Das CPEC310 ist ein schlüsselfertiges closed-path Eddy-Covariance (EC) System zum Langezeit-Monitoring der Flüsse von Kohlendioxid, Wasserdampf, Wärme und Impuls. Ein komplettes System besteht aus dem closed-path Gasanalytor (EC155 closed-path gas analyzer), 3D-Ultraschallanemometer (CSAT3A ), Datenlogger (CR6 ), Pumpe, Modul mit drei Ventilen zum autmatischen Nullabgleich von CO2 (H2O manuell) und Anschlussmöglichkeit für einen CDM-A116 für zusätzliche Sensoren.
Das Design des Einlasses des Gasanalysators und das kleine Probenzellvolumen (5.9 ml) wird eine excellente Frequenzantwort (4.3 Hz Grenzfrequenz) sehr geringem Stromverbrauch des Systems (12 W) möglich. Außerdem reduziert der spezielle Einlass mit Wirbel (United States Patent No. 9,217,692) die Wartung und verbessert die Frequenzantwort gegenüber herkömmlichen Filtern.
Geringere Durchflussraten ermöglichen es, dass das CPEC310 sehr wenig Strom verbraucht (12 W). Campbell Scientific stellt alle Komponenten des CPEC310, inclusive Datenlogger und EasyFlux™ DL Software her und dadurch wird das gesamte System einfach und verlässlich.

CO2 and H2O are measured with an EC155 Closed-Path Gas Analyzer. Three-dimensional wind speed and sonic air temperature are measured with a CSAT3A sonic anemometer head.
The CPEC310 has two enclosures: a fiberglass enclosure that houses the CR6 datalogger, pump module, three-valve module, and optional CDM-A116, and the EC100 enclosure for data processing. The CPEC310 can also be equipped with a scrub module for automatic zeroing of the EC155.
The pump module, a standard component of the CPEC310 system, consists of a small dual-head diaphragm pump with a brushless dc motor mounted inside a fiberglass enclosure. An integral cable connects the pump module to the CPEC310 system enclosure, which provides power, temperature measurement and control, pressure measurement, and pumping speed measurement and control.

This download is for the CR6 datalogger. Execution of this download places the Operating System file(.obj) on your computer. It also updates the CRBasic Editor compiler and support files.
Why Update? UID (unique identifier) is now utilized for enhancing security along with other features and bug fixes. With this OS update it is recommended that you also update the Device Configuration Utility to the most recent version so that new datalogger features are available in the utility.
Note: Campbell Scientific always recommends updating operating systems on site if possible. When remote updates are required, it is recommended that you implement the necessary precautions to handle unexpected OS upload complications. All datalogger settings should be retained when updated remotely. If you choose to roll back to a previous operating system, the datalogger settings will be reset to default.

No. A valve module is required to use the Scrub Module. Only the CPEC310 comes with a valve module.
The bottles of sieve for drop-in replacement contain the pellets and a membrane on top. The membrane is necessary to keep the pellets contained while allowing gas to pass over the zeolite. The bottle has the same footprint as the old magnesium perchlorate bottles. The amount in each bottle is listed on the bottle. The amount of sieve needed for each analyzer is the following:
The molecular sieve is a non-hazardous material that can be shipped to any country.
The molecular sieve has been demonstrated here by our engineering department to be effective at removing CO2 and H2O from the air sample. The change was made for two reasons:
The molecular sieve is a direct replacement for the old magnesium perchlorate bottles. The molecular sieve may be used for any Campbell Scientific analyzer that used the old bottles.
Yes. For more information, refer to the "CPEC200 Scrub Module Installation, Operation and Maintenance" appendix in the CPEC200 Closed-Path Eddy-Covariance System Instruction Manual.
