Clean and dry air from a pressurised air supply must be supplied for the operation. By connecting the calibrator via USB or Ethernet to a computer running the supporting software, StreamWare, the system is ready to use.
The compact design makes it possible to perform in situ calibrations of probes fixed in e.g. a wind tunnel. Relying on an aerodynamically designed flow section, high-precision transducers and control valves the calibrator generates a free low-turbulence jet that is used as a velocity reference for calibrations. The probe to be calibrated is placed at the jet exit. The unit can be equipped with a pitch-yaw manipulator that allows 2-D and 3-D probes to be rotated for calibration of directional sensitivity.
