技术说明
03002利用风杯转动测量风速。风杯的旋转产生与风速成正比的交流正弦波。数据采集器脉冲计数器可测量出交流信号的频率，然后将其转换成工程单位，例如mph, m/s, knots。Campbell Scientific版本的03002使用屏蔽式轴承，可降低风速计的监测限。
风向由电位计检测。随着精密的激发电压从数据记录器施加到电位计元件，输出信号是模拟电压，其与风向方位角成正比。

Additional Compatibility Information
Mounting
The 03002 is supplied with a 12-in.-long x 1-in. IPS unthreaded aluminum pipe, which mounts to a crossarm via a CM220 Mount or 17953 Nu-Rail fitting. The 03002 can also be mounted to the top of a CM106B or stainless-steel tripod via the CM216.
Wind Profile Studies
An ideal application for the Wind Sentry is wind profile studies. For this application, the LLAC4 4-channel Low Level AC Conversion Module can be used to increase the number of anemometers measured by one data logger. The LLAC4 allows data logger control ports to read the anemometer’s ac signals instead of using pulse channels. Data loggers compatible with the LLAC4 are the CR200(X)-series (ac signal ≤1 kHz only), CR800, CR850, CR1000, CR3000, and CR5000.
Data Logger Considerations
Programming
The anemometer 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).
常见问题解答

-
One cup cannot be replaced at a time. The whole cup assembly would need to be replaced. The cup assembly can be replaced by the user.
-
The 034B-L uses a switch closure for wind speed measurement, and the 03002-L uses a low-level ac output for wind speed measurement. Both use a pulse channel on the data logger to measure wind speed.
-
A CM202, CM204, or CM206 crossarm can be used. Select the appropriate crossarm for the application. To mount the sensor to the crossarm, use a CM220 (Right-Angle Mounting Bracket) or a 17953 (1- x 1-inch NU-RAIL Crossover Fitting). To mount the sensor to the top of a CM110-series tripod, use a CM216 (Apex Sensor Mount for SS Tripod).

It is possible, but Campbell Scientific does not recommend user replacement. Factory replacement is strongly recommended.

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。
