diaphragm for model 700.02).
and p2 are given in the ⊕ and ⊖ measuring chambers, separated

GB
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 applications where no magnetic particles are involved.

5. Options and accessories
In processes with oating particles model 700.02 should be used.
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.

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).
The installation of the dierential pressure gauge is made following the installation
recommendations for pressure gauges in accordance with EN 837-2 /7.

■
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.

7. Commissioning, operation
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.

7. Commissioning, operation
Switch point adjustment
Preference should be given to setting the switch point before installing the
measuring instrument. The necessary test path is generated manually (e.g. by
means of an antimagnetic screwdriver).
Manual test path generation
Plus media chamber
antimagnetic
The switch point can also be set in a pressurised condition after installation. The
switch points are set at the factory when the set points are given.
The switch point is adjusted by turning the contact adjustment screws on the
outside of the reed case.
Anticlockwise rotation:
Switch point can be moved in the direction of the
start of the measuring range
Clockwise rotation:
Switch point can be moved in the direction of the
end of the measuring range
GB
Zero point check
In general, the zero point should only be checked and adjusted at zero pressure.
The system fastening lug on the back of the case can be easily slackened o for
zero point correction of the pressure gauge. Now the zero point can be readjusted
by moving the measuring system to the right or left. After this has been done the
measuring system is to be secured again with the mounting screw (recommended
tightening torque of the mounting screw 1.3 Nm).

8. Maintenance and cleaning
8.1 Maintenance
The instruments are maintenance-free.
GB
The dierential pressure gauges with piston oer long service life provided they
are handled and operated properly.
Checks should be carried out on a regular basis to ensure the measuring
accuracy of the pressure gauge.
Repairs must only be carried out by the manufacturer or appropriately qualied
skilled personnel.
8.2 Cleaning
CAUTION!
■
Clean the pressure gauge with a moist cloth.
■
Wash or clean the dismounted pressure gauge before returning it, in order to protect persons and the environment from
exposure to residual media.
9. Dismounting and disposal
WARNING!
Residual media in dismounted pressure gauges can result in a
risk to persons, the environment and equipment. Take sucient
precautionary measures.
9.1 Dismounting
Only disconnect the pressure gauge once the system has been depressurised!
9.2 Disposal
Incorrect disposal can put the environment at risk.
Dispose of instrument components and packaging materials in an
environmentally compatible way and in accordance with the country-specic
waste disposal regulations.
