2. Safety
WARNING!
Before installation, commissioning and operation, ensure that
the appropriate dierential pressure transmitter has been
selected in terms of design and specic measuring conditions.
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.
Only work on the gauge with the voltage disconnected.
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
The dierential pressure transmitters of the DELTA-line product family are
primarily used for the monitoring of low dierential pressures where there are high
requirements in terms of one-sided overpressure and static pressure.
Typical markets for these products are the shipbuilding industry, process heating
technology, the heating, ventilation and air-conditioning industries, the water/
wastewater industry, and machine building and plant construction. For these,
the main function of the measuring instruments is the monitoring of lters,
compressors and pumps.
GB
The instrument 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.

As a power supply, an unstabilised DC power supply is sucient in the range of
the specied limits. It is important to ensure that the applied power supply is at
least greater than the maximum required voltage drop from the external display
and evaluation units; i.e. the voltage at the pressure transmitter must not fall
below 10 V.

an elastic diaphragm (1).

The deection, which is proportional to the dierential pressure, is transmitted to
the movement (4) in the indicating case via a pressure-tight and low friction rocker
arm (3).
A magnet (5), xed to the rear of the movement, aects the electromagnetic eld
of the HALL sensor. The signal that results from this is converted to a standardised
current output signal by the signal conditioning board (6).
Overpressure safety is provided by metal bolsters (7) resting against the elastic

5. Transport, packaging and storage
5.1 Transport
GB
Check the 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).
5.3 Storage
Permissible conditions at the place of storage
Storage temperature: -40 ... +70 °C
In order to prevent damage, the following points should be noted for the
storage of the pressure transmitters:
■
Leave the measuring instruments in their original packaging
■
Following any possible removal of the measuring instruments, e.g. for testing,
the instrument should again be stored in its original packaging
Avoid exposure to the following factors:
■
Direct sunlight or proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust, humidity and corrosive gases
■
Potentially explosive environments, ammable atmosphere
WARNING!
Before storing the instrument, any residual media must be
removed. This is of particular importance if the medium
is hazardous to health, e.g. caustic, toxic, carcinogenic,
radioactive, etc.

6.1 Mechanical connection
■
In accordance with the general technical regulations for pressure gauges (e.g.
EN 837-2 “Selection and installation recommendations for pressure gauges”).
■
Mounting of the pressure connections according to axed symbols, ⊕ high
pressure, ⊖ low pressure
■
Mounting by means of:
- rigid measuring line or
- wall mounting with available mounting links
■
Process connections 2 x G 1/4 female, lower mount (LM), in-line, centre
distance 26 mm, operating position NL 90 (nominal position) per DIN 16257
(i.e. vertical dial), design the threads of the pressure connection in accordance
with EN 837-3 (section 7.3.2).
■
Prior to the installation of the pressure gauge, clean the measuring lines
thoroughly by tapping and blowing or rinsing
■
Protect measuring instruments from contamination and high temperature
changes!
■
The pressure gauge must be mounted free from vibration and should be
aligned so that it is easy to read. It is recommended that an isolation device is
interposed between the pressure tapping point and the pressure gauge, which
will enable the replacement of the pressure gauge and a zero point check while
the plant is running. The instruments should be protected against coarse dirt
and wide uctuations in ambient temperature.
GB
■
Correct sealing of the connections must be made using suitable at gaskets,
sealing rings or WIKA prole sealings. In order to orientate the gauge so that
the on-site display can be read as well as possible, a clamp socket or union nut
should be used. When screwing on and unscrewing the pressure gauges they
should not be gripped by the case, but rather only on the spanner ats of the
connection!

Measuring assemblies
The preferred measuring assemblies for various possible applications are
specied in DIN 19216.
The following schematic diagram shows a recommended assembly for liquid
media. As throttling devices, dierential pressure transducers should be provided
in accordance with DIN 1952 (issue 07.82), now replaced by EN 5167/1.
The dierential pressure lines must be made from metal, their bore must not
be less than 4 mm and the eective length between the valve manifold and the
dierential pressure transmitter must be at least 500 mm.
GB
In addition, the length and the bore of
the pressure lines should be such that,
with cold lines, the response time of
the pressure gauge is not more than
5 seconds.

Safety instructions for installation
■
Follow the installation and safety instructions within the
operating instructions.
■
Install instruments in accordance with the manufacturer's
instructions and the valid standards and regulations.
■
The instruments do not provide for incorporated overcurrent protectors!
Once the pressure connection and the electrical connections have been made,
the pressure transmitters are ready for immediate use.
Commissioning
During the commissioning process pressure surges must be avoided at all costs.
Open the shut-o valves slowly.

6.2 Electrical zero point (4 mA)
The zero point adjustment is made by an adjustment screw in the front, which,
depending on the instrument model, is accessible by loosening the window or the
GB
locking screw. By turning the adjustment screw using a screwdriver the desired zero
point is set.
If the mechanical zero point has been altered via the
adjustment screw, the electrical zero point must be
matched again to the mechanical one.
For this, the dierential pressure transmitter must rst be
depressurised.
Remove the entire cable cover on the right-hand side
of the transmitter. To do this, undo the screw on the
top of the cable cover cap completely with a slotted
screwdriver (0.6 x 3.5 mm). Remove the screw. Pull the
cable cover , along with the socket insert , out from the
cable socket baseplate .
This isolates the transmitter from the voltage supply.
Take the cable cover cap from the cable cap and
push the socket insert out, downwards, completely
through the cable cap .
Bridge contacts 5 and 6 on the socket insert with a
short length of wire, stripped at both ends (maximum
permissible resistance 30 Ω).
Reassemble the connector in the reverse order. Insert the
connector, with the piece of wire mounted, into the pin
insert . This remakes the voltage supply.
Within a max. of 30 seconds, the new zero point will be
saved within the electronics. During this time, the current in
the loop will rise to 9.5 mA.
The new zero point is maintained, even with a loss of
power, for an extended period.
Once more, disconnect the connector in the order
described above and remove the piece of wire. After again
assembling the connector, the electrical output signal will
once more match the display of the mechanical pointer.
In order that the ingress
protection is maintained, the
seals must be retted.

6.3 Setting up a voltage supply
The voltage supply is made via a power supply unit or a control unit which
provides the energy limitation.
The power supply for the pressure transmitter must be made via an energy-
limited electrical circuit in accordance with section 9.3 of UL/EN/IEC 61010-1, or
an LPS to UL/EN/IEC 60950-1, or class 2 in accordance with UL1310/UL1585
