技术说明
05305-AQ 风速风向传感器 采用轻便，紫外线稳定的热塑塑料，不锈钢和阳极电镀铝材质。耐热塑料可抗击海洋空气环境的侵蚀，抵抗大气污染。精密级别的不锈钢滚珠轴承用于旋桨轴承和立式轴承。
专为海岸和海洋应用设计，经久耐用，05106采用防水的轴承润滑剂以及密封的高性能的尾线代替了标准接线盒。
05305 用四叶旋桨测量风速。旋桨转动产生与风速成正比的交流正弦波频率。传感器线圈中感应的交流信号由安装在传动轴六极磁铁生成。线圈固定在不能旋转的主安装组件的中部，省去了滑环和电刷。
连接在内部电位计上的机身状的传感器被用来感应风向。数据采集器将已知的精确的激发电压传向电位计元件。输出的模拟电压信号与方位角成正比。
05305-AQ 风速风向传感器专为测量空气质量设计，低启动阈值，响应迅速，高精确度。它符合或超过由以下监管机构公布的要求：
- 美国环保局环境监测预防指南--显着恶化（PSD）和现场气象仪器要求表征扩散点源
- 美国核监管机构NRC监管指南1.23--核电站气象程序
- 美国核学会核电站气象标准

Additional Compatibility Information
Mounting
The 05305 can be attached to a crossarm via a 17953 NU-RAIL fitting or CM220 Right Angle Mounting Bracket. Alternatively, it can be attached to the top of a CM106B or a stainless-steel tripod via the CM216 Sensor Mounting Kit.
Data Logger Considerations
The 05305's propeller uses one pulse count channel on the data logger. Its wind vane requires one single-ended channel and access to an excitation channel (the excitation channel can be shared with other high impedance sensors).
Programming
The 05305's propeller is measured by the PulseCount Instruction in CRBasic and by Instruction 3 (Pulse Count) in Edlog. The wind vane is measured by the BrHalf Instruction in CRBasic and by Instruction 4 (Excite-Delay-SE) in Edlog. The measurements are typically processed for output with the Wind Vector instruction (not present in the CR500 or CR9000 but is present in the CR9000X).

-
This depends on what is broken. Typically, Campbell Scientific can repair the unit, and the user does not have to purchase a new one.
-
The short answer is less than 0.01 mA. The wind speed signal requires no power. The wind direction portion of the sensor only uses a maximum of 0.5 mA when excited with 5 Vdc, and then it is only on for 0.016 s for every measurement. When the wind direction is measured every second (typical), the average current drain is less than 0.01 mA.
-
Orientation of the wind monitor is done after the data logger has been programmed, and the location of True North has been determined. True North is usually found by reading a magnetic compass and applying the correction for magnetic declination, where magnetic declination is the number of degrees between True North and Magnetic North. Magnetic declination for a specific site can be obtained from a USFA map, local airport, or through a computer service.
-
The information included on a calibration sheet differs with each sensor. For some sensors, the sheet contains coefficients necessary to program a data logger. For other sensors, the calibration sheet is a pass/fail report.
-
This depends on the information contained in the calibration sheet:
- If the calibration sheet contains coefficient information, Campbell Scientific keeps a copy, and a replacement copy can be requested.
- If the calibration sheet does not contain coefficients, Campbell Scientific does not keep a copy. It may be possible to contact the original manufacturer for a replacement copy.
-
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。
