Product Description
DWD 8601 MB wind vane is a counter balanced, low threshold wind vane. A Linear, wire wound endless potentiometer is coupled to the vane by an SS shaft. As the vane turns, it rotates a stainless-steel shaft which is coupled to the potentiometer. This potentiometer has excellent linearity, very low starting torque. The north of the wind vane is marked on its body. This line is to be aligned with actual North with the help of a prismatic compass, at the time of installation. Sensor gives minimum resistance at North (i.e., 0 degree approximately 20 ohms). The resistance output is linearly proportional to the position of the wind vane.
