Re: Davis Radiation shield
Some people have made their own shields - a search on the forum should find it.

Re: Davis Radiation shield
As I don't know what the sensor is like in that WS then I can't say if it'll fit in the Davis shield but, here's a couple of sites with home made designs that may prove useful:

Morelo
Does your transmitter not come with the plastic weather shield as supplied on the wh1081?
I just mount my transmitter up under the eaves of the house where it never gets any sun, and is exposed to some wind but not rain. I haven't had any reason to use any other weather shield than the one supplied.
If you didn't receive a weather shield with your unit then I can send you a photo of what it should look like?
Maybe these WH108x units vary around the world.

Re: Davis Radiation shield
Ahh ofcourse ive got his own shield,but isnt that good in order to give me correct clues,because of the sun that sees it during the most of the day time....so i get mm 2-4 degrees higher T than my citys davis station....that's why im asking about davis shield ....
Re: Davis Radiation shield
2 - 4 degrees is not very much variation. How far away is the other station? Is it out in the clear like yours? Is it at the same elevation?
Have you tried checking the temp at your station location with a different themometer?
It gets pretty hot here... and I have a 24hr FARS... and it does make a difference, but comparing my station to the next closest weather station is not a very good indication if I am on or or not.

Re: Davis Radiation shield
BTW.. the shield you are looking at is not very big, espcially inside.
The shield is designed to hold the small sendor itself, which is about 2"x2" square and with the components less than an inch thick. It suspends the sensor in a slot.
the sensor has both temp and humidity in it and is cabled to reach the ISS board.
I have a picture of one as I replaced one on my station once.

Re: Davis Radiation shield
This is what the sensor that is inside the shield looks like. At the most the card is about 2 inches long.

Re: Davis Radiation shield
Yes the other station is located in the center of the town mm about 5-8m higher than mine station,i get almost the same clues during the night(or a bit lower cuz actually i live in the suburbs of city)......ah so you think i will not be able to put my sensor in there?Is the hole that small? ...
davis shield inside i saw that and i thought i would prolly be able to put my sensor in there..it looks deep enough for my sensor,doesnt it??

Would this mini Stevenson Screen be of any use?

Re: Davis Radiation shield
Screwfix do a nice 220mmx220mm white plastic louvre as a gas vent. I've been thinking of making one based on these for the sides. They are only about £1.20p each so if you wanted a larger one you could use more. Would be easier and cheaper.
