Cup Anemometer

Listing ID #1296057

We offer cup anemometer. Cup anemometer specifications:
wind speed sensor : 3 cup anemometer.
Sensing : 3 cup assembly mounted on friction free shaft and
coupled to a chopper.
Starting threshold : 0.3 meterssec .
Range : 0 to 65 meterssec .
Distance constant : 2.5 meters
output : ttl pulses output proportional to wind built in line driver to
drive long cable > 50 ohms loop resistance.
Accuracy : better than 0.5 ms up to 10 ms 2% fsd
diameter of cup : 50 mm.
Diameter of cup assembly : 165 mm.
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.
