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 pressure gauges are used for measuring pressure in hazardous areas of
industrial applications.
ClassicationperEuropeanpressureequipmentdirective
Instrument type: Pressure accessory without safety function
Media: Liquid or gaseous, group 1 (dangerous)
Maximum permissible pressure PS, see chapter 2.6 “Labelling / safety marks”
Volume of wetted parts: 1 l
The instrument must only be used with media which are not harmful to the wetted
parts over the entire operating range of the instrument. Any change in the state of
the matter or any decomposition of unstable media is not permitted.
Only use the instrument in applications that lie within its technical performance
limits (e.g. max. ambient temperature, material compatibility, ...).
→ For performance limits see chapter 3 “Specications”.
Suitability for use
Process industry: Chemical industry, petrochemical industry, oil and gas,
power generation, water and wastewater technology, machine building and
general plant construction
For measuring locations with increased overload

2. Safety
With case lling for high dynamic pressure loads and vibrations
(model 433.50)
For gaseous, liquid and aggressive media, also in aggressive environments
With open connecting ange also suitable for contaminated and viscous media
Increased safety requirements for personal protection with case of safety level
“S3” per EN 837
The instrument has been designed and built solely for the intended use described
here, and may only be used accordingly.
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.
