WARNING:
o
Do not carry the EC150 by the arms or the strut between the
arms. Always hold it by the mounting base where the upper and
lower arms connect.
o
Handle the EC150 carefully. The optical source may be damaged
by rough handling, especially while the analyzer is powered.
o
Overtightening bolts will damage or deform the mounting
hardware.
•
CAUTION:
o
Grounding the EC100 measurement electronics is critical. Proper
grounding to Earth will ensure maximum electrostatic discharge
(ESD) and lightning protection and improve measurement
accuracy.
o
Do not connect or disconnect the gas analyzer or sonic
anemometer connectors while the EC100 is powered.
o
Resting the analyzer on its side during the zero-and-span
procedure may result in measurement inaccuracy.
3. Initial Inspection
Upon receipt of your equipment, inspect the packaging and contents for
damage. File damage claims with the shipping company.
Model numbers are found on each component. On cables, the model number is
located both on the sensor head and on the connection end of the cable. Check
this information against the enclosed shipping document to verify the expected
products and that the correct accessories are included.
4. Overview
4.1 General
The EC150 measures absolute densities of carbon dioxide and water vapor.
The EC150 analyzer was designed specifically for open-path, eddy covariance
flux measurement systems. The EC150 gas analyzer head connects directly to
Campbell Scientific’s EC100 electronics. The EC150 is commonly used with a
CSAT3A sonic anemometer head. When the CSAT3A is used in conjunction
with the EC150, the EC100 can make gas and wind measurements
simultaneously. Similarly, the EC100 can simultaneously record measurements
from temperature sensors and a pressure transducer.
The EC150 analyzer has a rugged, aerodynamic design with low power
requirements, making it suitable for field applications including those with
remote access.
4.2 Features
The EC150 has been designed specifically to address issues of aerodynamics,
power consumption, spatial displacement, temporal synchronicity, and to
minimize sensitivity to environmental factors.
The analyzer windows are scratch resistant and treated with a durable
hydrophobic coating that facilitates shedding of raindrops from critical
surfaces. The coating also impedes the accumulation of dust and deposits, and
keeps the surfaces cleaner over longer periods of time. To minimize data loss
