First class pyranometer SR15 series

ISO 9060

SR15 pyranometer series is a first class range of solar radiation sensors applied in general high-accuracy observations. The sensor measures the solar radiation received by a plane surface from a 180 ° field of view angle. This quantity, expressed in W/m2 , is called “hemispherical” solar radiation. SR15 pyranometer can be employed outdoors under the sun, as well as indoors with lamp-based solar simulators. Its ori­­entation depends on the application and may be horizontal, tilted (for plane of array radiation) or inverted (for reflected radiation). SR15 pyranometer series is “first class” according to the WMO guide and ISO 9060:1990 standard and “Spectrally Flat Class B” in the 2018 revision. Version SR15-D1 and SR15-A1, equipped with on-board heaters, are compliant in their standard configuration with the requirements for “Class B” PV monitoring systems of the IEC 61724-1:2017 standard. Suggested use - PV system performance monitoring - general solar resource monitoring - indoor simulated solar testing - meteorological networks Your benefits - best measurement accuracy in first class - improved response time - with SR15-D1’s and SR15-A1's on-board heater: compliant with IEC 61724-1 Class B - on-board calibration history SR15 first class pyranometer employs a thermal sensor with black coating, two glass domes and an anodised aluminium body. The digital sensor models offer output via Modbus RTU over 2-wire RS-485 (version SR15-D1) and via Modbus TTL and 4-20 mA current loop (version SR15-D2A2). The analogue version (SR05-A1) offers millivolt output. Several options are available for easy mounting on any platform, in plane of array too.
