Benefits and Features

  • Compatible with most Campbell Scientific data loggers
  • Extremely long-wearing, corrosion-resistant, oversized ceramic bearings to increase service life many times longer than standard stainless-steel bearings
  • Oversized propeller shaft
  • High-pitch propeller
  • Locking propeller nut
  • Sealed, heavy-duty cable pigtail
  • Rugged enough for harsh environments
  • Constructed with thermoplastic material that resists corrosion from sea-air environments and atmospheric pollutants
  • Compatible with the LLAC4 4-channel Low-Level AC-Conversion Module, which increases the number of anemometers one data logger can measure
  • Compatible with the CWS900-series interfaces, allowing it to be used in a wireless sensor network

Additional Compatibility Information

Mounting

The 05108-L can be attached to a CM202, CM204, or CM206 crossarm via a 17953 Nu-Rail Crossover Fitting or CM220 Right-Angle Mounting Bracket. Alternatively, HD wind monitors can be attached to the top of our stainless-steel tripods via the CM216 Sensor Mounting Kit.

Wind Profile Studies

Wind profile studies measure many wind sensors. For these applications, the LLAC4 4-Channel Low Level AC Conversion Module can be used to increase the number of Wind Monitors measured by one data logger. The LLAC4 allows data logger control ports to read the wind speed sensor’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 05108's propeller uses one pulse count channel on the data logger. Its wind vane requires one single-ended channel and access to an excitation channel. (The excitation channel can be shared with other high-impedance sensors.)

Programming

The 05108's propeller 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 but present in the CR9000X).
