The Vector A100LM/PC3 Anemometer is a low-power optoelectronic cup anemometer developed for high-quality wind-speed measurement in wind-resource assessment, meteorological monitoring and remote met-mast installations. Its low-inertia three-cup rotor interrupts an optical beam to generate a high-frequency pulse output proportional to wind speed. The current Ammonit configuration provides a 0–75 m/s measurement range, 0.2 m/s starting speed, 0.05 m/s resolution and extremely low power consumption of typically less than 1 mA, making the A100LM/PC3 particularly suitable for autonomous battery- or solar-powered wind-measurement systems.

Key Features
