Lufft VENTUS Ultrasonic anemometer, 240W heater, metal housing

Extremely precise and maintenance-free measurement of wind velocity and wind direction as well as calculation of acoustic virtual temperature.

Lufft VENTUS 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”.

The digital or analog output delivers instantaneous, average, min or max value with flexible measuring rate. The Lufft VENTUS is heated in case reaching critical ambient conditions. This ultrasonic wind sensor is made for cold climates!

Lufft VENTUS Ultrasonic Wind Sensor is Recommended for:

  • Wind turbines
  • Marine/ships
  • Meteorology
  • Building automation

The following outputs are available:

  • NMEA
  • UMB
  • 4... 20 mA, 0...10V
  • SDI12
