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。

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.

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.
