4. Installation and commissioning
To acchieve a correct sealing of pressure connections suitable sealing
rings, sealing washers or WIKA profile seals have to be used. In order
to get the pressure instrument into an orientation that allows to read the
on-site indicator the best, a connector with an adjusting nut or an union
nut is recommended. When mounting and dismounting it is not allowed to
tighten the pressure instruments by using the housing, but on the spanner
flats of the stem, only.
Installation with
spanner
If the pressure instrument is positioned lower than the pressure test
connection, the tailpipe has to be rinsed thoroughly prior to fitting the
gauge to remove all foreign substances.
Once the pressure and electrical connections have been made, the
transmitter is ready for immediate use.
Before dismounting the pressure instrument the measuring element has to
be depressurized. Eventually the stress of the pipe has to be relieved.
Residual pressure medium remaining within the pressure
element may cause harm to men, facilities and environment.
Therefore sufficient precautionary measures have to be
taken.
Pressure connector
In accordance with the general technical regulations for pressure gauges
(e.g. EN 837-2 „Selection and installation recommendations for pressure
gauges").
