VEGAPULS 45 sensor version was espe-
cially developed for measuring tube applica-
tions and is supplied complete with a 27 mm
measuring tube. With a measuring tube
length up to 4 m, this sensor version can be
used, e.g. in existing standpipes.
Note:
VEGAPULS 45 sensors with an integrated
measuring tube are provided with a screwed
process connection or a flange connection.
For sensors with screwed thread as process
connection, make sure that during screwing
in the entire sensor turns, i.e. also the sensor
housing. The sensor housing is fastened with
a clamping connection to the measuring tube.
This sensor housing must not be turned with
respect to measuring tube or even loosened.
Otherwise, the radar signal coupling would
be destroyed and the sensor would no
longer function.
