Aerodynamic calibration for multi-hole probes

Aeroprobe provides aerodynamic probe calibration services to maintain the measurement accuracy and reliability of multi-hole probes. During regular use, small changes to the geometry of the probe tip can occur due to handling, wear or the accumulation of residue from the measured flow.

Even minor changes can affect the pressure distribution across the probe tip. This influences the relationship between measured pressures, flow velocity and flow direction, potentially reducing measurement accuracy.

Aerodynamic recalibration establishes an updated calibration for the probe's current condition, helping restore the specified measurement performance.

Why regular probe recalibration matters

Multi-hole probes are used in applications where accurate flow measurements are required, including wind tunnel testing, turbomachinery research and aerodynamic development.

To maintain reliable results, Aeroprobe recommends recalibration every 12 to 24 months, depending on how frequently the probe is used and the conditions in which it operates.

Regular recalibration helps engineers maintain confidence in measurement data, compare results between test campaigns and identify changes in probe performance.

NIST-traceable aerodynamic calibration

Aeroprobe's aerodynamic calibration measurements are traceable to the National Institute of Standards and Technology (NIST), the national metrology institute of the United States.

Traceability is established through a documented, unbroken chain of calibrations connecting the measurement instruments to recognised standards.

To obtain Aeroprobe's NIST-traceable recalibration documentation, multi-hole probes must be returned to Aeroprobe for calibration.

When should a multi-hole probe be recalibrated?

Recalibration is recommended as part of routine probe maintenance. It is also advisable when a probe has experienced significant handling, possible tip damage or contamination that may affect its aerodynamic characteristics.

The appropriate recalibration schedule depends on the measurement application, operating conditions and accuracy requirements.
