2. Safety
WARNING!
Before installation, commissioning and operation, ensure
that the appropriate pressure gauge 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 2.5 “Labelling /
safety marks”
Volume of wetted parts: < 0.1 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.

2. Safety
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 perfor-
mance limits (e.g. max. ambient temperature, material compatibility, ...).
→ For performance limits see chapter 3 “Specications”.

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 analysis. The responsibility for classication of zones
lies with the plant operator and not the manufacturer/supplier of the
equipment.
These ignition sources must be taken into account for the instrument:
1. Hot surfaces
The surface of the instrument can heat up due to the temperature of
the process medium.This depends on the installation situation and
must be taken into account by the operator.
2. Mechanically generated sparks
Mechanically generated sparks are a potential ignition source. If the
materials used exceed a total mass percentage of 7.5 % magnesium,
titanium and zirconium, the operator must take appropriate protective
measures.

14375375.02 06/2020 EN/DE/FR/ES
3. Static electricity
- To avoid electrostatic charging, the instrument must be included in
the equipotential bonding of the system.This can be done via the
process connection or other suitable measures.
- The instrument can optionally contain components with a non-con-
ductive surface coating or lining. In such cases, the operator must
take appropriate measures to prevent electrostatic charging.
- Metal components of the instruments (e.g.TAG plates) must be
included in the equipotential bonding of the system during installa-
tion and operation.
4. Adiabaticcompressionandshockwaves
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.
5. Chemical reactions
The operator must ensure that chemical reactions between wetted
parts, process medium and environment are excluded.The materi-
als used can be found in the instrument marking. See chapter 2.5
“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.
2. Safety

EN
WIKA operating instructions pressure gauge, model 2 per ATEX10
14375375.02 06/2020 EN/DE/FR/ES
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).
2.3 Personnelqualication
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 described below.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their
technical 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.
2.4 Safety instructions for hazardous locations
