4. Design and function ... 6. Commissioning, operation
Design and operating principle
The dierential pressure transmitter has a ceramic dierential pressure sensor
with thick lm technology, which works according to the principle of a Wheatstone bridge. The dierential pressure deects the ceramic diaphragm, thereby
changing the strain gauge signal, which is amplied to a standard current output
signal by the integrated electronics. The sensor is mounted between the two case
halves and sealed by O-rings. The sensor signal is transmitted, free of interfe-
rence, to the printed circuit board via ex cables. The transmitter is electrically
connected by means of a 3-wire cable which is led to the room for service
connections through a protective tube. The instrument has 2 lugs for mounting.
The dierential pressure transmitter is both factory calibrated and temperature
compensated.
Scope of delivery
Cross-check scope of delivery with delivery note.
5. Transport, packaging and storage
5.1 Transport
Check transmitter for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
5.2 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).
GB
5.3 Storage
Permissible conditions at the place of storage:
Storage temperature: -20 ... +50 °C
6. Commissioning, operation
Mechanical connection
The transmitter is designed for mounting on at mounting plates. For screwing it to
the mounting plate, the instrument has a mounting bore
Ø 5.5 mm and an elongated hole with a width of 5.5 mm.
The IP 55 ingress protection (front panel) is only guaranteed when the supplied
cable gland, with internal sealing element, and corrugated hose are used. To
ensure this, the M8 connection cable is pre-assembled with the associated corrugated hose / cable gland combination, and then mounted into the built-in M8

connector on the instrument.
By applying slight pressure the cable snaps into the connector. Screw the cable
gland to the case. Then the internal sealing of the cable gland is press-tted to the
cable.
GB
When mounting the instrument, ensure that the air lter will not become clogged
by dust or liquid.
Opening the case is not allowed, as this will lead to permanent instrument
damage.
Process connection
When connecting the instrument, the lines must be free of pressure.
The instrument must be protected from pressure spikes by taking appropriate
measures
Only for operation with suitable media
Observe maximum pressure
Observe the permissible overpressure
The pressure connections are marked with ⊕ and ⊖ symbols on the instrument.
For dierential pressure measurements, the higher pressure should be connected
to the ⊕ side and the lower pressure to the ⊖ side of the instrument.
Electrical connection
The electrical connection of the instrument must be carried out in accordance
with both the applicable codes and standards (VDE regulations) and the local
power supply company's regulations
Before connecting the instrument the plant must be electrically isolated
Safety fuses should be series-connected and sized appropriately for the power
rating
The instrument has a
3-wire connection and its
electrical connection is

Commissioning
Before commissioning, the instrument and all electrical wiring must be properly
installed. All connection lines must be run so that no mechanical forces will act
on the instrument.
The pressure measuring lines should be constructed so that a sucient gradient
exists, so that, for example, no air pockets can occur when measuring liquids
nor water pockets when measuring gases. If the gradient required cannot be
achieved, water or air separators must be tted at the appropriate points.

6. Commissioning, operation ... 8. Dismounting, return ...
The pressure measuring lines must be as short as possible and should be
arranged without sharp radii in order to avoid any disruptive time lags.
Before commissioning the instrument, check the mechanical connections to
ensure they are leak-tight.
7. Maintenance
The instruments are maintenance-free.
In order to ensure safe and reliable operation and a long service life for the
instrument, we recommend carrying out the following tests at regular intervals:
- Measurement signal test
- Leak-tightness checks at the pressure connection lines
- Electrical connection checks (clamp connection of the cables)
The testing intervals are to be adapted to the specic operating and ambient
conditions. In applications where various instrument components interact,
the operating instructions of all the other instruments involved must also be
observed.
Repairs are only to be carried out by the manufacturer or appropriately trained
skilled personnel.
8. Dismounting, return and disposal
GB
WARNING!
Residual media in dismounted instruments 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 Return
All defective or faulty instruments must be sent directly to our repair department.
9.3 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.
