Fig. 9: Mounting of the radar sensor with inflowing medium
For nozzle mounting, the nozzle should be as short as possible and
its end rounded. This reduces false reflections from the nozzle.
With threaded socket, the antenna end should protrude at least 5 mm
(0.2 in) out of the socket.
ca. 5 mm
Fig. 10: Recommended threaded socket mounting of VEGAPULS C 22
If the reflective properties of the medium are good, you can mount
VEGAPULS C 22 on sockets longer than the antenna. The socket end
should be smooth and burr-free, if possible also rounded.
Note:
When mounting on longer nozzles, we recommend carrying out a
false signal suppression (see chapter "
Parameter adjustment
").
You will find recommended values for socket heights in the following
illustration or the table. The values come from typical applications.
Deviating from the proposed dimensions, also longer sockets are
possible, however the local conditions must be taken into account.
