Marking of the polarisation direction

When the sensor is mounted on a bypass tube, the distance from
VEGAPULS

66 to the upper tube connection should be approx.

500 mm (19.69 in) or more. In case of extremely rough tube inner
walls, you should use an inserted tube (tube in tube) or a radar sensor
with tube antenna.

Information:
With VEGAPULS 66 in flange version, the polarisation plane is always
in the center between two flange holes.
