MAINTENANCE
Wind sensors experience vibration due to high velocity wind. The vibration can loosen the mounting
screws or the support structure. Regular inspection of the mounting hardware is required to prevent
damage to the sensor.
10.1
General Inspection
CAUTION:
On occasion a sensor may be damaged by high wind or by a large bird landing on the wind
vane. Before approaching the weather station, check whether the wind vane is in position on the top
of the sensor. If it appears to be out of position, exercise extreme caution when working near the
station because the vane could detach and fall.
1.
Tighten the mounting screws at the base of the sensor if necessary (do not over-tighten).
2.
Spin the anemometer cup assembly. It should turn freely.
3.
Rotate the wind vane gently. It should turn freely with no "rough" spots.
4.
Inspect the counterweight to ensure it is firmly cemented to the vane. Repair if necessary.
5.
Inspect the wind vane to ensure the tail is vertical and the screws holding it to the vane are snug.
6.
Inspect the cable and secure it to the mast to prevent damage due to wind whipping.
10.2
Lubrication and Adjustment
The bearings in the 200-WS-02 sensor may eventually require lubrication to restore free movement of
the anemometer cup assembly or the wind vane. Some disassembly is required to access the bearings,
so it is best to dismount the sensor before servicing. Use a light machine oil (such as fishing reel oil) for
lubrication.
Do not use WD-40 or similar products, as they wear off quickly, leaving the bearing dry and
susceptible to rust.
Disassembly
1.
Remove the sensor from the weather station and take it to a
clean workbench.
2.
Loosen the set screw that holds the vane to the
potentiometer shaft. The set screw requires a 1/16" Allen
wrench.
3.
Lift the tail assembly straight up carefully. The shaft of the
potentiometer will be exposed, and the top of the bearing in
the cup assembly will be visible.
4.
Wipe off any dust that has accumulated.
