Pyranometers
Back to the Irradiance Sensors Section
The Thermopile Pyranometer is part of the SEVEN meteorological sensors range, which includes professional and intelligent measuring sensors with a digital interface for environmental and industrial applications such as PV plants.
It is designed to accurately measure the Global Horizontal Irradiance. The measured irradiance is transmitted to the data loggers and receiver units via a 2-wire RS485 bus with Modbus RTU protocol. SEVEN offer 3 models pf Thermopile Pyranometers; Class A, Class B, and Class C as per ISO 9060: 2018
