Introduction
- Dynalab Weather Technologies anemometer is a fast response, low threshold up to electronic anemometer. When rotated by wind, a chopper on the anemometer shaft interrupts the infrared light beam 18 times per revolution, generating pulses from a phototransistor. The signal is amplified and fed through a line driver who can drive 500 meters of cable. The frequency is proportional to wind speed. The anemometer is provided with 3 pin connector for easy replacement.
- DWD wind vane is a counterbalanced, 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 and very low starting torque. The use of a single wiper increases the life expectancy of the potentiometer. The north of the wind vane is marked on its body. This line is to be aligned with the actual North with the help of a prismatic compass, at the time of installation. The sensor gives minimum resistance at North (i.e., 0 degrees approximately 20 ohms). The resistance output is linearly proportional to the position of the wind vane. This Resistance is converted to a voltage in the Interface unit in such a way that 0 degrees to 360 degrees cover a range of 0 to 1 volt
