2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the
appropriate instrument has been selected in terms of measuring
range, design and specic 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 specied, the corresponding load limits must be observed.
Non-observance can result in serious injury and/or damage to the
equipment.
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 absolute pressure in hazardous areas
of industrial applications.
They are particularly used for the monitoring of vacuum pumps, the control of
vacuum packing machines, the monitoring of condensation pressures and the
determination of vapour pressure in liquids.
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 Personnel qualication
WARNING!
Risk of injury should qualication be insucient!
Improper handling can result in considerable injury and damage to
equipment.
The activities described in these operating instructions may only
be carried out by skilled personnel who have the qualications
described below.

2. Safety
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-specic regulations, current standards
and directives, are capable of carrying out the work described and independently
recognising potential hazards.
2.3 Safety instructions for pressure gauges per ATEX
WARNING!
Non-observance of these instructions and their contents may result
in the loss of explosion protection.
WARNING!
It is imperative that the application conditions and safety require-
ments of the EC-type examination certicate are followed.
▶
Instruments must be grounded via the process connection.
Permissible ambient temperature
-20 ... +60 °C
-40 ... +60 °C (optional, only for silicone oil lling)
Attention! With gaseous media, the temperature may increase as a result of
compression warming. In these cases it may be necessary to throttle the rate of
change of pressure or reduce the permissible medium temperature.
Permissible medium temperature
-20 ... +100 °C
-40 ... +200 °C (optional, only for unlled gauges)
The permissible medium temperature does not only depend on the instrument
design, but also on the ignition temperature of the surrounding gases, vapours or
dusts. Both aspects have to be taken into account.
Maximum surface temperature
The surface temperature of the instruments mainly depends on the medium
temperature of the application. For determining the maximum surface tempera-
ture, besides the medium temperature also other inuences such as the ambient
temperature and, if applicable, the solar irradiation must be taken into account.

Hazardous dust atmosphere
For dusts, the procedure specied in ISO/IEC 80079-20-2 for determining the
ignition temperature has to be applied.The ignition temperature is determined
separately for dust clouds and dust layers, respectively. For dust layers, the
ignition temperature depends on the dust layer thickness per IEC/EN 60079-14.
Ignition temperature
of dust
Maximum permissible medium temperature
(in the measuring system)
Dust cloud: Tcloud < 2/3 Tcloud
Dust layer: Tlayer < Tlayer − 75 K − (reduction depending on the layer thickness)
The permissible maximum medium temperature must not exceed the lowest
determined value, even in case of a malfunction.
Explosive atmosphere consisting of hybrid mixtures
The instruments must not be used in areas in which an atmosphere consisting of
explosive hybrid mixtures (dusts mixed with gases) can occur.
2.4 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 additional important safety instructions see chapter 2.3 “Safety instructions
for pressure gauges per ATEX”.

2.6. Special conditions for safe use (X conditions)
Pressure surges must be avoided at all costs. Open the shut-o valves slowly.
Temperature increases due to compression warming absolutely must be taken
into account. In these cases it may be necessary to throttle the rate of change
of pressure or reduce the permissible medium temperature.
The end user must ensure that the instrument is connected to the equipotential
bonding of the end-use application via the process connection.
Avoid handling substances that might react dangerously with the materials of
the instrument.
Avoid handling substances that are liable to spontaneous combustion.

4. Design and function
Description
Nominal size 100 and 160 mm
The instruments measure the pressure by means of resilient diaphragm
measuring elements.The reference point is absolute pressure “zero”.
In addition, the enclosing components of
models 53X.30.1X0 and 53X.36.1X0 also
meet the requirements of EN 837-1, relating to
safety pressure gauges with a solid bae wall
(code S3).
The diaphragm (1) separates the media
chamber (3) and the reference pressure
chamber (2) with absolute pressure zero
Pressure dierential between media chamber
(3) and reference pressure chamber (2) will
deect the diaphragm (1)
In case of an overpressure overload the
pressure element will be protected by a
contoured metal bolster
The deection is transferred from the pressure
chambers through bellows or corrugated
tubes (4), transmitted to the movement via the link (5) and indicated.
Scope of delivery
Cross-check scope of delivery with delivery note.
5. Transport, packaging and storage
5.1 Transport
Check the instrument for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g.
change in installation site, sending for repair).
