Fig. 13: VEGAPULS 63 in a bypass tube. The polarisation marking on the
process fitting must be in one plane with the tube holes or the tube connection
openings.
1 Marking of the polarisation direction
W hen the sensor is mounted on a bypass tube, the distance from
VEGAPULS 63 to the upper tube connection should be approx.
300 mm (11.81 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:
W
ith VEGAPULS 63 in flange version, the polarisation plane is always
in the center between two flange holes.
