Wind Speed and Wind Direction Sensors / A100LK-L
IEC 61400-12 Class 1 Anemometer
Ideal for wind-energy applications
Ideal for wind-energy applications
Overview
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.

- IEC Class 1 performance
- 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

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.

Additional Compatibility Information
Data Logger Considerations
The A100LK uses one pulse count channel on the data logger.
Programming
The A100LK is read by the PulseCount Instruction in CRBasic and by Instruction 3 (Pulse Count) in Edlog. Wind speed measurements can be taken and processed with any of the data loggers.
