Detailed Description
CS650-LC由连接到印刷电路板的两个30厘米长的不锈钢棒组成。电路板封装在环氧树脂中，并且屏蔽电缆连接到电路板以进行数据记录器连接。
The CS650-LC measures propagation time, signal attenuation, and temperature. Dielectric permittivity, volumetric water content, and bulk electrical conductivity are then derived from these raw values.
测量的信号衰减用于校正对反射检测的损耗效果，从而衡量传播时间测量。该损失效应校正允许散装EC≤3dsm的土壤中准确的水含量测量-1不进行土壤特定校准。
土壤散装电导率也从衰减测量计算。热接触热敏电阻与靠近环氧树脂表面的探针杆测量温度。横向安装传感器提供准确的土壤温度测量与水含量相同。在其他方向上的温度测量将是杆位入口附近的区域的环氧树脂。

Additional Compatibility Information
RF Considerations
External RF Sources
External RF sources can affect the probe’s operation. Therefore, the probe should be located away from significant sources of RF such as ac power lines and motors.
Interprobe Interference
Multiple CS650-LC probes can be installed within 4 inches of each other when using the standard data logger SDI-12 “M” command. The SDI-12 “M” command allows only one probe to be enabled at a time.
安装工具
14384试点工具
The 14384 Pilot Tool has rods with similar diameters and the same spacing as the probe. The tool can be driven into the soil using force levels that might damage the probe. After removing the 14384, the probe is inserted into the established holes.
14383 Installation Tool
14383安装工具可用于帮助在插入期间保持杆的适当间隔和平行方向。通过最小化土壤干扰，可以使用14383可以减少测量误差。

大多数坎贝尔科学传感器可作为-L提供，表示用户指定的电缆长度。如果传感器被列为-LX模型（其中“x”是其他字符），则该传感器的电缆具有用户指定的长度，但它终止具有唯一系统的特定连接器：
- An –LC model has a user-specified cable length for connection to an ET107, CS110, or retired Metdata1.
- An –LQ model has a user-specified cable length for connection to a RAWS-P weather station.
如果传感器在主型号之后没有-L或其他-LX指定，则传感器具有设定的电缆长度。电缆长度在产品订购信息中的描述字段的末尾列出。例如，034B-ET模型的描述描述了“Met One Wind for Et Station，67英寸电缆。”。产品具有集合电缆长度终止，作为默认尾纤。
If a cable terminates with a special connector for a unique system, the end of the model number designates which system. For example, the 034B-ET model designates the sensor as a 034B for an ET107 system.
- -et模型与ET107气象站的连接器终止。
- –ETM models terminate with the connector for an ET107 weather station, but they also include a special system mounting, which is often convenient when purchasing a replacement part.
- –QD models terminate with the connector for a RAWS-F Quick Deployment Station.
- –PW models terminate with the connector for a PWENC or pre-wired system.
-
Not every sensor has different cable termination options. The options available for a particular sensor can be checked by looking in two places in the Ordering information area of the sensor product page:
- Model number
- Cable Termination Options list
If a sensor is offered in an –ET, –ETM, –LC, –LQ, or –QD version, that option’s availability is reflected in the sensor model number. For example, the 034B is offered as the 034B-ET, 034B-ETM, 034B-LC, 034B-LQ, and 034B-QD.
所有其他的电缆终端选项,如果艾娃ilable, are listed on the Ordering information area of the sensor product page under “Cable Termination Options.” For example, the 034B-L Wind Set is offered with the –CWS, –PT, and –PW options, as shown in the Ordering information area of the 034B-L product page.
笔记：随着较新产品的添加到我们的库存中，通常，我们将在单个传感器模型下列出多个电缆终端选项，而不是创建多个型号。例如，HC2S3-L具有用于将其连接到CS110的-C电缆终端选项，而不是提供HC2S3-LC模型。
-
许多坎贝尔科学传感器可提供不同的电缆终端选项。这些选项包括以下内容：
- The –PT (–PT w/Tinned Wires) option is the default option and does not display on the product line as the other options do. The cable terminates in pigtails that connect directly to a data logger.
- - c (- c w / ET / CS110连接器)选项,cable terminates in a connector that attaches to a CS110 Electric Field Meter or an ET-series weather station.
- In the –CWS (–CWS w/CWS900 Connector) option, the cable terminates in a connector that attaches to a CWS900-series interface. Connection to a CWS900-series interface allows the sensor to be used in a wireless sensor network.
- In the –PW (–PW w/Pre-Wire Connector) option, the cable terminates in a connector that attaches to a prewired enclosure.
- In the –RQ (–RQ w/RAWS Connector) option, the cable terminates in a connector that attaches to a RAWS-P Permanent Remote Automated Weather Station.
笔记：电缆终端选项的可用性因传感器而异。例如，传感器可能没有，两个或多个选项可供选择。如果没有为特定传感器列出所需的选项，请联系Campbell Scientific进行帮助。
