Operating Manual V25/09.2019
Ventus / Ventus-X / V200A
Chapter 8 Measurement Output 12
8.4 Wind Speed
Sampling rate 250ms; 1 – 10 seconds
Generation of average value 1 – 60 measurements
Generation of maximum value 1 – 60 measurements based on the internal second
measurement values
Units m/s; km/h; mph; kts
Response threshold 0.1 m/s (metal) or 0.3 m/s (plastics)
Request channels:
Note: In order to transmit the current measurement value the second measurement values are
averaged over the sampling rate.
8.4.1 Wind Gust Speed (WMO Specification)
Sampling Rate 250ms
Generation of Value Highest 3sec average of the last 10min
Request channels:
Note: With extended sampling rates (50ms / 100ms) the evaluation of wind gust is deactivated.
The channels will show status “channel off” (0x36)
8.5 Wind Direction
Sampling rate 250ms; 1 – 10 seconds
Generation of average value 1 – 60 measurements
Generation of maximum value 1 – 60 measurements based on the internal second
measurement values Unit °
Response threshold 0.1 m/s (metal) or 0.3 m/s (plastics)
Request channels:
Note: In order to transmit the current measurement value the second measurement values are
averaged over the sampling rate.
The minimum / maximum wind direction indicates the direction at which the minimum /
maximum wind speed was measured.
The wind gust direction is the vector average of the direction measured during the highest 3sec
speed average of the last 10min.
