技术说明
EC155的气体测量腔室的容积很小（5.9 ml），最小化了气样的驻留时间（在7 LPM的名义系统流速下，约 50 ms）。在低系统功耗（12 W)的同时，提供了优异的频率响应性能（5.8 Hz的半功率谱波宽）。
涡度相关测量
CO2 和 H2O 由EC155闭路气体分析仪测量，三维风速和声温由CSAT3A超声探头测量。
CPEC200系统机箱
一个 16英寸x18英寸 的玻璃纤维耐候机箱，用于安装数据采集、可选的存储外设、可选的气阀模块、以及与闭路气泵模块相连的电子接口。系统机箱可以被固定到主桅杆上、CM106的斜腿上、直立塔的立柱上或大直径的立杆上。
CPEC200的气泵模块
气泵模块是CPEC200闭路系统的标准部件，包含一个带无刷直流电机的小的双头隔膜泵，固定在玻璃纤维机箱的内部；一条集成的电缆连接气泵模块与系统机箱，提供供电、温度测量与控制、压力测量以及气泵流速测量与控制。
气阀模块（可选）
Campbell Scientific提供两种气阀模块。基本的3阀模块（货号： 27559）让CPEC200系统具有自动实施零点校准、CO2跨度校准和H2O跨度校准的功能。而6阀系统（货号：26578）具有更多的三个气阀，可以接入更多的CO2跨度气瓶。气阀模块位于CPEC200系统机箱内，分支管的出口具有一个比例阀用于自动控制切换 零点/跨度 气体。

CR3000 OS v.32.07 (4.39 MB) 15-05-2024
Execution of this download installs the CR3000 Operating System and Compiler on your computer. It also updates the CR3000 support files for the CRBasic Editor.
Note: The Device Configuration Utility is used to upload the included operating system to the datalogger.
Upgrading from versions prior to version 28 of the Operating System will reset the datalogger’s CPU drive. This is due to a change in the format of the file system from FAT16 to FAT32. In order for the datalogger to operate correctly, as part of the upgrade, the CPU drive is formatted to FAT32. Any programs stored and running from the CPU drive will be lost. It is not recommended to update the datalogger’s Operating System over a remote connection where program control regulates the communication equipment (turning it on or off, etc.). In these cases, an on-site visit and a backup using DevConfig’s backup utility is necessary to update the datalogger’s Operating System.
Watch the Video Tutorial: Sending an OS to a Local Datalogger.
In all cases where the datalogger is being updated from an Operating System prior to 28, the use of DevConfig’s backup utility is recommended due to the CPU drive being formatted using the new FAT32 format.

常见问题解答
CPEC200: 16
展开全部收起全部
-
The heater for the CPEC200 is not positioned along the intake pipe. The heater is in the "snout/rain-cap" of the vortex intake.
-
The pump module fan continues to draw 0.7 W while operational.
-
Yes, the heater is controlled the same way. Campbell Scientific recommends leaving the heater on all the time.
-
The inserts prevent the tubing from collapsing as the ferrules are swaged onto the tubing. Although it is possible to make a leak-tight connection without an insert, the insert provides added protection against leaks. This is particularly true for tubes at negative pressure and for repeated tubing disconnect/connect cycles.
-
The threads on the nut and fitting have likely been damaged because they were over tightened. Replace both the nut and the fitting.
-
If the pump fails, it must be replaced. Contact Campbell Scientific for details. For the process of returning equipment to Campbell Scientific, refer to the Repair and Calibration page.

Sample cell windows should be cleaned when the optical signal strength (CO2 and/or H2O) diminishes to 80%. A conservative approach is to change the blue filter (Campbell Scientific pn 31210, Parker pn 9922-05-DQ) at the same time that the windows are cleaned. The inside of the vortex body may require cleaning with a lint-free wipe and clean water or isopropyl alcohol at the time of the filter change.
An increased magnitude of cell-pressure drop may also indicate a clogged filter. The table below shows some example cell pressure readings in our laboratory with the CLIP-ON vortex. Readings with the “100% clogged” filters were made by physically plugging the bypass tubing. Note: These pressures do not apply to the new standard vortex intake, which has more pressure drop and requires a different filter kit (Campbell Scientific pn 32203) that consists of a filter with pre-installed Swagelok nuts.

The pump has a one-year warranty. Although the pump’s manufacturer does not specify an expected lifetime, the pump’s lifetime is expected to be significantly longer than one year.

Yes, the pump works a little harder with the new vortex. The recommended flow for the new vortex system is 8 LPM (6 to sample cell + 2 to bypass). 7 LPM was recommended for the original system. Also, the sample cell “differential” pressure is slightly lower (~-6kPa_new versus ~-3kPa_original). It’s a balance of parameters to maintain good frequency response, low power, and low maintenance.
