fitted with a reference lamp.
5. WIND SPEED
These wind speed rotors are initially calibrated in a wind tunnel by comparison with a standard
reference rotor calibrated to national standards (NPL).
As long as the physical shape or form of these calibrated parts does not change, (i.e. by physical
damage to the rotor) then the sensor calibration does not change to any measurable degree as l
ong as the bearings are allowing free movement. A bearing check is recommended annually, with a
bearing change recommended at a minimum of every 2-3 years.
6. WIND DIRECTION
The position of the wind vane relative to the electrical potentiometer inside is calibrated and fixed at
the time of manufacture.
As long as the physical shape or form of the wind vane and its spindle does not change (i.e. by
physical damage), then the sensor calibration does not change to any measurable degree as long
as the bearings are allowing free movement. A bearing check is recommended annually, with a
bearing change recommended at a minimum of every 2-3 years.
7. BAROMETER
Recalibration is recommended annually. Sensors can be returned to Skye or can be checked by a
direct comparison against a reference.
8. RAINGAUGE
The raingauge top should be kept free of debris at all times. In dusty environments it may be
necessary to clean the funnel filter regularly.
These gauges can be easily recalibrated by adding an exact volume of water. Full instructions are
given in the sensor manual.
