Mounting
The HC2S3 should be housed in a 41003-5 10-plate naturally-aspirated solar radiation shield. This radiation shield mounts to a tripod or tower mast, crossarm, or user-supplied pole.

Campbell Scientific offers two filter tips:
- The HC2S3-L comes with a polyethylene filter that provides protection against fine dust particles, doesn't absorb or retain water, and offers a good response time.
- A Teflon filter can be ordered separately (pn 27755, HC2S3 Replacement Teflon Filter). This filter has a smaller pore size (10 micron) that provides good protection against fine dust particles and salt (marine environments), but it has a slightly slower response time than the polyethylene filter.
-
To measure ambient temperature and relative humidity (RH), mount the HC2S3-L probe inside a 41003-5 or 41003-5A 10-Plate Radiation Shield. The 27731 hex plug is shipped with the HC2S3-L so that it can be used with older 10-plate radiation shield models. The 6-plate radiation shield (pn 41303-5A) cannot be used with the HC2S3-L.
-
The sensor should not be cleaned with water. If the sensor is dirty, the filter should be changed or cleaned more frequently. A dirty filter can be cleaned with distilled water.
-
Note the difference between calibration and a field check. Calibration cannot be done in the field, as it requires an experienced technician and specialized equipment.
Field checks of measurements can be done to determine if the data make sense with the real-world conditions. Follow these steps to field check a sensor:
- 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.
- 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.
- 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.
- The 107, 108, 109, 110PV-L, and BlackGlobe-L temperature 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. For more information, refer to the “Maintenance and Calibration” section of the CS215 instruction manual.
- The HMP60-L has a replaceable chip for relative humidity only. For more information, refer to the “Maintenance” section of the HMP60 instruction manual.

大多数 Campbell Scientific 传感器的型号中都带有 –L，它表示用户指定线缆长度。如果传感器型号名称列有 –LX (这里 “X” 是其它的某个字符), 那么该传感器需要用户指定长度，但线缆尾端会配有用于某个独特系统的特殊快速接头：
- –LC 表示用户指定线缆长度，所配快速接头用于 ET107, CS110, 或已停产的 Metdata1 系统。
- –LQ 表示用户指定线缆长度，所配快速接头用于 用于 RAWS-P 气象站。
如果一个传感器的主型号数字的后面没有被指定 –L 或其它的 –LX 字符，那么该传感器将具有固定的线缆长度。在产品页面订购栏中 (Ordering tab) 的描述字段的末尾，会列出线缆的长度。例如 034B-ET 型号的描述字段含有信息：Met One风传感器适用于ET气象站，67英寸线缆 (Met One Wind Set for ET Station, 67 inch Cable)。产品按固定的线缆长度做尾端处理，默认是尾线方式。
如果线缆尾端配有用于某个独特系统的特殊快速接头，则型号尾部的字符会指定该传感器用于哪一个系统。例如，034B-ET 型号表明该传感器是一个 034B 且用于 ET107 系统。
- 以 –ET 结尾的型号的传感器配备快速接头，用于 ET107 气象站。
- 以 –ETM 结尾的型号的传感器配备快速接头，用于 ET107 气象站，但它们也含有一个特殊的系统安装支架，在订购一个备件时，所配的支架经常是便捷实用的。
- 以 –QD 结尾的型号的传感器配备快速接头，用于 RAWS-F 快速配置气象站。
- 以 –PW 结尾的型号的传感器配备快速接头，用于 PWENC 预接线机箱或预接线系统。
-
不是每一种传感器都有不同的线缆尾端选项。通过查找传感器产品页面的订购栏 (Ordering tab) 中的两个位置，可以检查某种特定传感器的可用的线缆尾端选项：
- 产品型号
- 线缆尾端选项列表
如果传感器以 –ET, –ETM, –LC, –LQ, 或 –QD 等版本的型号供应，那么线缆尾端选项已经反映在该传感器的产品型号中。例如，034B 以 034B-ET, 034B-ETM, 034B-LC, 034B-LQ, 和 034B-QD 等型号供应。
所有其它的线缆尾端选项，如果可用，会列在该传感器产品页面的订购栏 (Ordering tab) 中的线缆尾端选项 (“Cable Termination Options) 区域。例如，034B-L 风速风向传感器具有 –CWS, –PT, 和 –PW 等线缆尾端选项，显示在 034B-L 产品页面的 订购栏 (Ordering tab) 位置。
注： 当更新的产品添加到我们的库存中时，一般来说，我们会在单个传感器的产品型号下面列出多种线缆尾端选项，而不是创建多个产品型号。例如，HC2S3-L 具有 –C 线缆尾端选项用于连接到 CS110，而我们并没有使用 HC2S3-LC 产品型号。

Campbell Scientific 的很多传感器都有可行的不同线缆尾端处理选项，包括以下几种：
- –PT (–PT w/Tinned Wires，镀锌尾线) 是默认选项，不显示在产品行中，而其它选项会显示在产品行中。线缆末端为尾线方式，可直接连接到数据采集器。
- 在 –C (–C w/ET/CS110 Connector，CS110快速接头) 选项中，线缆尾端所配的快速接头可连接到 CS110 电场计或 ET-系列的气象站。
- 在 –CWS (–CWS 带 CWS900 快速接头) 选项中，线缆尾端所配的快速接头可连接到 CWS-系列的接口。连接到 CWS900-系列接口使得传感器可被用于无线传感器网络中。
- 在 –PW (–PW 带预接线快速接头) 选项中，线缆尾端所配的快速接头可连接到预接线机箱上。
- 在 –RQ (–RQ 带RAWS 快速接头) 选项中，线缆尾端所配的快速接头可连接到 RAWS-P 永久配置远程自动气象站。
注： 线缆尾端选项的可行性因传感器而异。例如，传感器可能会有 无选项、两个选项或几个选项可供选择。如果预期的选项没有列在所指定的传感器中，请联系 Campbell Scientific 的应用工程师寻求帮助。
