VEGAMIP R62 • Receiving unit
41911-EN-200522
Metric threads
In the case of instrument housings with metric thread, the cable
glands are screwed in at the factory. They are sealed with plastic
plugs as transport protection.
You have to remove these plugs before electrical connection.
NPT thread
In the case of instrument housings with self-sealing NPT threads, it is
not possible to have the cable entries screwed in at the factory. The
free openings for the cable glands are therefore covered with red dust
protection caps as transport protection. The dust protection caps do
not provide sufficient protection against moisture.
Prior to setup you have to replace these protective caps with ap-
proved cable glands or close the openings with suitable blind plugs.
4.2 Mounting instructions
If possible, install VEGAMIP 62 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.

The VEGAMIP 62 requires a minimum medium thickness to detect
different products.
Dependent on the medium there will be a respective medium thick-
ness.
The properties of the medium are also dependent on the granulation
size, the bulk density and the moisture content.

dium:
