The SEM228T-A seriesClass A Solar Pyrgeometers is a shortwave total radiation sensor used for solar radiation observation. It is a Class A total radiation sensor conforming to the latest ISO 9060 and WMO technical standards. It measures solar radiation received by a horizontal plane from a solid angle of 2 T steradian degrees (hemispherical), with units of W/m’.
The SEM228T-A series Class A Solar Pyrgeometers operates in a completely passive mode, utilizing a thermopile sensor to generate an output voltage proportional to the incident radiation flux. Due to the use of two spherical glass domes, measurement errors, especially thermal offset, are reduced, resulting in high measurement accuracy.
Application
Used for meteorological observation, building physics, climate, and solar energy harvesting experiments. A common application is as part of a weather station to measure outdoor solar radiation.
