200-1390-90 WindObserver 90
The WindObserver 90 is capable of monitoring extreme high wind speeds up to 90m/s (201mph). WindObserver 90 has an optional heating system and is available with a range of different mounting and connection options for simple installation.
Product Details

The WindObserver 90 has been developed for measuring the highest wind speeds in extreme weather environments such as typhoons and hurricanes and is available with optional heating. The sensor provides data via RS422/RS485 bidirectional link, which allows several units to be networked together and data logged on demand.

With innovative transducer design, this anemometer boasts a very high wind speed range of 0 – 90 m/s (0-201mph) and gives an output status indicating the validity of data, so that you can be confident that the instrument is providing accurate information. With an IP66 rated stainless steel construction, this anemometer meets the stringent performance criteria specified by wind turbine manufacturers, airports, marine, oil and gas production, and meteorological organisations around the world.
