2. Safety

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

14508917.01 12/2021 EN/DE/FR/ES

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.

2. Safety

WIKA operating instructions pressure gauge model 4 per ATEX8

14508917.01 12/2021 EN/DE/FR/ES

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.
