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.
Observe the selection and installation recommendations for
pressure gauges in accordance with EN 837-2.
Check the compatibility with the medium of the materials
subjected to pressure!
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
the equipment.
Further important safety instructions can be found in the
individual chapters of these operating instructions.

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 dierential 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 declaration of conformity are followed.
Dierential pressure gauges must be grounded via the process
connection!
Specications
Permissible temperatures
Ambient: 0 … +60 °C
Medium: The permissible medium temperature does not only depend on
the instrument design, but also on the ignition temperature of the
surrounding 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 these cases it may be necessary to throttle the rate
of change of pressure or reduce the permissible medium temperature.

4. Design and function
Description
Pressures p1and p2 are given in the ⊕ and ⊖ measuring chambers, separated
by the magnetic piston under pressure (or magnetic piston and separating
diaphragm for model 700.02).
The dierence in pressure causes an axial movement (deection) of the piston
supported by the measuring range spring.
The deection resulting from this is taken up by a ring magnet found on
the instrument pointer and appropriately displayed. This design combines
the advantages of complete separation of the measuring system and the
indication while eliminating any leakage to the exterior.
For model 700.01 the volume ow from the ⊕ measuring chamber to the ⊖
measuring chamber is minimised by the constructive design and will not interfere
with standard processes.
These instruments are mainly intended for gas/air supply and preparation
applications where no magnetic particles are involved.

7. Commissioning, operation
Mechanical connection
The installation of the dierential pressure gauge is made following the installation
recommendations for pressure gauges in accordance with EN 837-2 /7.
Mounting of the process connection according to axed symbols ⊕ and ⊖
⊕ high pressure, ⊖ low pressure
■
Hold against the connection pieces in the case of installation by means of
17 mm screw spanner (installation without holding against the connection
pieces may cause thet measuring system to get loose).
■
The maximum permissible medium/ambient temperature must not be
exceeded.
■
Prior to the installation of the pressure gauge, clean the measuring lines
thoroughly by tapping and blowing or rinsing.
■
Mount and operate the measuring instruments free from vibration.
■
Protect measuring instruments from contamination and high temperature
changes.
To avoid foreign matter in the measuring system and the resulting damage to the
system, the pressure gauge must be mounted above the connector. For measuring
media containing suspended particles model 700.02 should be used.
6. Transport, packaging and storage / 7. Commissioning ...
6. Transport, packaging and storage
6.1 Transport
Check the dierential pressure gauge for any damage that may have been
caused by transport. Obvious damage must be reported immediately.
6.2 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).
6.3 Storage
Permissible conditions at the place of storage
Storage temperature: -20 ... +70 °C (optional: -40 … +70 °C)
