Cảm biến đo gió Campbell Scientific A100LK-L
The A100LK is an anemometer for general meteorology and for wind-energy surveys. Its low power consumption and wide power-supply range make it popular for remote locations with no access to ac power, and its pulse/frequency signal is ideal for use with Campbell Scientific dataloggers. The sensor is constructed with anodized aluminum alloys, stainless steel, and weather-resistant plastics for long life. It is used as part of our WMS100 wind-monitoring system.
Rotation of the A100LK’s three-cup rotor is electronically converted to pulse output signals proportional to wind speed. The A100LK produces a higher rate of pulses per revolution (up to 13) compared to relay based sensors, making it suitable for wind surveying where turbulence needs to be estimated.
