regulations for the dierential pressure gauge's range of use.
The operating instructions are part of the product and must be kept in the
immediate vicinity of the pressure gauge 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

2. Safety
2. Safety
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.

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 specied, 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.
2.1 Intended use

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.

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 dierence in pressure causes an axial movement (deection) of the piston
supported by the compression spring.
The deection 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 appli-
cations where no magnetic particles are involved.

Scope of delivery
Cross-check the scope of delivery with the delivery note.
5. Options and accessories
5.1 Mounting ange (only for model 700.01, see left illustration)
May be retrotted on site as required.
Alignment of the front bezel (A) by means of the stamped cams to the grooves
found on the case circumference. Push front bezel on the case until it snaps into
position.
5.2 Minimum or maximum drag pointer (see illustrations)
The drag pointer (B) serves to monitor and control the miniumum or maximum
occurring dierential pressure.
5.3 Reed contact model 851.3 and 851.3.3 (see illustrations)
May be retrotted and adjusted on site as required.
Fastening is by means of two screws (D) integrated in the reed case (C) on the
display case with the pertinent female thread.

7. Commissioning, operation
Mechanical connection
The installation of the dierential 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 axed 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
5.1 Transport
Check 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)

If the line to the gauge is not rigid enough for a vibration-free installation, the gauge
should be mounted by means of appropriate fastening elements for wall mounting,
or, if necessary, with a capillary.
