Aervane- Wind Speed and Direction Sensor
The WeatherLog AerVane was designed to meet or exceed the EPA guidelines for regulatory modeling applications.
The balanced propeller is supported in stainless steel instrument ball bearings. The propeller drives a serrated disc which generates pulses in an optical switch. The direction is obtained through an optical resolver.
There is no “dead band” and the resolution and accuracy are ±1.0 degrees. There are no contacts or brushes in the assembly. The AerVane is made from anodized aluminum, stainless steel,ultraviolet inhibited PVC and Lexan plastic.
A RainWise interface can provide an RS-232 output or any desired analog output including 4-20 milliamps, 0-1 VDC, etc.
The RainWise AerVane is guaranteed for five years.
- Meets or exceeds EPA monitoring guidelines
- Accuracy traceable to NIST
