due to humid environments, the EC150 is provided with window wicks that
draw moisture away from the measurement path and are easily replaceable
during routine maintenance.
•
Unique design contains little obstruction surrounding the sample
volume
•
5 W total power consumption
•
Synchronously samples data from the EC150 and CSAT3A
•
Automatically configured via a Campbell Scientific datalogger
•
Minimal spatial displacement between sample volume and CSAT3A
•
Slim housings located away from the measurement volume to
minimize body heating effects due to solar radiation
•
Symmetrical design for improved flux measurements without a bias
for updrafts and downdrafts
•
Slanted windows to prevent water from pooling and blocking the
optical path
•
Scratch-resistant windows for easy cleaning
•
Hydrophobic coating on windows to repel water, dust and pollen and
to prolong time between window cleaning
•
Equipped with internal window heaters to keep the windows surfaces
free from condensation and frost – especially beneficial in humid
environments or conditions with frequent frost formation
•
Optical layout that is not affected by solar interference
•
Mercury cadmium telluride (MCT) detector for low-noise
measurements and long-term stability of factory calibration
•
Chopper housing without thermal control results in significantly
reduced power consumption
•
Any CSAT3A with serial numbers of 2000 or greater have an updated
design with more rigid geometry for improved sonic-temperature
accuracy and stability, and with a more stream-lined, aerodynamic
mounting block
4.3 Gas Head Memory
The EC100 electronics (see Section
(p. 4)
) are
universal for the entire Campbell Scientific family of gas analyzer heads. In
addition to the EC150 gas analyzer head, the IRGASON or EC155 gas
analyzer head can be connected to the EC100 electronics (one gas analyzer
head per EC100). All sensor heads have dedicated, non-volatile memory,
which stores all calibration, configuration, and setting information. The EC100
electronics can be mated with any of these gas analyzers or an optional
CSAT3A sonic anemometer head.
4.4 Self-diagnostics and Data Integrity
EC100 electronics provide an extensive set of diagnostic tools which include
warning flags, status LEDs, and signal strength outputs to identify instrument
malfunctions and warn the user of compromised data. These flags are further
(p. 37)
. The flags also prompt the
user when the instrument needs servicing and can facilitate troubleshooting in
the field. The EC150 outputs the optical strength of signals, which can be used
to filter data when the path of the instrument is obstructed due to precipitation
or dirty windows.
