Turbine Control Wind Sensors

Chapter 90 covers a wide variety of instruments and apparatus which are, as a rule, characterised by their high finish and high precision. Most of them are used mainly for scientific purposes (laboratory research work, analysis, astronomy, ect.) for specialised or industrial purposes (measuring or checking, observation, ect.) or for medical purposes. The Chapter includes in particular, instruments and apparatus designed for certain specifically defined uses ( surveying, meteorology, drawing, calculating, ect.). The turbine control wind sensors model numbers: FT702LT-V22-FF, FT702LT-V22-PM, FT702LT/D-V22-FF, FT702LT/D-V22-PM are instruments that record wind speed and directions. As such, they meet the terms of heading 90.15 which specifically provides for meteorological instruments and appliances. Anemometers and other instruments for measuring wind direction at the tariff item level.
