This variant of the WindObserver has been designed to remain ice
free in most freezing weather conditions. With exceptionally high
heating power and the ability to measure wind speeds up to 75 m/s
(0-168mph) the instrument is ideal for use in extreme conditions
where performance and high reliability are paramount.
With 150 Watts of electrical heating producing 1 Watt/cm²,
and tested in accordance with MILSTD810F, the unit is particularly
suited to operate as part of wind turbine control systems which
are exposed to extreme weather conditions. Manufactured from stainless
steel with no moving parts, this WindObserver is ideal for replacing
mechanical anemometers, which require regular maintenance and calibration
reducing down time and maintenance costs.
The instrument gives an output status indicating the validity of
data, so that you can be confident that the instrument is providing
true data rather than false data. The Windows™ based WindCom
communications package allows the user to configure the anemometer
in various modes from a PC. Communication in operation is via RS422/RS485
bidirectional link, which allows several units to be networked together
and data logged on demand.
Experience gained in the field has been translated into laboratory
conditions where the instrument has been rigorously tested against
internationally recognised standards and meets the stringent performance
criteria specified by wind turbine manufacturers, airports, marine,
oil and gas production, and meteorological organisations around
the world.
