Solar radiation sensor

It consists of two parts, the pyranometer and the shading ring. The function of the shading ring is to ensure that the direct radiation of the sun can be continuously blocked from sunrise to sunset. The shading ring is composed of a shading ring, a ruler, a screw adjusting screw, a bracket, and a chassis. The shading ring has a width of 65mm and a diameter of 400mm, which is fixed on the screw adjustment screw of the scale, and the scale is engraved with latitude and declination scales. The ruler and bracket are fixed on the chassis and should be fixed according to the geographic latitude of the shooting site.

Test range: 0～2000W/m2, resolution 1W/㎡, accuracy ±5% Sensitivity: 7～14μV/wm-2 Response time: ≤35 seconds (99%) Internal resistance: about 350Ω Spectral range: 0.3～3μm .Annual stability: ±2% Internal resistance about 350Ω Cosine response: ≤±7% (when the sun altitude angle is 10°) Azimuth response error: ≤5% (when the sun altitude angle is 10°) Working environment temperature: -40℃～ +50°C
