The Model 240-152 Shadow Band is used with a
pyranometer for measurement of diffuse sky radiation.
The shadow band prevents direct solar radiation from
reaching the pyranometer. If used in conjunction with a
second pyranometer without a shadow band, direct
radiation can be calculated by finding the difference
between the two pyranometer measurements.
The shadow band is ruggedly constructed of black
anodized aluminum, weighs approximately 24 pounds,
and uses a 3" band of approximately 25" diameter to
shade the pyranometer. A platform at the center supports
the pyranometer in a level position. The declination
setting must be adjusted regularly. Engraved markings
for latitude and solar declination make the device easy to
set up. |
