2.2 Description

These pressure gauges with inductive

contact(s) have been designed speci-

cally for applications in hazardous areas.

WIKA manufactures and qualies these instruments following EN 837 (gauge pressure),

DIN 16002 (absolute pressure), DIN 16003 (dierential pressure) and DIN 16085 (switch

contacts) in the versions “S1” and “S3”.

Version “S1” per EN 837

This version is designed with a blow-out device at the case.

Safety version “S3” per EN 837

This version is made up of laminated safety glass, a solid bae wall between measuring

system and dial and a blow-out back. In the event of a failure, the operator is protected at the

front side, as media or components can only be ejected via the back of the case.

Switch contact model 831

The built-in electrical inductive contacts are non-contact slot-type inductive proximity

sensors, which are powered from switching ampliers with certied intrinsically safe circuits.

On exceeding the adjustable limit values, their output circuits are either opened or closed.

3. Safety

3.1 Explanation of symbols

WARNING!

... indicates a potentially dangerous situation that can result in serious injury or

death, if not avoided.

CAUTION!

... indicates a potentially dangerous situation that can result in light injuries or

damage to property or the environment, if not avoided.

DANGER!

... identies hazards caused by electrical power. Should the safety instructions

not be observed, there is a risk of serious or fatal injury.

WARNING!

... indicates a potentially dangerous situation in the hazardous area that results

in serious injury or death, if not avoided.

WARNING!

... indicates a potentially dangerous situation that can result in burns, caused by

hot surfaces or liquids, if not avoided.

Information

... points out useful tips, recommendations and information for ecient and

trouble-free operation.

3.2 Intended use

These instruments are used to control process values and to monitor plants in industrial

applications.The contact pressure gauge, with up to 3 integrated model 831 inductive

contacts, displays the process pressure on site and opens/closes circuits at dened

pressure values.

The instrument oers many application possibilities for gaseous and liquid aggressive media

that are not highly viscous or crystallising.

Only use the instrument in applications that lie within its technical performance limits (e.g.

temperature limits, material compatibility, ...).

→ For performance limits see chapter 9 “Specications”.

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.

3. Safety

3.3 Improper use

WARNING!

Injuries through improper use

Improper use of the instrument can lead to hazardous situations and injuries.

▶

Refrain from unauthorised modications to the instrument.

▶

Do not use the instrument with abrasive or viscous media.

Exceptions are diaphragm pressure gauges (models PGS43 and 432.56)

with specially coated diaphragms (abrasive) or versions with open connect-

ing anges (viscous).

Any use beyond or dierent to the intended use is considered as improper use.

3.4 Responsibility of the operator

The instrument is used in the industrial sector. The operator is therefore responsible for legal

obligations regarding safety at work.

The safety instructions within these operating instructions, as well as the safety, accident

prevention and environmental protection regulations for the application area must be

maintained.

The operator is obliged to maintain the product label in a legible condition.

To ensure safe working on the instrument, the operating company must ensure

that suitable rst-aid equipment is available and aid is provided whenever required.

that the operating personnel are regularly instructed in all topics regarding work safety,

rst aid and environmental protection and know the operating instructions and in particu-

lar, the safety instructions contained therein.

that the instrument is suitable for the particular application in accordance with its intended

use.

that personal protective equipment is available.

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.

Do not dispose of with household waste. Ensure a proper disposal in accord-

ance with national regulations.

3.8 Ex marking

DANGER!

Danger to life due to loss of explosion protection

Non-observance of these instructions and their contents may result in the loss of

explosion protection.

▶

Observe the safety instructions in this chapter and further explosion protec-

tion instructions in these operating instructions.

▶

Observe the information given in the applicable type examination certi-

cate and the relevant country-specic regulations for installation and use in

3.9 Specifications and temperature limits

Ingress protection per IEC/EN 60529

For information on the ingress protection of the respective instrument, see chapter

9 “Specications”. For the IECEx assessment, IP20 ingress protection was assumed.

Permissible temperature range

For determining the maximum temperature at the instrument, besides the medium

temperature also other inuences such as the ambient temperature and, if applicable, the

solar irradiation must be taken into account.

The installation should be made in such a way that the temperature range of the instrument,

also considering the eects of convection and thermal radiation, neither exceeds nor falls

below the permissible limits.

The permissible temperature ranges of the contact models must not be exceeded at the

instrument either. If necessary, measures for cooling (e.g. syphon, instrumentation valve,

diaphragm seal etc.) have to be taken.

Compliance with the permissible temperature range during operation must be ensured by

the operator by means of temperature measurement(s) at “T-Ref” within the shown hatched

area(s).
