Hi Folks,
The last couple of days I notice I do not receive wind speed data on my WH1081.
I get all other data (wind direction, temp, rain etc)
I just changed the batteries and reset the connectors in the transmitter but still the same.
Any ideas?
Cheers....

Re: Got Wind direction but no wind speed
Hi,
Have you checked if the anemometer is rotating?
If not, the solution should be obvious. If it is, then there couald be a fault anywhere in the cable or in the anemometer or in the transmitter. If you have a multimeter then testing should be fairly easy, otherwise the (magnetic reed in) the anemometer is the most likely fault, or a seized bearing, and either can be replaced for around £1. But with replacement anemometers available from Maplin for £2.50, it's not normally worth bothering.
Cheers, Alan.

Re: Got Wind direction but no wind speed
Alan (AllyCat) has given you a full answer, but see also his viewtopic.php?f=13&Amp;t=13046&Amp;p=102176 about how the bearing is better protected in newer models.
My WH1081 was bought in 2010, I bought a replacement anemometer online in 2014 (Maplin item code N76NF), but the reed failed after 2 years and so I replaced that (I found it a bit tricky) with a Assemtech Micro Reed Switch N/O (Code: CL37S) from a Maplin store. Stevenage have it in stock for £2.29, but as Alan suggests you could probably find a cheaper source, perhaps a different make.
There are 3 compatible replacement anemometers (EDIT 2 - ignore their conflicting answers suggesting each is compatible with only 1 model) each available at £2.49 to be ordered in Maplin for 3 day delivery:

- (Code: N76NF) with a long wire intended for those models where it needs to plug directly into transmitter and grey cups. Your current anemometer will plug into wind vane. If you put this in place of your old one you will end up with lots of wire that has to be put somewhere, or (like me) you could move the anemometer higher up away from the vane.
- (code: N82NF) with a short wire and white cups for mounting on your existing wind sensor arm
- (code: N09QR) with a short wire and grey cups for mounting on your existing wind sensor arm (Darker coloured cups absorb more sun and are less likely to freeze).

Re: Got Wind direction but no wind speed
Thanks for the replies.
I think a visit to Maplin is in order.
Cheer, Alan

Re: Got Wind direction but no wind speed
A new anemometer from Maplin did the trick.
Thanks for your guidance guys.
Cheers, Alan
