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
There are no contacts or brushes in the
assembly. The AerVaneTM is made from
anodized aluminum, stainless steel,
ultraviolet inhibited PVC and Lexan®
A RainWise interface can provide an RS-
232 output or any desired analog output
including 4-20 milliamps, 0-1 VDC, etc.
