Campbell Scientific - Model A100LK-L - Vector Anemometer
From Wind Speed and Wind Direction Sensors
The A100LK is an anemometer suitable for your general meteorology applications and 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 data loggers. The sensor is constructed from anodized aluminum alloys, stainless steel, and weather-resistant plastics for long life. It is used as part of our WMS100 wind-monitoring system.
Detailed Description
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.
Benefits and Features
- IEC Class 1 performance
- Low power consumption
- High rate of pulses per revolution produced makes it suitable for wind-surveying applications where turbulence is estimated
- Bearings protected from the entry of moisture droplets and dust, resulting in an instrument suitable for permanent exposure to the weather
