Here is a home made heat shield I made for my Davis WX Stations temperature gauge. This would be a good science project for those students doing weather station projects, or if you want one on your temperature sensor. (Pictures below)
1 - 1/2 inch PVC pipe ( 4 ft. lengths available to purchase at hardware stores )
1 - 1/2 inch PVC tee
1 - 1/2 inch PVC 90' elbow
1 - 1/2 inch PVC union
2 - Hose clamps of special mounting ties
2 - Sets of three plastic cereal bowls from Dollar General or other dollar store. (yes, plastic bowls)
1 - Section of 1/2 inch pipe insulation (brown colored foam type with a split) use it for spacers, cut 5 - 1
PVC cutter or saw
7/8 inch uni-bit or 7/8 inch hole saw and an electric drill.
end, the union is greater than 7/8 inch so the bowl will fit to the union. Allow a 5
minutes to dry.
between and when last bowl is on make sure it will be snug when the 90 elbow is
connected, the foam spacers will press together firmly. Do this before gluing to
assure proper spacing and fit. If you need to cut a small
mount you can do that now so it will be snug.
5. Glue the tee vertical on the end and allow to dry 5 minutes.
mounting ties. Silicone the hole if you used one to insert sensor and at seams as
desired. (You can run the gauge in the pipe or drill a hole in the elbow and seal
with silicone as I did. Keep the pipes open for air flow and the tip of sensor just
out of the end as in picture).
Thats all there is to it, takes about 35 minutes of time to build. My temperature sensor is 6 ft. above the ground mounted on the side of the tower. You can modify your mounting as you see fit for your application.
