WARNING! To avoid operator hazards and damages of
the device, the following instructions have to be worked
out by qualified technical personnel.
1.4 Limitation of liability
By non-observance of the operating manual, inappropriate

warranty claims will be excluded.
1.5 Intended use
- Pressure transmitters DMK 456, DMK 457, DMK 458
and DMP 457 have been designed for typical applica-
tions in shipbuilding and offshore constructions. They
are suitable for measuring tasks with fluids and gases.
Typical applications of DMK 456 and DMK 458 are
pressure monitoring for loading and discharge process-
es as well as level measurement for ballast and product
storage tanks. Preferred areas of usage for DMK 457
are gears, compressors, boilers, pneumatic controls, el-
evators, oxygen applications and e.g. level measure-
ment into ballast tanks, etc. With mechanical versions
G1/2" open port or G1/2" flush DIN 3852 the DMK 457
is especially suited for viscous, pasty or contaminated
media due to the easily reachable ceramic diaphragm.
Preferred areas of usage for DMP 457 are diesel en-
gines, gears, compressors, pumps, boilers, hydraulic
and pneumatic controls as well as elevators. The pres-
sure transmitters DMK 456, DMK 457, DMK 458 and
DMP 457 are certificated by Det Norske Veritas ▪ Ger-
manischer Lloyd (DNV▪GL) as standard. The certificates
are available for download on our homepage: http://
www.bdsensors.com/products/down-load/ certificates
- It is the operator's responsibility to check and verify the
suitability of the device for the intended application. If
any doubts remain, please contact our sales department
in order to ensure proper usage. BD SENSORS is not
liable for any incorrect selections and their effects!
- Permissible media are gases or liquids, which are com-
patible with the media wetted parts described in the data
sheet. In addition it has to be ensured, that this medium
is compatible with the media wetted parts.

WARNING! Danger through improper usage!
1.6 Package contents
Please verify that all listed parts are undamaged included in
the delivery and check for consistency specified in your
order:

2. Product identification
The device can be identified by its manufacturing label. It
provides the most important data. By the ordering code the
product can be clearly identified.

3. Mechanical installation
3.1 Mounting and safety instructions
WARNING! Install the device only when depressurized
and currentless!
WARNING! This device may only be installed by
qualified technical personnel who has read and under-
stood the operating manual!
!
Handle this high-sensitive
measuring device with care, both in packed and
unpacked condition!
!
There are no modifications/changes to be made on the
device.
!
Do not throw the package/device!
!
To avoid damaging the diaphragm, remove packaging
and protective cap directly before starting assembly.
The delivered protective cap has to be stored!
!
Place the protective cap on the pressure port again
immediately after disassembling.
!
Handle the unprotected diaphragm very carefully - it is
very sensitive and may be easily damaged.
!
Do not use any force when installing the device to
prevent damage of the device and the plant!
!
For installations outdoor or in moist surroundings, the
following points have to be observed:
-
-
-
-
!
For devices with gauge reference in the housing (small
hole next to the electrical connection), install the device
in such a way, that the gauge reference is protected
from dirt and moisture. Should the device be exposed to
fluid admission, the functionality will be blocked by the
gauge reference. An exact measurement in this condi-
tion is not possible. Furthermore this can lead to dam-
ages on the device.
Take note that no inadmissibly high mechanical stress
occurs at the pressure port, since this may cause a
shifting of the characteristic curve or to the demage.
This is especially important for very small pressure
ranges.
In hydraulic systems, position the device in such a way
that the pressure port points upward (ventilation).
Provide a cooling line when using the device in steam
piping.
If there is any danger of damage by lightning or
overpressure when the device is installed outdoor, we
suggest putting a sufficiently dimensioned overpressure
protection between the supply or switch cabinet and the
device.
3.2 Mounting and safety instructions oxygen
DANGER! Explosion hazard, with devices for oxygen
applications, when used improperly. To ensure a usage
without danger, the following points must be adhered to:

3.3 General installation steps
- Carefully remove the pressure measuring device from
the package and dispose of the package properly.
electronic precision
- Go ahead as detailed in the specific instructions below.
To prevent moisture admission in the plug the de-
vice should be installed electrically after mounting,
at once. Otherwise a moisture admission has to be
blocked e.g. by using a suitable protection cap.
(The ingress protection in the data sheet is valid
for the connected device.)
Choose an assembly position, which allows the
flow-off of splashed water and condensation. Avoid
permanent fluid at sealing surfaces!
When using a device with cable gland or cable out-
let, turn the outgoing cable downwards. If the cable
has to be turned upwards, then point it downward
so the moisture can drain.
Install the device in such a way that it is protected
from direct solar irradiation. Direct solar irradiation
can lead to the permissible operating temperature
being overstepped in the worst case. Through this,
the operability of the device can be affected or
damaged. If the internal pressure increases due to
solar irradiation, temporary measurement errors
may occur.
Make sure, your device has been ordered and de-
livered as a special version for oxygen applica-
tions. You can check the manufacturing label (see
figure 1). If the ordering code ends with "007", then
the device is suitable for oxygen applications.
At time of delivery the device is packed into a plas-
tic bag in order to prevent it from impurity. Please
observe the indication label "Device for oxygen,
unpack only directly before assembling". Also,
avoid any skin contacts during unpacking and as-
sembly, in order to prevent greasy residues on the
device.
During installation, the respective explosion protec-
tion regulations have to be met. Check, if ATEX-
approval is necessary for this type (oxygen) de-
vice. (the delivered device has no ATEX-approval)
Note the entire design requirements meet the
standard demand of BAM (DIN 19247).
Transmitters with o-rings of FKM
permissible maximum values: 25 bar/ 150° C (with
BAM-approval).
