SOLAR RADIATION (Global Irradiance) First Class Pyranometers
Radiometer for solar irradiance measurement, according to ISO 9060 and WMO No. 8 (Part I, Chapter 7) standards. These sensors are classified as ISO9060 First Class. With a total daily uncertainty of 5% within 0…180° field of view, flat spectral response (285-3000 nm) and optimal temperature stability, this sensor represents the optimal compromise between cost and quality of irradiance measurement.
• Spectrally flat Class B (First Class) pyranometer. Compliance with IEC 61724-1: 2017
• Electrical insulated (DPA855-980), Galvanic insulated (DPA980)
• Calibration traceability to WRR
• Modbus register for Instant value, Ave/Min/Max values over programmable time base (DPA980)
• 10…30 Vac/dc power supply (DPA855/980)
• Ideal instrument in PV plants performance monitoring and meteorological networks
