适用于Campbell公司所有的数据采集器
概览
03101 3-杯风速计包括在我们的03001风速风向传感器中。可根据应用单独采购风速计。03101可与Campbell Scientific的数据采集器连接，测量风速计的脉冲信号，并转换成相应的单位，例如 mph, m/s, knots。
优势与特点
- Ideal for applications that do not require wind direction measurements
- Compatible with most Campbell Scientific data loggers
- Designed for continuous, long-term, unattended operation in adverse conditions
- Small size, simplicity, and rugged construction provide a quality instrument for a modest price
- Ideal for wind profile studies
- Compatible with the LLAC4 4-channel Low-Level AC-Conversion Module, which increases the number of anemometers one data logger can measure
- Campbell Scientific version uses shielded bearings, which lowers the anemometer's starting threshold

技术说明
03101 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，数据采集器的脉冲通道测量交流正弦波的频率，并转换为风速单位(mph, m/s, knots)。Campbell Scientific版本的03101使用屏蔽式轴承，可降低风速计的监测限值。

Additional Compatibility Information
Mounting
The 03101 anemometer is supplied with a galvanized 10-in.-long x ¾-in. IPS threaded pipe, which mounts to a crossarm via a CM220 mount or 1049 Nu-Rail fitting. The 03101 can also be mounted to the top of a CM106B or a 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
The 03101 uses one pulse count channel on the data logger.
Programming
The 03101 is read by the PulseCount Instruction in CRBasic and by Instruction 3 (Pulse Count) in Edlog. Wind speed measurements can be taken and processed with any of the data loggers.

-
For information, refer to the “Calibration” section at the end of the instruction manual.
-
Very low voltage outputs from the sensor could be the result of a bad coil or an internal magnet that was mounted incorrectly. Refer to the “Troubleshooting” section of the instruction manual for more information. If it is necessary to return the sensor to Campbell Scientific for repair, request a return material authorization (RMA) number by following the steps listed on our Repair and Calibration page.
-
No. But using a LLAC4 will convert the ac signal for up to four 03101-L sensors (and other ac output anemometers) to individual 0 to 5 Vdc TTL level square wave outputs. For more information, see the LLAC4 specification information.
-
The pulse output can’t be converted easily to a 4 to 20 mA output without additional equipment. For a wind monitor designed to generate a 4 to 20 mA output, refer to the R. M. Young website.
-
The cup assembly can be replaced with pn 4609, Replacement Wind Speed Cup Assembly for 03001 or 03101.
-
Follow these steps:
- Remove the screw that attaches the 03101-L to the pipe mount fitting.
- Set the screw aside, but do not discard it.
- Mount the plastic flange of the 03101-L sensor to the underside of the crossarm.
- Use the screw to secure the sensor to the crossarm.
-
No. Installing the anemometer in a tilted position will cause damage to the bearings and the shaft, and the bearings will be infiltrated with water and dust.

03101-L Specifications
Gust survival: 134 mph (60 m/s)
Accuracy: ±1.1 mph (0.5 m/s)
Threshold (w/ shielded bearings): 1.1 mph (0.5 m/s)
Distance constant: 7.5 ft (63% recovery)014A-L Specifications
Operating range: 0 to 100 mph (0 to 45 m/s)
Accuracy: ±0.25 mph (0.11 m/s) or ±1.5%
Threshold: 1 mph (0.45 m/s)
Distance constant (aluminum cups): 15 ft (4.6 m)
Distance constant (optional fast response Lexan cups): < 5 ft (1.5 m)Any mechanical wind speed sensor will need to have its bearings replaced on a regular basis. The 03101-L is a less expensive sensor and does not have a reed switch to replace. It’s easier to work on, and the bearings are less expensive. The turret covering the bearings is longer and protects the bearings better from dust and debris. The cups and sensor body are plastic and more fragile, so careful handling is required, but they hold up well after the sensor is installed.
The 03101-L comes with a ¾ in. pipe. The 014A-L has a 1 in. pipe.

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。
