2.1 Overview
Series 40 sensors are manufactured in three
basic versions, VEGAPULS 42, VEGAPULS
44 and VEGAPULS 45.
VEGAPULS 42 sensors are characterised by

" NPT thread as process fitting.
These sensors are equipped as standard
versions with a ø 40 mm horn as antenna.
VEGAPULS 44 sensors are characterised by
a DIN or ANSI flanges as process fitting. In
standard version they are manufactured with
DN 50, 80, 100 and 150 as well as with ANSI
2", 3", 4" and 6". The bigger flanges come
equipped with respectively larger antenna
horns (ø 48, 75 and 95 mm).
Generally: The bigger the antenna horn, the
better the focusing characteristics, and the
better the antenna gain. This ensures that
even a weak product echo can be detected
reliably as level echo.
VEGAPULS 45 sensors come completely
equipped with a measuring tube of 4 m
length. These sensors are used in
applications where high accuracy is required
or for liquids with very low dielectric constant
such as e.g. liquid gas.
