The V200A Ultrasonic wind sensor has a 30W heater and measures wind velocity, wind speed, wind direction and acoustic virtual temperature. This instrument is extremely precise and maintenance-free. V200A belongs to Lufft's WS family of professional intelligent sensors with digital and analog interfaces. The ultrasonic wind sensor is designed without mechanical parts as they have been used with traditional “cups and vanes”. Its robust design and precise measurements allow for efficiency and accuracy of project control. The V200A wind sensor is ideal for renewable energy applications and heated for use in cold weather climates.
