Kiel Probe

Kiel Probe

Kiel probes are used to measure the total pressure of a flow with high accuracy over a wide range of flow angles. Unlike a Pitot probe, the Kiel probe’s shroud acts to straighten the incoming flow and remove measurement errors associated with varying flow angles. Kiel probes do not require aerodynamic calibration.

Combination Kiel-Total Air Temperature (TAT) probes are also available to provide pressure and temperature data with one instrument. Additionally, Aeroprobe specializes in the custom design and engineering of Kiel probes for integration into rake geometries and specialized mounting hardware.

While the advantage of a Kiel probe is it’s insensitivity to flow angle, it does not provide a measurement of the flow angle. If simultaneous measurement of flow angle as well as total and static pressure is required, please see our multi-hole probe products.

Images below show examples of standalone Kiel and combination Kiel-Total Air Temperature (TAT) probes.
