Solar energy is a significant
element in large-scale atmospheric
motion, and as a
result, it has an important
place in meteorology. It is
directly related to atmospheric
stability, and is used in
determining stability classes
for pollution studies. Met One
Instruments supplies solar
sensors to meet virtually any
monitoring requirement.
Model 095 Pyranometer
The Model 095 Pyranometer
incorporates a multi-junction
differential thermopile and a
precision ground optical glass
hemisphere which is transparent
to wavelengths 0.285
to 2.80 microns. It is used for
high precision, broad bandwidth
measurements of incident
solar radiation.
Features
n Differential thermopile
detector
n High accuracy, broad
bandwidth
n Temperature compensated
n Rapid response time
n Built-in leveling devices
The detector element is of
wirebound-plated construction
with black and white segments.
When exposed to
solar radiation, the differing
absorptivity of the black and
white surfaces develops a
temperature differential. The
thermopile then produces a
voltage proportional to the
solar radiation. Built-in thermistor
circuitry is incorporated
to eliminate the effects of
ambient temperatur

The single hemispherical
optical glass dome has a
waterproof seal, but can easily
be removed for repairs.
The case is cast aluminum,
painted white, and is fitted
with a desiccator, circular
level, and leveling screws. A
mounting base with a vertical
3/ 4� IPS pipe simplifies field
installation of the sensor. This
rugged instrument is capable
of withstanding mechanical
vibrations of up to 20 G’ s.
