SR11 is a solar radiation sensor that can be
applied in scientific grade solar radiation
observations. It complies with the “first class”
specifications within the latest ISO and WMO
standards. The scientific name of this instrument
is pyranometer.
SR11 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, SR11 generates a
small output voltage proportional to this flux.
Employing two glass domes, certain
measurement errors are reduced; in particular
thermal offsets, so that a high measurement
accuracy can be attained.
Using SR11 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.
SR11 can directly be connected to most
commonly used datalogging systems.
SR11 can be used for scientific 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 SR11 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. SR11 can also be used for
stability estimations according to EPA ( EPA-
454/R-99-005).

measurements.
