General instructions

On instruments with process fitting thread, the hexagon must be tight-
ened with a suitable wrench. For the proper wrench size see chapter
"Dimensions".
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
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.
Protect your instrument against moisture ingress through the following
measures:
•
Use the recommended cable (see chapter "Connecting to power
supply")
•
Tighten the cable gland
•
When mounting horizontally, turn the housing so that the cable
gland points downward
•
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

Mounting instructions

If possible, install VEGAMIP 61 in a position where strong signal
damping by the medium is expected.
Avoid mounting the instrument too close to the vessel wall. Reflec-
tions from the vessel wall or from vessel installation can influence the
switching accuracy.
