Model SD6 - Digital Sunshine Detector Brochure

The SD6 digital detector is intended to indication of direct sun radiation up from the 120 W/m limit of radiation power striking one area unit.
The measurements are done on the optical principle. The basic part of the sensing unit is a circular shade. There are 16 slots evenly distributed along the shade perimeter. Behind the slots, screened photosensitive elements (photo-diodes) are placed. During the assembly, the sensing unit shall be oriented so that the axis of the shade runs parallel to the rotation axis of the Earth. The orientation of the sensing unit, evenly distributed photodiodes, and a suitable size of slots in the shade ensure that solar and sky radiation is absorbed at any position of the Sun.
