1. General information
The pressure gauge described in the operating instructions has
been designed and manufactured using state-of-the-art technology.
All components are subject to stringent quality and environmental
criteria during production. Our management systems are certied to
ISO 9001 and ISO 14001.
These operating instructions contain important information on
handling the pressure gauge. Working safely requires that all safety
instructions and work instructions are observed.
Observe the relevant local accident prevention regulations and
general safety regulations for the instrument‘s range of use.
The operating instructions are part of the product and must be kept
in the immediate vicinity of the instrument and readily accessible to
skilled personnel at any time.
Skilled personnel must have carefully read and understood the
operating instructions, prior to beginning any work.
The manufacturer’s liability is void in the case of any damage
caused by using the product contrary to its intended use,
non-compliance with these operating instructions, assignment of
insuciently qualied skilled personnel or unauthorised modica-
tions to the pressure gauge.
The general terms and conditions, contained in the sales documen-
tation, shall apply.
Subject to technical modications.

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 of the materials under pressure with the
medium must be checked!

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.

Permissible medium temperature
The permissible medium temperature not only depends on the instru-
ment design, but also on the ignition temperature of the surrounding
gases, vapours or dusts. Both aspects have to be taken into account.
Potentially explosive gas atmosphere

or vapour)
Maximum permissible medium temperature
(in the measuring system)
Models 232, PG23CP
(dry gauges)
Models 233, PG23LT, PG23CP
(liquid-lled gauges)
T6 (T > 85 °C) +70 °C +70 °C
T5 (T > 100 °C) +85 °C +85 °C
T4 (T > 135 °C) +120 °C +100 °C
T3 (T > 200 °C) +185 °C +100 °C
T2 (T > 300 °C) +200 °C +100 °C
T1 (T > 450 °C) +200 °C +100 °C
Hazardous dust atmosphere
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
of dust
Maximum permissible medium temperature
(in the measuring system)
Dust cloud: TCloud < 2/3 TCloud
Dust layer: TLayer < TLayer − 75 K − (Reduction depending on the layer
thickness)
The permissible maximum medium temperature must not exceed the
lowest determined value, even in case of a malfunction.

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.
