Diffuser element and housing are carefully designed for accurate cosine response. Silicon photo
diode provides good match to solar spectrum. Two-piece housing minimizes radiation heating,
allows convection cooling of the sensor, and prevents the trapping of water or dust.

8.5.1 Installing the Sensor
Spring-loaded mounting screws, in conjunction with the level indicator, enable rapid and
accurate leveling of the sensor. The Solar Radiation sensor is designed to be mounted on the
Sensor Mounting Shelf (Davis Instruments Product Number 6672). The Sensor Mounting Shelf
is a stand that attaches to your sensor and provides a mounting location for up to two sensors.
For the most accurate readings, clean the diffuser after mounting, and then periodically. Use
ethyl alcohol (NOT rubbing alcohol) or water with a little detergent in it.
