Description
Solar Radiation Sensor
The SX2595 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.
