PELENG SF-06-21 Pyranometer

Total solar irradiance measurement in 0.28 μm to 4 μm range
Operating principle of the device is based on the temperature variation determination of manganin- constantan elements of thermobattery, proportional irradiance generated by solar irradiation. Temperature variation transforms into electric signal in analog form. Digital signal in ASCII codes is used via the RS-485 interface according to the corresponding protocols. When working with a computer, the value of the irradiance is displayed in the software window "Peleng Meteo Actinometry”
Two device versions are available:
- pyranometer with analog output signal
- electronic pyranometer with digital and analog signals
