West Castle Alpine Monitoring System
The CMP3 pyranometer consists of a thermopile sensor, housing, dome, and prefabricated cable. The thermopile is coated with a black absorbent coating. The paint absorbs the radiation and converts it to heat. The resultant temperature difference is converted to a voltage by a coper-constantan thermopile. The thermopile is encapsulated in the housing in such a way that it has a field of view of 180 degrees and the angular characteristics needed to fulfil the cosine response requirements.
