Overview
The LI200X, manufactured by LI-COR, is a pyranometer that monitors sun plus sky radiation. It connects directly to our data loggers, and is used extensively in solar, agricultural, and meteorological applications.
Key Advantages
Connects directly to most Campbell dataloggers
Technical Description
The LI200X uses a silicon photovoltaic detector mounted in a cosine-corrected head to provide solar radiation measurements. Calibrated against an Eppley precision spectral pyranometer (PSP), the LI200X accurately measures sun plus sky radiation for the spectral range of 400 to 1100 nm. Sensors calibrated to this spectral range should not be used under vegetation or artificial lights.
The LI200X includes an epoxy-encased completion circuit in its cable. This completion circuit standardizes the sensor's sensor's calibration, allowing individual sensors to be interchanged without altering multiplier and offset values.
The standard output is 0.005 mV per W m-2, which provides a signal of 5 mV in full sunlight (1000 W m-2). All of our data loggers, except the CR200(X) series, can measure this output.
