LP02 is a solar radiation sensor that can be
applied for most common solar radiation
observations. It complies with the latest ISO and
WMO standards. The scientific name of this
instrument is pyranometer. LP02 is a modern
alternative for the so-called “star” or “black and
white” pyranometers overcoming the problem of
poor stability of the white reflective paint.
LP02 serves to measure the solar radiation flux
that is incident on a plane surface in W/m2 from a
180 degrees field of view (also called “global”
solar radiation). Working completely passive,
using a thermopile sensor, LP02 generates a
small output voltage proportional to this flux.
Contrary to photodiode-based- and “black and
white” instruments LP02 has a spectrally flat
response across the full solar spectrum.
Using LP02 is easy. For readout one only needs
an accurate voltmeter that works in the millivolt
range. To calculate the radiation level the voltage
must be divided by the sensitivity; a constant
that is supplied with each individual instrument.
LP02 can directly be connected to most
commonly used datalogging systems.
LP02 can be used for general meteorological
observations, building physics, climate- and solar
collector testing. A common application is for
outdoor solar radiation measurements as part of
a meteorological station. This application requires
horizontal levelling; levelling feet (7) and a level
(11) are included. The LP02 cable can easily be
installed or replaced by the user.
Applicable standards are ISO 9060 and 9847,
WMO (World Meteorological Organisation), and
ASTM E824-94. LP02 can also be used for
stability estimations according to EPA ( EPA-
454/R-99-005).
