|Measurements of temperature induced effects are performed in a climate wind tunnel. |
The whole wind tunnel is placed in an insulated and temperature-controlled chamber. Therefore, temperature induced effects on the whole anemometer can be measured rather than rely on simple assumptions (e. g. for mechanical anemometers temperature is only influencing bearing friction).
|For the standard procedure the measurement is performed at an air velocity of about 4 m/s to 15.5 m/s with 2 m/s increments. The air temperature is varied from -20 °C up to +40 °C. The measurements are performed at ambient pressure and normally with temperature increments of 5 °C.|
|On customer request the measurements can also be performed for a reduced temperature range and for a different increment size.|
