V200A-UMB | Wind/flow
Description:
V200A-Ultrasonic Wind Sensor, plastic housing and 20W-heaterSupplementary description:
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.
