognised standards show that our sensors can withstand random and sinusoidal vibration, physical impact, lightning and EMC. The sensors have also passed a hail test with 50mm hailstones hitting it at 30m/s.
FT7 Series sensors can be supplied with an analogue or digital interface. They can be mounted either flat to a bar or, with the specially designed adapter, to a pipe. Both systems allow for quick and repeatable alignment of the sensor.
