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, inappropri-
ate use, modification or damage, no liability is assumed
and warranty claims will be excluded.
1.5 Intended use
- The pressure transmitter DMP 303 / DMP 304 has been
especially designed for the overpressure measuring.
- 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. In addition it has
to be ensured, that this medium is compatible with the
media wetted parts. For questions please contact our
sales team!

3.1 Mounting and safety instructions
WARNING! Install the device only when depressurized
and currentless!
WARNING! This device may only be installed by quali-
fied technical personnel who has read and understood
the operating manual!
!
Handle
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 pre-
vent damage of the device and the plant!
!
For installations outdoor and in damp areas following
these instructions:
- 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 cable gland or outlet device, 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. By this the
operability of the device can be affected or dam-
aged. If the internal pressure increases due to solar
irradiation, measurement errors may be caused.
Take note that no assembly stress occurs at the
pressure port, since this may cause a shifting of the
characteristic curve. This is especially important for very
small pressure ranges as well as for devices with a
pressure port made of plastic.
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 General installation steps
- Carefully remove the pressure measuring device from
the package and dispose of the package properly.
- Go ahead as detailed in the specific instructions below.
3.3 Installation steps for EN 837
- Use a suitable seal, corresponding to the medium and
the pressure input (e. g. a cooper gasket).
- Ensure that the sealing surface of the taking part is per-
fectly smooth and clean.
- Screw the device into the corresponding thread by hand.
- Tighten it with a wrench (for G1/4": approx. 20 Nm; for
G1/2": approx. 50 Nm).
3.4 Installation steps for internal threads M20x1.5 and
9/16" UNF
- Screw the high pressure connection into the internal
thread of the DMP 334 according to the description of
the manufacturer and tighten it properly.
DANGER! The high pressure tube seals metal-to-
metal in the chamfer of the pressure port. No fur-
ther seal is allowed with this high pressure connec-
tion. A wrong installation can cause enormous dan-
ger!
4. Electrical Installation
WARNING! Install the device in currentless condition
only!
Establish the electrical connection of the device according to
the technical data shown on the manufacturing label, the
following table and the respective wiring diagram.
