Irradiance Sensor Our Reliable Device for Irradiance Data Measurement Irradiance Sensor Features ■ Solar irradiance measurement with temperature compensation Extended measuring range up to 1200 W/m² Single calibration to standard measuring signal Module temperature measurement Easy mounting 3m connection cable (UV resistant)

Technical Data The short-circuit current of a silicon cell is proportional to the solar irradiance. Si-12TC sensors use a mono-crystalline solar cell (Schott Solar) operated in short circuit via low resistance. All sensors are equipped with active temperature compensation, thus improving measuring accuracy. A special temperature sensor is laminated to the rear side of the solar cell. Each single sensor is calibrated against a pyranometer, which by itself is regularly calibrated by PTB Braunschweig, the German national metrology institute. Mechanical Structure The solar cell is embedded in Ethylen-Vinyl-Acetat...
