Description

The RK200-03 Pyranometer is produced based thermopile principle; sensing elements are made by winding – plated thermopiles with multi contacts.Its surface is coated by black coating with high absorption rate. Hot contacts on the sensors surface, while the cold junction is located within the body,temperature difference between the hot and cold junction generates electromotive force, the thermoelectric effect is proportional to the solar radiation. In order to reduce the ambient temperature effect ,temperature compensation circuit designed here to reduce the effects to products properties.
