I’ve been dealing with a frustrating issue with our B&G WS320 wireless wind instrument. The unit is only 3 years old, but it’s only worked the first 1.5 years. In 20 knots of wind it would read 2-3 knots when it “worked” and 0 when it didn’t. The frustrating part was when I took the instrument off the mast and blew on the cups, it would read higher numbers (10-15 knots). It never lost connectivity, and the wind direction always worked, but the apparent wind speed was never accurate. I replaced the bearing cartridge and battery, climbed the mast at least a dozen times, and pulled the unit apart a few times trying to figure out what the problem was.
I think I finally found the issue. The top cover of the circuit board housing was not tight.

I think this allowed water to pool around the wind speed sensor on the circuit board which ended up shorting out a few components. (top is the new board)


I ordered a replacement circuit board from https://trionics.com/. Hopefully today will be the last trip up the mast. I wasn’t able to find any other accounts of an issue like this with my Google searches, so hopefully this will help others if they end up in the same situation.
