The WeatherLog AerVaneTM with 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 AerVaneTM is made from anodized aluminum, stainless steel, ultraviolet inhibited PVC and Lexan® plastic.

The Aervane is optional for the PVmet and Agromet systems.
