V200A Ultrasonic Wind Sensor
Extremely precise and maintenance-free measurement of wind speed and wind direction
Extremely precise 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 "cups 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 or building automation. The following outputs/protocols are available: NMEA, ASCII, UMB and 4.. 20 mA analog.
- Wind speed, wind direction, virtual temperature, barometric pressure
- Ultrasonic
- Maintenance-free measurement, suitable for extreme ambient conditions, ice-free operation, compatible interfaces
- SDI-12, RS-485, various RS-485-protocols, analogue output
- 8371.UA01
- Built-in data pre-processing, universal interfaces and selectable output protocols – compatible with OTT-dataloggers, commercially available HydroMet dataloggers and PLS systems
- Maintenance-free operation – no moving parts that can wear out thanks to ultrasonic measuring method; no need for re-calibration
- Suitable for all climate zones; also for solar-powered automatic meteorological stations
- Integrated heater that can be switched on if there is danger of frost – guarantees ice-free operation in extremely low temperatures until -40 °C
- Embedded algorithms that provides the wind speed and direction as actual and averaged values
- Wind gust calculation regarding WMO (Guide to Meteorological Instruments and Methods of Observation)
The robust and maintenance-free wind sensor is designed for professional meteorological applications in all climate zones. It delivers reliable data, even in extreme ambient conditions.
Examples of Use:
- Synoptical automatic weather stations of meteorological services
- Weather stations at airports, marinas and onboard ships
- Wind turbine control
- Weather observation for road and traffic control systems
- Mountain weather stations for avalanche and flood warning
- Hydro-meteorological stations
