4 Mounting

4.1 General instructions

Make sure that all parts of the instrument coming in direct contact

with the process, especially the sensor element, process seal and

processtting,aresuitablefortheexistingprocessconditions,such

as process pressure, process temperature as well as the chemical

properties of the medium.

nameplate.

Select an installation position you can easily reach for mounting and

connectingaswellaslaterretrottingofadisplayandadjustment

module. The housing can be rotated by 330° without the use of any

tools. You can also install the display and adjustment module in four

dierentpositions(eachdisplacedby90°).

You can give your instrument additional protection against moisture

penetration by leading the connection cable downward in front of the

cableentry.Rainandcondensationwatercanthusdraino.Thisap-

plies mainly to outdoor mounting as well as installation in areas where

high humidity is expected (e.g. through cleaning processes) or on

cooled or heated vessels.
