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.
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 specic 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 sucient
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 prole 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.

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 inuence of convection and heat radiation, no deviation above
or below the permissible ambient and medium temperatures can occur.The
inuence 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.
