Ventus-UMB | Ветер
Supplementary description:
Extremely precise and maintenancefree 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 known with traditional "cups and vane". The digital or analog output delivers instantaneous, average, min or max value with flexible measuring rate. The VENTUS is heated in case of critical ambient conditions. Made for cold climates! Recommended for: Wind turbines, marine/ships, meteorology and building automation. The following outputs/protocols are available: NMEA, UMB-ASCII, UMB-Binary, MODBUS (ASCII, RTU), SDI-12, 4...20 mA, 0...10V, 0...20 mA, 2...10V, frequency (analog)
