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 certied 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
insuciently qualied skilled personnel or unauthorised modica-
tions to the pressure gauge.
The general terms and conditions, contained in the sales documen-
tation, shall apply.
Subject to technical modications.

WARNING!
Before installation, commissioning and operation, ensure
that the appropriate pressure gauge has been selected in
terms of measuring range, design and specic 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 specied, 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
hazardous 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 qualication
WARNING!
Risk of injury should qualication be insucient!
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 qualications 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-specic 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 EC-type examination certicate are
followed.
Pressure gauges must be earthed via the process
connection!
Specications
Permissible temperatures
Ambient: Model 232/262 -40 ... +60 °C
Model 233/263 -20 ... +60 °C (glycerine lling)
-40 ... +60 °C (silicone oil lling)
Medium: The permissible medium temperature not only depends on
the instrument design, but also on the ignition temperature
of the surrounding gases, vapours or dusts. Both aspects
have to be taken into account.
For maximum permissible medium temperatures see table 1.
Attention! In the case of gaseous substances, 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.

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.
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 sucient precautionary measures.
