Aspirated Radiation Shield

43502

The Aspirated Radiation Shield provides accurate ambient air
temperature measurements in a unique low cost, small size,
and conservatively rated instrument. Radiation errors are less
than 0.2° C RMS with the shield exposed to solar radiation of
1000 W/m2. The triple wall shield employs three concentric
downward facing intake tubes and a canopy shade to isolate
the temperature sensor from direct and indirect radiation. The
temperature sensor mounts vertically in the center of the intake
tubes.
The small shield size reduces the surface area exposed to
incoming radiation during the day, significantly reducing the
amount of heat that needs to be washed away from the intake
tubes.
