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.

Please note: The following shows notable compatibility information. It is not a comprehensive list of all compatible products.
The A100LK uses one pulse count channel on the data logger.
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.
