General instructions

Protect your instrument against moisture ingress through the following
measures:
•
Use the recommended cable (see chapter "Connecting to power
supply")
•
Tighten the cable gland
•
Loop the connection cable downward in front of the cable gland
This applies particularly to:
•
Outdoor mounting
•
Installations in areas where high humidity is expected (e.g. through
cleaning processes)
•
Installations on cooled or heated vessels
Make sure that all parts of the instrument exposed to the process are
suitable for the existing process conditions.
These are mainly:
•
Active measuring component
•
Process fitting
•
Process seal
Process conditions are particularly:
•
Process pressure
•
Process temperature
•
Chemical properties of the medium
•
Abrasion and mechanical influences
You can find detailed information on the process conditions in chapter
"Technical data" as well as on the type label.
As a standard feature, the VEGAPULS 64 is separate from the pro-
cess through its plastic antenna encapsulation.
Optionally, the instrument is available with a Second Line of Defense
(SLOD), a second process separation. It is located as gas-tight
leadthrough between the process component and the electronics.
This means additional safety against penetration of the medium fron
the process into the instrument.

Mounting versions, plastic horn antenna

The optional mounting strap allows simple mounting of the instrument
on a wall, ceiling or boom. Especially in the case of open vessels, this
is a simple and effective way to align the sensor to the surface of the
bulk solid material.
The following versions are available:
•
Length 300 mm
•
Length 170 mm
