Protecting sensor circuitry

Post by pns1953 »

OK - after a couple of false starts, I'm now the proud owner of a WH-1080 in the guise of a Watson 8681.
Having read various posts here about the sturdiness (or lack of) of the sensors, I'm wondering what sensible steps I could take to protect them prior to exposing them to the harsh realities :D of life in a Surrey garden.
One obvious step is to give a good coating of silicone grease to the RJ11 plugs and sockets.
I'm wondering whether to take things a step further, and disassemble what I can and spray any PCBs with silicone grease aerosol too.
From the photos posted here it looks as if the bases of the anemometer and wind vane should be removable easily enough to enable access to the boards with the reed switches.
I'm wondering whether it would also be worth it to disassemble the transmitter unit and spray at least the track side of the board, making sure of course to mask the humidity sensor. I could also re-orient the DCF aerial as shown, if required. Of course breaking and entering the unit in this way is probably likely to invalidate any warranty if it was found out.

So - any opinions - am I likely to to make things more reliable by any preventative measures like this, or isn't it worth the risk?

Any thoughts gratefully received ...
Phil

My transmitter unit PCB was already coating with 'something', I've not had the other units apart to check them.
