Collection: Silicon pyranometer
The pyranometer (global radiation sensor) is used to measure global radiation.
Global radiation is the direct solar radiation falling on the Earth from the upper hemisphere and the indirect diffuse sky radiation. It covers a spectral range from approximately 200 to over 3000 nm, i.e., from the UV through the visible to the far infrared range.
Global radiation can be measured using detectors with blackened thermocouples, among other devices. Such precision measuring devices are usually very expensive, deliver mV signals, and require external amplifiers.
For this reason, the use of pyranometers with adapted photodiodes as detectors is recommended for many applications, e.g., in the agricultural or solar sectors. The detected spectral range is between approximately 350 and 1100 nm, i.e., over 90% of global radiation.
Pyranometers with Si photodiodes are calibrated with a precision pyranometer under approximate global radiation conditions. Thus, the measurement results are very comparable.
The pyranometers are optimized for use with data loggers and control systems.
