WARNING!
Before installation, commissioning and operation, ensure that the
appropriate instrument has been selected in terms of measuring
range, design and specic measuring conditions.
Check the compatibility with the medium of the materials subjected
to pressure!
In order to guarantee the measurement accuracy and long-term
stability specied, the corresponding load limits must be observed.
Non-observance can result in serious injury and/or damage to
property.
Further important safety instructions can be found in the individual
chapters of these operating instructions.
2.1 Intended use
These instruments are used for measuring pressure in hazardous areas of indust-
rial applications.
Suitability for use in accordance with model ID
See chapter 1 for the assignment of model ID to model.
Application Model
ID
A B
For gaseous and liquid aggressive media that are not highly viscous or crystalli-
sing, also in aggressive environments

Pump monitoring and control  
Filter monitoring  
Level measurement on closed vessels  
For measuring locations with a high dierential pressure overload and/or high
working pressures (static pressures)

For gaseous, liquid, contaminated, viscous and aggressive media, also in ag-
gressive environments

The instrument has been designed and built solely for the intended use described
here, and may only be used accordingly.

2. Safety
The manufacturer shall not be liable for claims of any type based on operation
contrary to the intended use.
2.2 Responsibility of the operator
The legibility of the marking must be observed during time in use but at least
during inspection periods of three years. If any harm of the legibility is found
please contact the manufacturer to renew the marking.
For the safety of the system, the operator is obliged to carry out an ignition source
and ignition hazard analysis. Refer to chapter 2.3 “Ignition hazards”.
The responsibility for classication of zones lies with the plant manager and not
the manufacturer/supplier of the equipment.

The materials used can be found in the instrument marking. See chapter
2.6 “Labelling / Safety marks”.
On the wetted parts of the instrument, small residual amounts of the
adjustment medium (e.g. compressed air, water, oil) can adhere from
production.With increased requirements for technical cleanliness,
suitability for the application must be checked by the operator before
commissioning.
Liquid media with the property of changing the volume during solidi-
cation can damage the measuring system (e.g. water if it falls below
the freezing point).
2.4 Personnel qualification
WARNING!
Risk of injury should qualication be insucient!
Improper handling can result in considerable injury and damage to
property.
The activities described in these operating instructions may only be
carried out by skilled personnel who have the qualications descri-
bed below.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their techni-
cal training, knowledge of measurement and control technology and on their
experience and knowledge of country-specic regulations, current standards
and directives, are capable of carrying out the work described and independently
recognising potential hazards.

2.5 Special hazards
WARNING!
For hazardous media such as oxygen, acetylene, ammable or
toxic gases or liquids, and refrigeration plants, compressors, etc., in
addition to all standard regulations, the appropriate existing codes or
regulations must also be followed.
For further important safety instructions see chapter 2.7 “Special conditions for
safe use (X conditions)”.
WARNING!
Residual media in dismounted instruments can result in a risk to
persons, the environment and equipment.
Take sucient precautionary measures.
