Ideal for wind-energy applications
Overview
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.

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.

No. Cables are attached and sealed on the sensor by the manufacturer. Whenever possible, purchase a sensor with the desired cable length. Alternatively, a new sensor can be purchased with a foot of cable and then spliced onto the existing cable. Splicing cable together, however, increases the likelihood that water may enter the cable and cause shorting, corrosion, and some other potential issues, which in turn can cause measurement issues. Because of the potential issues, do not splice any sensor cable without first contacting Campbell Scientific to discuss the sensor in detail.
-
Yes. Every A100LK-L ships with a MEASNET calibration certificate.
