The Richards D5CH Series HeatedWind Direction Vane was speci cally
designed for high wind speeds in harsh cold winter environments. The
D5CH is the heated version of our D5C Series Wind Vane. The D5CH has
all of the great features of the standard D5C compact wind vane but
with the addition of a powerful internal heater to prevent the bearings
from freezing in winter conditions.
All D5CH heated wind vane components are manufactured from
Stainless Steel bar stock for superior strength and corrosion resistance.
The D5CH vane assembly rotates on two precision grade, shielded,
stainless steel ball bearings. These bearings can be replaced in minutes
right in the eld with a simple screw driver and without disconnecting
the sensor cable or the wind sensor from its mounting.
The D5CH wind vane creates an analog DC voltage output signal for
directional degrees using a robust sealed 10K potentiometer element.
The D5CH heated wind sensor will quickly mount on any .5" O.D.
standard tubing using the three large set screws on the body. These
heated wind vanes will also mount on our BHC Series Buck Horn
Crossarms or Horizontal Booms. The internal wind sensor heater will
require a SJB Series Heater Control Box.
