概览

03002 使用一个3-杯风速计和一个风向标测量风速风向。可与Campbell 的数据采集器连接,不需信号调节。

优势与特点

  • 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
  • Compatible with the CWS900-series interfaces, allowing it to be used in a wireless sensor network

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).
