Overview
Enviro Test Construct solar measuring radiation sensor pyranometer is produced based on 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.
