Technical Specifications Wind Direction Vane Output and Range Analog DC voltage output proportional to wind direction angle with excitation voltage supplied by data logger, 360° continuous mechanical rotation, direction range, 10k potentiometer, 352° electrical, 8° open or dead band. Wind Direction Vane Performance Threshold (0.9 mph or .402 m/s) Accuracy (Potentiometer linearity within 1%) Life expectancy (50 million revolutions or 4-6 years operation) Materials of Construction Shaft tower (316 stainless steel) Shaft (Hardened 303 stainless steel) Wind Vane Housing (316 stainless steel) Wind Vane and Hub Assembly (316 stainless steel) Bearings (Double shielded and hardened stainless steel balls) Electrical Technical Data Direction range (352° electrical with 8° open or dead band) Signal (Analog DC voltage from precision conductive potentiometer, resistance 10K ) 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.
