Calibration wind tunnels
All of our wind tunnels are of the Göttingen-type (closed circuit, total length 38m). Measurements can be performed using both open and closed test sections. The test section measures 1m x 1m x 1.8m, and is ideal for the precise measurement of wind measurement sensors.
Contraction Ratio: 5,5
Turbulence Intensity: >0.2 %
Maximum Velocity: 20 m/s
Electrical Power: 11 kW
In full accordance with IEC 61400-50-1:2022, previously IEC 61400-12-1:2017
This wind tunnel serves the German national metrology institute (Physikalisch-Technische Bundesanstalt – PTB) as a comparison and reference channel for the unit "m/s". In other words: In this wind tunnel, a PTB transfer standard is installed to represent the physical unit "meters per second" for air flows. In addition, PTB regularly conducts comparison measurements for national and international interlaboratory comparisons.
