The measuring range of VEGAPULS 64 begins physically at the end
of the antenna. The min./max. adjustment, however, begins at the
reference plane. The reference plane is different depending on the
sensor version.
•
Plastic horn antenna: The reference plane is the sealing surface
on the lower edge
•
Thread with integrated horn antenna: The reference plane is
the sealing surface at the bottom of the hexagon
•
Flange with encapsulated antenna system: The reference
plane is the lower edge of the flange plating
•
Hygienic fittings: The reference plane is the highest contact point
between sensor process fitting and welded socket
The following graphic shows the position of the reference plane with
different sensor versions.
