Overview
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.
Benefits
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.
