I see my anemometer is locked up again (not turning) in 30km winds this am, so I guess it's time to plan another adventure up the tower and pull the assembly down once again. Luckily I do have a spare anemometer from my original VP I can install while the newer one is repaired. Not a task I look forward to!
This unit has failed every year I have had it installed. New bearing kit fixes it for the year, then when it gets cold out once again it ceases up. Is there an improved version of this anemometer unit? The old VP design has last for many years...
We do get a lot of wind here, often in the 50-70KPH + range for days sometimes, and in the winter it gets into the -40 range (not considering windchill!) Maybe these bearings just wear out?
