RADIATION MEASUREMENT : PYRANOMETER)
Solar Radiation sensor COMPLIANT
WITH ISO and WMO STANDARDS
SLP02 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. SLP02 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.

SLP02 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, SLP02 generates a small output voltage
proportional to this flux. Contrary to photodiode-based- and “black and white”
instruments SLP02 has a spectrally flat response across the full solar
Using SLP02 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. SLP02 can directly be connected to
most commonly used datalogging systems.
SLP02 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 SLP02 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. SLP02 can also be used
for stability estimations according to EPA ( EPA-454/R-99-005).
