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.

The compatibility with the medium of the materials subjected to

pressure must be checked!

n order to guarantee the measuring accuracy and long-term

stability specied, the corresponding load limits must be observed.

Serious injuries and/or damage can occur should these not be

observed.

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.

The pressure gauge 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 qualication

WARNING!

Risk of injury should qualication be insucient!

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

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.

2.3 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 certicate are

followed.

Pressure gauges must be earthed via the process connection!

Technical data

Operating temperature

Ambient: -20 ... +60 °C (optional: -40 … +60 °C)

Medium: The permissible medium temperature does not only depend on the

instrument design, but also on the ignition temperature of the surroun-

ding gases, vapours or dust. Both aspects have to be taken into account.

For permissible maximum medium temperatures see table 1.

Attention! With gaseous substances, the temperature may increase as a result

of compression warming. In such cases the rate of change of pressure must be

slowed down or the permissible medium temperature must be reduced.

2.4 Special hazards

WARNING!

Dangerous pressure media such as Oxygen, Acetylene, amma-

ble gases or liquids, toxic gases or liquids as well as for refrigera-

tion plants or compressors requires attention above the standard

regulations. Here the specic safety codes or regulations must be

considered.

For additional important safety instructions see chapter "2.3 Safety instructions for

gauges per ATEX".

WARNING!

Residual media in dismounted pressure gauges may result in a

risk to people, the environment and the system. Take sucient

precautionary measures.

4. Design and function

Description

Nominal size 63, 100 and 160 mm

The gauges measure the pressure by means of resilient capsule pressure

elements

The measuring characteristics are in accordance with the EN 837-3 standard

Scope of delivery

Cross-check scope of delivery with delivery note.

5. Transport, packaging and storage

5.1 Transport

Check pressure gauge 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).

5.3 Storage

Permissible conditions at the place of storage

Storage temperature: -20 ... +70 °C (optional: -40 … +70 °C)

6. Commissioning, operation

Mechanical connection

In accordance with the general technical regulations for pressure gauges (i.e.

EN 837-2 "Selection and installation recommendations for pressure gauges").

When screwing gauges in, the force required for this must not be applied through

the case, but rather through the spanner ats (using a suitable tool) provided for

this purpose on the square shaft of standard connections.

Correct sealing of pressure gauge connections with parallel threads must be

made using suitable sealing rings, sealing washers or WIKA prole seals. The

sealing of tapered threads (e.g. NPT threads) is made by providing the thread ,

with additional sealing material such as, for example, PTFE tape (EN 837-2).

The torque depends on the seal used. Connecting the gauge using a clamp

socket or a union nut is recommended, so that it is easier to orientate the gauge

correctly. When a blow-out device is tted to a pressure gauge, it must be

protected against being blocked by debris and dirt.

Requirements for the installation point

If the measuring point is not adequately stable a measuring instrument support

such as a bracket or ange should be used for fastening (and possibly via a

exible capillary line). If the pressure gauge is exposed to vibration or pulsating

pressure or both, then a liquid lled pressure gauge may provide considerably

better performance and readability. Instruments should be protected against

coarse dirt and wide uctuations in ambient temperature.

WIKA operating instructions pressure gauge model 6 per ATEX

6. Commissioning, operation

Installation

Nominal position per EN 837-3 / 9.6.7 Figure 9: 90° ( ⊥)

Process connection: lower mount (LM) or model 63X.50 back mount (BM)

After mounting, set the compensating valve (if available)

from CLOSE to OPEN.

In order to avoid any additional heating, the instruments must not be exposed

to direct solar irradiation while in operation!

Admissible ambient and working temperatures

When mounting the pressure gauge it must be ensured that, taking into

consideration the inuence of convection and heat radiation, no deviation above

or below the permissible ambient and medium temperatures can occur.The

inuence of temperature on the display accuracy must be observed.

Permissible vibration load at the installation site

The instruments should always be installed in locations free from vibration.

If necessary, it is possible to isolate the instrument from the mounting point

by installing a exible connection line between the measuring point and the

pressure gauge and mounting the instrument on a suitable bracket.

Liquid-lled gauges (model 633.50) may only be used within the following

limits:

Frequency range < 150 Hz and

Acceleration < 0.5 g (5 m/s2)

The liquid lling must be checked on a regular basis.

The liquid level must not drop below 75 % of the gauge diameter.

Commissioning

During the commissioning process pressure surges must be avoided at all costs.

Open the shut-o valves slowly.
