Rotating Shadow Blade PRB-100

PRB-100 Rotating Shadow Blade is designed to shade the pyranometer from the direct sun for the measurement of the Diffused Horizontal Irradiance (DHI).
Shadow blade is tilted based on the latitude of the installation site, and the intermittent movement of the blade is controled by the built-in CPU and pulse motor.
By this feature, PRB-100 can measure both Global Horizontal Irradiance (GHI) and Diffuse Horizontal Irradiance (DHI).
Based on the configuration, unit can be dedicated only for DHI.
