03101-L Wind Sentry Anemometer

The 03101 uses a cup wheel assembly to measure wind speed. Rotation of the cup wheel produces an ac sine wave that is directly proportional to wind speed. The frequency of the ac signal is measured by a data logger pulse count channel, then converted to engineering units (mph, m/s, knots). Campbell Scientific’s version uses shielded bearings, which lowers the anemometer’s threshold.

Benefits and Features 

• • 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
