PELENG SF-12-21 Actinometer
PELENG SF-12-21 Actinometer
PURPOSE
  • Direct solar irradiance measurement in 0.3 μm to 10 μm range
  • Operating principle of the device is based on the conversion of manganin- constantan thermoelements of irradiance generated by solar irradiation in electric signal in analog form. Further, the signal enters on the input of the electronic unit, is converted into digital form, processed by the built-in microcontroller and displayed on the led indicator of the electronic unit.
  • Actinometers consist of converter and electronic unit. Electronic unit can be connected to PC via interface RS-485. During operation, the values ​​of direct solar radiation irradiance are displayed in the “Peleng Meteo Actinometry” software in the display window of the sensor operation, or can be calculated from instantaneous values, taking into account the conversion factor.
Available device versions
  • actinometer with analog output signal
  • electronic actinometer with digital and analog signals
