VEGAPULS 68 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 68 with the flange, e.g. in a bench vice
2 Hold the connection piece (3) with a wrench SW 22 on the
flattenings
3 Unscrew the locknut (2) with SW 36 against the antenna
4 Loosen compression nut (1) with a wrench SW 41 completely in
the direction of the antenna
5 Remove the parabolic antenna (4) axially
6 Mount sensor flange to the adapter flange and clamp it
