4.1 General instructions
The instrument is suitable for standard and extended ambient condi-
tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used
indoors as well as outdoors.
Note:
For safety reasons, the instrument must only be operated within the
permissibleprocessconditions.Youcannddetailedinformationon
the process conditions in chapter " Technical data" of the operating
instructions or on the type label.
Hence make sure before mounting that all parts of the instrument ex-
posed to the process are suitable for the existing process conditions.
These are mainly:
•
Active measuring component
•
Processtting
•
Process seal
Process conditions in particular are:
•
Process pressure
•
Process temperature
•
Chemical properties of the medium
•
Abrasionandmechanicalinuences
Thepermissibleprocesspressurerangeisspeciedby"MWP"(Maxi-
mum Working Pressure) on the type label, see chapter "Structure".
The MWP takes the element of the measuring cell and processing
ttingcombinationwiththeweakestpressureintoconsiderationand
mayappliedpermanently.Thespecicationreferstoareference
temperature of +20 °C (+68 °F). It also applies when a measuring cell
with a higher measuring range than the permissible pressure range of
theprocessttingisinstalledorder-related.
In order to prevent damage to the device, a test pressure may only
exceedthespeciedMWPbrieyby1.5timesatreferencetempera-
ture.Thepressurestageoftheprocessttingaswellastheoverload
resistance of the measuring cell are taken into consideration here
(see chapter "Technical Data").
Inaddition,atemperaturederatingoftheprocesstting,e.g.with
anges,canlimitthepermissibleprocesspressurerangeaccording
to the respective standard.
Protect your instrument against moisture ingress through the following
measures:
•
Use a suitable connection cable (see chapter "Connecting to
power supply")
•
Tighten the cable gland or plug connector
•
When mounting horizontally, rotate the housing so that the cable
gland or plug connector point downward
