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 understood
the operating manual!
!
Handle this high-sensitive electronic precision
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 i nstalling the device to prevent 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 device 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 damaged. 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 perfectly 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-tometal in the chamfer of the pressure port. No further seal is allowed with this high pressure connection. A wrong installation can cause enormous danger!
4. Electrical Installation
WARNING! Install the device in currentless condition
only!

80% Signal
3-wire-system (current / voltage)
Generation of the 80 % calibration signal:
For the generation of the 80 % calibration signal you have to
put on the connection contacts 80+ and 80- a voltage about
minimal 5 V in the pressureless condition. The maximum
voltage has to be the same as the maximum supply voltage
of the device. By feeding the voltage on 80+ and 80- an
additional current about 12.8 mA is given out and there flows
a complete current about 16.8 mA. Please note for IS-devices
that the activation of the calibration signal has to run about
the same supply as the supply of the signal circuit.
!
For devices with cable socket, you have to make sure
that the external diameter of the used cable is within the
allowed clamping range. Moreover you have to ensure
that it lies in the cable gland firmly and cleftlessly!
!
Please note for devices with ISO 4400 plug, that the
cable socket has to be mounted properly to ensure the
ingress protection mentioned in the data sheet. Please
check if the delivered seal is placed between plug and
cable socket. After connecting the cable fasten the cable
socket on the device by using the screw.
!
On devices with field housings, the terminal clamps are
situated under the metal cap. To install the device
electrically, the cap must be screwed off. Before the
cover is screwed on again, the O-ring and the sealing
surface on the housing have to be checked for damages
and if necessary to be changed! Afterwards screw the
metal cap on by hand and make sure that the field
housing is firmly locked again.
!
Prevent the damage or removal of the PTFE filter which
is fixed over the end of the air tube on devices with cable
outlet and integrated air tube.
For the electrical connection a shielded and twisted
multicore cable is recommended.
If a transition is desired from a transmitter cable with
gauge tube to a cable without gauge tube, we
recommend our terminal box KL 1 or KL 2.
5. Initial start-up
WARNING! Before start-up, the user has to check for
proper installation and for any visible defects.
WARNING! The device can be started and operated by
authorized personnel only, who have read and understood the operating manual!
WARNING! The device has to be used within the
technical specifications, only! (compare the data in the
data sheet)
6. Placing out of service
WARNING! Disassemble the device only in current and
pressure less condition! Check before disassembly, if it
is necessary to drained off the media before dismantling!
WARNING! Depending on the medium, it may cause
danger for the user. Comply therefore with adequate
precautions for purification.
7. Maintenance
In principle, this device is maintenance-free. If desired, the
housing of the device can be cleaned using a damp cloth and
non-aggressive cleaning solutions, in switched-off state.
Depending on the measuring medium, however, the diaphragm may be polluted or coated with deposit. Is there a
pollution tendency of the medium, the user has to determine
the appropriate cleaning interval. After placing the device out
of service correctly, the diaphragm can usually be cleaned
carefully with a non-aggressive cleaning solution and a soft
brush or sponge. If the diaphragm is calcified, it is recommended to send the device to BD SENSORS for decalcification. Please note the chapter “Service/Repair” below.
!
A false cleaning of the device can cause an irreparable
damage on the diaphragm. Therefore never use pointed
objects or pressured air for cleaning the diaphragm.
8. Service / Repair
8.1 Recalibration
During the life-time of a transmitter, the value of offset and
span may shift. As a consequence, a deviating signal value in
reference to the nominal pressure range starting point or end
point may be transmitted. If one of these two phenomena
occurs after prolonged use, a recalibration is recommended
to ensure furthermore high accuracy.
8.2 Return
Upon every return of the device, no matter if for recalibration,
decalcification, modifications or repair, it is necessary
to contact us to guarantee a quick execution of your
request. Please inform us by sending an email to:
return@bdsensors.de. Include the number of devices sent
