The SP-110 is a low cost yet highly accurate self-powered sensor with a millivolt output and exhibits excellent cosine response. The SP-110 is the first choice sensor for scientists who want to measure global solar radiation.
The SP-110 incorporates a silicon-cell photo-diode 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 Teaching and Research Applications
Apogee Instruments SP series pyranometers consist of a cast acrylic diffuser (filter), photodiode, and signal processing circuitry mounted in an anodised aluminium housing, and a cable to connect the sensor to a measurement device.
Sensors are potted solid with no internal air space and are designed for continuous total shortwave radiation measurement on a planar surface in outdoor environments. SP series sensors output an analogue voltage that is directly proportional to total shortwave radiation from the sun.
The voltage signal from the sensor is directly proportional to radiation incident on a planar surface (does not have to be horizontal), where the radiation from all angles of a hemisphere.
