WebJul 17, 2024 · 3. Pyrheliometer. A pyrheliometer works similarly to a pyranometer and only measures direct beam solar irradiance. Therefore, they are only occasionally used in pyranometer applications. This instrument is also used to track solar systems and ensure that the entire solar system is aimed toward the sun all the time. WebThe pyrheliometer measures the perpendicular solar radiation coming directly from the sun and a small part of the radiation coming from the sky around the sun. Usually, sunlight enters this device through a glass window in a thermocouple (a …
