In order to guarantee the measuring 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 equipment.
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 within hazard-
ous areas in 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.

2. Safety
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
requirements of the EU-type examination certicate are
followed.
Pressure gauges must be grounded via the process
connection.
Permissible ambient temperature
Model 232/262/PG23CP -40 ... +60 °C (unlled)
Model 233/263/PG23CP -20 ... +60 °C (glycerine lling)
-40 ... +60 °C (silicone oil lling)
Model PG23LT -70 ... +60 °C (silicone oil lling)
Attention! In the case of gaseous media, the temperature may
increase due to compression warming. In these cases it may be neces-
sary to throttle the rate of change of pressure or reduce the permissible
medium temperature.

ment design, but also on the ignition temperature of the surrounding
gases, vapours or dusts. Both aspects have to be taken into account.

For dusts, the procedure specied in ISO/IEC 80079-20-2 for determin-
ing the ignition temperature has to be applied.The ignition temperature
is determined separately for dust clouds and dust layers, respectively.
For dust layers, the ignition temperature depends on the dust layer
thickness per IEC/EN 60079-14.
Ignition temperature

Maximum permissible medium temperature
(in the measuring system)
Dust cloud: TCloud < 2/3 TCloud

Handling of materials
Avoid handling of materials that react dangerously with the materials
used for the instrument, and substances liable to spontaneous
combustion.
Cleaning
Clean the measuring instrument with a moist cloth. Ensure that due to
the cleaning no electrostatic charge will be generated.
2.4 Special hazards
WARNING!
For hazardous media such as oxygen, acetylene, amma-
ble 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.
From pressure gauges which do not correspond to a
safety version per EN 837 highly pressurised media might
leak out through the possibly bursting window in case of a
component failure.
For gaseous media and operating pressures > 25 bar a
pressure gauge with safety version S3 is recommended
per EN 837-2.
For additional important safety instructions see chapter "2.3 Safety
instructions for pressure gauges per ATEX".
WARNING!
Residual media in dismounted pressure gauges can result
in a risk to persons, the environment and equipment.
Take sucient precautionary measures.

6. Commissioning, operation
6. Commissioning, operation
Mechanical connection
In accordance with the general technical regulations for pressure
gauges (e.g. EN 837-2 "Selection and installation recommendations for
pressure gauges").
Pressure gauges must be grounded via the process connection.This is
why electrically conductive sealings should be used at the process
connection. Alternatively, take other measures for grounding.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.
For parallel threads, use at gaskets, lens-type sealing rings or WIKA
prole sealings at the sealing face
 . With tapered threads (e.g. NPT
threads), sealing is made in the threads
 using suitable sealing
material (EN 837-2).
Spanner ats Sealing in the

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.

6. Commissioning, operation
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 suciently stable a measuring instru-
ment support such as a bracket or ange should be used for fastening
(possibly via a exible capillary). If vibrations cannot be avoided by
taking suitable measures during installation, liquid-lled instruments
should be used. Instruments must be protected against coarse dirt and
wide uctuations in ambient temperature.
Installation
Nominal position per EN 837-1 / 9.6.7 Figure 9: 90° ( ⊥ )
Process connection lower mount (LM) or back mount (BM)
After mounting, set the compensating valve (if available) from
CLOSE to OPEN. The version of the vent
valve depends on the model and can deviate
from the illustration!
For outdoor applications, the selected installation location has to
be suitable for the specied ingress protection, so that the pressure
gauge is not exposed to impermissible weather conditions.
In order to avoid any additional heating, the instruments must not be
exposed to direct solar irradiation while in operation!
To ensure that the pressure can be safely vented in the case of
failure instruments with blow-out device or blow-out back must keep
a minimum distance of 20 mm from each object.

Permissible ambient and operating temperatures
When mounting the pressure gauge it must be ensured that, taking into
consideration the inuence of convection and heat radiation, no devia-
tion 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 vibra-
tion.
If necessary, it is possible to isolate the instrument from the mount-
ing point by installing a exible connection line between the measur-
ing point and the pressure gauge and mounting the instrument on a
suitable bracket.
If this is not possible, the following limit values must not be exceeded:
Frequency range < 150 Hz
Acceleration < 0.7 g (7 m/s2)
Filling level testing
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.

7. Maintenance and cleaning
7.1 Maintenance
The instruments are maintenance-free.
The indicator and switching function should be checked once or twice
every year.The gauge must be disconnected from the process to check
with a pressure testing device.
Repairs are only to be carried out by the manufacturer or appropriately
trained skilled personnel.
7.2 Cleaning
CAUTION!
Clean the pressure gauge with a moist cloth.
Wash or clean the dismounted pressure gauge before
returning it, in order to protect personnel and the
environment from exposure to residual media.
8. Dismounting and disposal
WARNING!
Residual media in dismounted pressure gauges can
result in a risk to persons, the environment and equip-
ment.
Take sucient precautionary measures.
8.1 Dismounting
Only disconnect the pressure gauge once the system has been
depressurised!
When dismounting, close the compensating valve (if available).
8.2 Disposal
Incorrect disposal can put the environment at risk. Dispose of instru-
ment components and packaging materials in an environmentally
compatible way and in accordance with the country-specic waste
disposal regulations.
