The SP-215 is an amplified sensor with a 0-5 volt output and exhibits excellent cosine response. All Apogee pyranometers incorporate a silicon-cell photodiode that measures total shortwave radiation with a sensor housing design that features a fully potted, domed-shaped head making the sensor fully weatherproof and self-cleaning. Total shortwave radiation is an important component in determining […]
The SP-215 is an amplified sensor with a 0-5 volt output and exhibits excellent cosine response. All Apogee pyranometers incorporate a silicon-cell photodiode that measures total shortwave radiation with a sensor housing design that features a fully potted, domed-shaped head making the sensor fully weatherproof and self-cleaning. Total shortwave radiation is an important component in determining evapo-transipration rates, energy balance, net radiation as well as monitoring solar power panels.
