V200A
Extremely percise and maintenance-free measurement of wind velocity and wind direction as well as calculation of acoustic virtual temperature.
The ultrasonic wind sensor is designed without mechanical parts as they have been used with traditional "caps and vanes". The digital or analog output delivers instantaneous, average, min or max value with flexible measuring rate. The V200A-UMB is heated in case reaching critical ambient conditions.
Recommended for:
- meteorology
- building automation
The following outputs/protocols are available:
- NMEA
- ASCII
- UMB
- 4...20 mA analog
