Construction of sensor body : brass housing and stainless steel shaft .
Principle of operation:
anemometer is a fast response, low threshold opto electronic anemometer. When
rotated by wind, a chopper on the anemometer shaft interrupts an infra red light source ,
generating pulses from a photo transistor. The signal is amplified and fed through a line driver .
The frequency is proportional to wind speed. The anemometer is provided with a 3 pin
connector for easy replacement and comes with 10 meters of shielded cable.
