1. 用HMP60-L取代退出的HMP45C-L时，可以使用相同的辐射屏蔽吗？

   HMP60-L（带坎贝尔科学电缆）不能与41003-5 10板辐射屏蔽一起使用，而无需使用额外的硬件。了解更多信息，refer to the Compatibility information on the HMP60-L product page. The standard radiation shield for the HMP60-L is the 41303-5A.

2. HMP60-L上的相对湿度（RH）传感元件应该多久被更换一次？

   In general, the element should be replaced every two years. By doing a field check (that is, comparing the RH reading with a reference), the element can be used until the relative humidity measurement is out of tolerance.

3. CS215-L和HMP60-L之间有什么区别？

   The most significant difference is that the CS215-L has an SDI-12 output and that the HMP60-L has a voltage output. Additional differences are outlined in the “空气温度和相对湿度“手册，比较所有坎贝尔科学温度和相对湿度传感器。

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

   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.
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

   如果一个传感器提供一个外星人,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：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。

6. 可以在温度传感器或温度和相对湿度传感器上进行哪种类型的现场检查，以确定它是否在指定精度范围内或需要校准？

   注意校准和现场检查之间的差异。校准不能在现场进行，因为它需要经验丰富的技术人员和专业设备。

   可以进行现场测量检查以确定数据是否与真实世界的条件有意义。按照以下步骤查看传感器：

   1. Find a second sensor of the same type as the installed sensor whose data is in question. The second sensor will be used as a benchmark sensor and should be known to be accurate or recently calibrated.
   2. At the site, take readings using both sensors under the same conditions. The best practice is to measure both sensors side-by-side at the same time. Note that the sensors will never have the exact same measurement.
   3. Depending on the sensor model, if the difference in the readings of the installed and benchmark sensors is greater than the sum of the accuracies for both sensors, either return the installed sensor to Campbell Scientific for calibration or replace the appropriate chip.
   • 107, 108, 109, 110 pv-l, BlackGlobe-Lrature sensors can be calibrated.
   • The HC2S3-L and HMP155A-L temperature and relative humidity sensors can be calibrated.
   • The CS215-L has a replaceable chip for temperature and relative humidity.了解更多信息，refer to the “Maintenance and Calibration” section of the CS215说明书。
   • HMP60-L仅具有可更换芯片的相对湿度。了解更多信息，请参阅HMP60的“维护”部分说明书。
7. What are the different cable termination options available for Campbell Scientific sensors?

   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.
   • 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。

8. 将与无线传感器接口兼容的传感器连接到无线网络中的CR800，CR1000或CR3000兼容的传感器所需的是什么？

   为了将与无线传感器接口兼容到无线网络中的传感器，需要CWS900系列无线传感器接口，以及A205 CWS-To-PC接口来配置它。
