Anemometer Attack /

Post by Paul C » Sun Aug 23, 2015 9:37 am

At 0430hrs on the 22nd August my wind speed stopped recording. On further investigation I have discovered that the cable leading to the wireless transmitter unit appear to have been bitten off in two places. The cable has been there for approx 10 years and never had any trouble before.

Does anyone know if just the cable can be replaced, or is it a new anemometer. I may try and splice the cable back together first but I am guessing this may not provide a satisfactory connection. Leading to a lost of data

Bugger!
Might be rats.
I think a new anemometer might be the best option in the long run - splicing the wires together might work for a while but moisture
will eventually get in.

Hi Paul,

About 10 years ago now, our new Labrador pup chewed through both the TV aerial co-axial cable and the satellite dish cable outside and I repaired both and then wrapped self-amalgamating tape tightly round the join (you have to stretch it to about twice its original length and then it bonds to itself) and both cables are still working fine. So it should be fine to join each core of the cable (use a bit of heatshrink sleeving round each soldered join) and then wrap the whole join with self-amalgamating tape. Both heat-shrink sleeving and self-amalgamating tape can probably be obtained at Maplin's emporium in Carlisle.

I have spliced lots of outdoor sensor cables for the various weather stations I have built and not had any problems at all. It has got toe be worth a try.
If not I do have a Davis anemometer lying around unused if its of any use. It does work last time I tried it.

Cheers everyone - rats !! - do you think so, not in "Brampton"

Will try splicing etc - got to go in Carlisle tomorrow so will call in at Maplins - tks

Mike - thanks re offer of anemometer - will let you know how I get on


I am also thinking of moving my VP2 - moving sensor into Met office screen and re-siting auto rain gauge - anyone else tried this as yet.

OK - repairs carried out and appears to be working, fingers crossed it holds and is water tight, may add a few more laters of tape tomorrow

Highly recommend self amalgamating tape to everyone.

Glad you got some tape Paul and that it worked OK. Secret is to stretch it really well, almost to breaking point and then the whole joint becomes completely sealed and you have to cut through the stuff if you ever want to get into it again! Also use it on the plugs on satellite dishes etc as it seals those too from the weather and doesn't degrade with sunlight etc. You really only need maybe two layers of the stuff as long as you go an inch or so on to the good bit of cable either side of the join.

Deer or rabbits in my experience, though I wouldn't rule out a dog or the local drunk coming home and finding the chippy closed...

Chicken wire wrapped around it in future may help.

I think the ''...local drunk..'' seems about right, lot round Brampton I've heard.

LOL !!

If anyone knew where my station was exactly they could rule out the roaming drunk suggestion, even my two "mature" sons woulndt even make it, drunk or otherwise :lol:

Deer - never seen any near me, nearest at least a mile
Fox - again, never seen
Rats - did have some 6 months ago but all killed
Dog - area fenced off
Rabbits - in nearby field so possible
Person - would like to think not, unlikley given height about ground where damage occurred.
Crows - they do have a go at the sunshine recorder paper every now and again
