Scattered radiation sensor

The Scattered radiation sensor is used to measure radiation perpendicular to the Sun's surface and scattered radiation in the narrow circumheliospheric sky around the sun.Scattered radiation sensor consists of two parts: a pyranometer and a light shielding ring. The function of the shading ring is to ensure that direct solar radiation can be continuously blocked from sunrise to sunset. The shading ring is composed of a shading ring, a ruler, a screw adjustment screw, a bracket, and a chassis. The width of the shading ring is 65mm and the diameter is 400mm. It is fixed on the screw adjustment screw of the scale. The scale is engraved with latitude and declination scales. The scale and bracket are fixed on the chassis and should be fixed according to the geographical latitude of the shooting location.
