The Solar Radiation Sensor provided by us measures global radiation, the sum at the point of measurement of both the direct and diffuse components of solar irradiance. The Solar Radiation Sensor provided by us has a transducer which converts incident radiation to electrical current and is a silicon photodiode with wide spectral response. Solar Radiation Sensor also integrates the irradiance values and displays total incident energy over a set period of time. The outer shell shields the sensor body from thermal radiation and provides an airflow path for convection cooling of the body, minimizing heating of the sensor interior. It includes a cutoff ring for cosine response, a level indicator, and fins to aid in aligning the sensor with the sun’s rays. The space between the shield and the body also provides a runoff path for water, greatly reducing the possibility of rain or irrigation-water entrapment. The diffuser is welded to the body for a weather-tight seal; it provides an excellent cosine response. The transducer is a hermetically-sealed silicon photodiode with integrated amplifier. Spring-loaded mounting screws, in conjunction with the level indicator, enable rapid and accurate leveling of the sensor. Each Solar Radiation Sensor is calibrated against a secondary standard Pyranometer in natural daylight.
