New Gill WindObserver FC

Wittich & Visser presents the new Gill WindObserver FC, the 75 m/s heated ultrasonic wind speed and direction sensor for higher wind speed applications.

The WindObserver FC is the new first class heated anemometer that provides wind speed and direction data up to 75 m/s. The WindObserver FC is specifically designed to measure wind speeds up to 75 m/s with a high degree of accuracy. The elimination of moving parts, together with a rugged stainless steel construction means that the WindObserver FC is virtually maintenance free and requires no calibration on site.

The small opposing transducers provide maximum possible directional ultrasonic signals, used to provide wind data, whilst ensuring the minimum possible flow distortion across the speed range. For high wind speed applications and in poor weather conditions the four transducers system is more robust than three transducer systems. The unique heating system provides up to 72 W per transducer to ensure best possible performance in icing conditions.

The flexible design ensures that the WindObserver FC can be configured by the user to their exact requirements, which include 1, 2 or 4 Hz ouputs and heating. Communication is via an RS422 bidirectional link, which allows data to be logged on demand. The first class WindObserver FC has been rigourously tested to internationally recognised standards and meets the stringent performance criteria specified by airport, offshore, meteorological and environmental applications.
