PYRANOMETER AND METHOD OF DETECTING A SOILING ON A DOME IN A PYRANOMETER

The present invention relates to a pyranometer and to a method of detecting a soiling on a dome 1 in a pyranometer 100. According to an aspect, the pyranometer 100 comprises a dome 1 enclosing a cavity 10, at least one light emitting source5 arranged such that a light exterior to the dome 1 does not...

Zusammenfassung:The present invention relates to a pyranometer and to a method of detecting a soiling on a dome 1 in a pyranometer 100. According to an aspect, the pyranometer 100 comprises a dome 1 enclosing a cavity 10, at least one light emitting source5 arranged such that a light exterior to the dome 1 does not directly impinge on the at least one light emitting source, a diffusor 4; wherein the at least one light emitting source 5 is configured to emit a light substantially directed to a portion of the diffusor 4, and wherein the diffusor 4 is configured to diffuse the light emitted from the at least one light emitting source 5 on the dome 1; and one or more first light detecting sensors 6a arranged in the cavity 10 and configured to measure an intensity of the light reflected from the dome 1 and impinging on the one or more first light detecting sensors 6a.
