This pyrheliometer measures the intensity of a radiant beam at normal incidence that comes only from the solar disk which includes about 5° of circumsolar radiation. The sensor of this instrument, designed in conformity with WMO specifications, is mounted on a tracking system to be always directed to the sun. The tracking system incorporates a sun sensor for tracking during clear weather, and changes automatically to a mechanical mode during cloudy weather.
