VENTUS-UMB
Lufft sensors, both in plastic and metal housing, use ultrasonic technology for the percise measuring of wind speed and direction. Lufft sensors are tested in thier own high-percision wind tunnel, so that you know how strong and where the wind is blowing.
Recommended for:
- wind turbines
- marine/ships
- meteorology
- building automation
