User Manual

Note:
The radar sensor with rinsing air connection or antenna exte nsion is
provided with a notch on the antenna socket. This notch must
correspond to the marking on the hexagon of the process fitting (the
marking specifies the position of the polarisation level of the radar
signal).

4.3 Mounting preparations - Parabolic antenna
The instrument is also available in versions where the antenna has a
diameter larger than the process fitting (thread, flange). With such
versions the antenna must be disconnected from the process fitting
before mounting. Proceed as follows:
1 Clamp VEGAPULS 62 with the flange, e.g. in a bench vice
2 Hold the connection piece (3) with a wrench (width across flats 22)
on the flattenings
3 Loosen counter nut (2) completely with a wrench (width across
flats 36) in the antenna direction
4 Loosen compression nut (1) completely with a wrench (width
across flats 41) in the antenna direction
5 Remove the parabolic antenna (4) axially
6 Mount sensor flange to the adapter flange and clamp it
7 Check, if the O-ring seal is available on the connection piece and if
it is not damaged.
