LP PYRA 08, LP PYRA 08AC, LP PYRA 08AV – Piranometers

Delta Ohm manufactures, according to ISO 9060 and the recommendations of
the WMO, the range of 2nd class pyranometers LP PYRA 08. These instruments
are robust and reliable, provided to withstand adverse climatic conditions and
suitable for installation in the field.
The pyranometer LP PYRA 08 measures the radiation on a flat surface (Watt/
m2). The radiation measured is the sum of direct solar irradiance and diffuse
irradiance (global radiation).
The sensors have mV output and do not need to be powered, their typical
sensitivity is 10 mV/(kW/m2). The pyranometers are also available with an
amplified and converted 4…20mA current or 0…10Vdc voltage signal.

Product Description

Delta Ohm manufactures, according to ISO 9060 and the recommendations of
the WMO, the range of 2nd class pyranometers LP PYRA 08. These instruments
are robust and reliable, provided to withstand adverse climatic conditions and
suitable for installation in the field.
The pyranometer LP PYRA 08 measures the radiation on a flat surface (Watt/
m2). The radiation measured is the sum of direct solar irradiance and diffuse
irradiance (global radiation).
The sensors have mV output and do not need to be powered, their typical
sensitivity is 10 mV/(kW/m2). The pyranometers are also available with an
amplified and converted 4…20mA current or 0…10Vdc voltage signal.
Each pyranometer is calibrated individually with reference to the WWR (World
Radiometric Reference in Davos CH) and accompanied by calibration report.
Thanks to a new sensor LP PYRA 08 has a response time of less than 8 seconds
and is used when it is necessary to record changes in short and very short-term
irradiation.
