Split-fiber probes may substitute for X-array probes in cases where optimum spatial resolution is required, or when the flow vector varies between ±90°.
Used in free-stream applications. The probe is intended for radial operation for example between compressor guide vanes. The probe has the sensor parallel with the probe axis. The probe thus measures the U-W components. Mounts with the probe axis perpendicular to the main flow and rotated, so that the predominant flow vector is in the prong plane and attacks the fiber under 90°.
