1. Does every sensor come with a calibration sheet?

   Not every sensor comes with a calibration sheet. If a calibration sheet is included, it is listed in the “Ships With” section of the sensor’s product web page or it is specified when ordered.

2. 传感器电缆可以缩短吗？

   Sometimes, an old cable can be replaced with a new, shorter cable.

   Sometimes, an existing cable can be shortened by cutting the ends off. However, there are a few issues that could be encountered when doing this:

   • 一些传感器在辫子端具有桥梁完成电阻。
   • Some sensors are calibrated to length.
   • 有时，绝缘材料中的颜色可能与辫子端可见的颜色不同。

   由于潜在的问题，请勿在不先与Campbell Scientific详细讨论传感器的情况下切断任何传感器电缆。

3. If the cable attached to a sensor is too short, can more cable be spliced to the existing cable to make it longer?

   尽可能购买带有所需电缆长度的传感器。一些传感器具有用户指定的电缆长度，而其他传感器具有设置的电缆长度。

   Sometimes, an old cable can be replaced with a new, longer cable.

   通常，其他电缆不能插入现有电缆上，因为：

   • Some sensor cables have bridge completion resistors at the pigtail end
   • 一些传感器根据电缆长度进行校准
   • Sometimes the color in the insulation is not the same as that visible at the pigtail end
   • It is possible to introduce errors or malfunctions depending on the integrity of the splice

   Splicing cable together increases the likelihood that water may enter the cable and cause shorting, corrosion, and some other potential issues, which in turn can cause measurement issues.

   Because of the potential issues, do not splice any sensor cable without first contacting Campbell Scientific to discuss the sensor in detail.

4. What are the different cable length choices available for Campbell Scientific sensors?

   大多数坎贝尔科学传感器都可以作为–L提供，该传感器表示用户指定的电缆长度。如果将传感器列为–LX模型（其中“ X”是其他字符），则传感器的电缆具有用户指定的长度，但它用特定的连接器终止了独特系统：

   • 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名称，则传感器具有设置的电缆长度。电缆长度在产品订购信息中的描述字段末尾列出。例如，034B-ET型号的描述说明“遇到了一个为ET站的一组，67英寸电缆”。具有固定电缆长度的产品，默认情况下，带辫子。

   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 models terminate with the connector for an ET107 weather station.
   • –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.
5. Where are the available cable termination options listed for a particular sensor?

   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.

   All of the other cable termination options, if available, 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：由于通常将较新的产品添加到我们的库存中，因此我们将在单个传感器模型下列出多个电缆终止选项，而不是创建多个模型号。例如，HC2S3-L具有将其连接到CS110而不是提供HC2S3-LC模型的–C电缆终止选项。

6. What are the different cable termination options available for Campbell Scientific sensors?

   许多坎贝尔科学传感器都有不同的电缆终止选项。这些选项包括以下内容：

   • pt (pt w /镀锡线)选项是默认的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.
   • In the –C (–C w/ET/CS110 Connector) option, the 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：电缆终止选项的可用性因传感器而异。例如，传感器可能没有，两个或几个选项可供选择。如果未列出特定传感器的所需选项，请联系Campbell Scientific寻求帮助。

7. Can a sensor cable be replaced?

   很多时候，但并非总是如此，传感器的电缆可以用新电缆代替。如果原始电缆损坏或需要更改其长度，这将很有帮助。

   如果电缆使用连接器连接到传感器，Campbell Scientific将出售替换电缆。例如，05106CBL-L是05106-L的替换电缆。替换电缆在产品页面的订购信息区域的“替换零件”部分中列出。

   如果电缆通过可访问的端子块连接到传感器上，则可以购买原始电缆来替换它。例如，要替换05103-L风监视器上的电缆，请订购所需的长度pn 9721，，，，24 AWG 3扭曲的一对屏蔽的圣地滨电缆。As another example, the raw cable for a TE525-L Rain Gage ispn 9661，，，，22 AWG 1扭曲的一对屏蔽的圣地滨电缆。

   If the cable is an integral part of the sensor, the cable cannot be user replaced, and the sensor must be returned to Campbell Scientific. Some examples of sensors that fall into this category include the 107-L, 109SS-L, 229-L, CS547A-L, and CS650-L.
