X-probe, with right-angled prongs for radial operation.
The probe are intended for radial operation in pipes or ducts. The probe has the sensor plane perpendicular to the probe axis. It measures the U-W components. Mounts with the probe axis perpendicular to the main flow and rotated, so that the predominant flow vector attacks the two wires under 45°.
Has a heavy coating, can therefore be used in conducting liquids.
