1.5 Intended use
- The hydrostatic probes LMK 457 and LMK 458 have
been designed especially for shipbuilding and offshore
applications with rough environmental and operation
conditions. The probes are suitable for level measure-
ment of fluids or pasty media (no solids and frozen me-
dia) in open tanks, containers, or reservoirs. As medium
all fluids can be used which are compatible with the ma-
terials of housing, sealing and cable. Based on a rugged
and reliable capacitive ceramic sensor the probe is
qualified for measuring small filling heights with high ac-
curacy. Typical areas of use are ballast tanks, fuel and
oil tanks as well as ser-vice and waste water tanks. The
probes as standard complies with the requirements of
Germanischer Lloyd (GL) and Det Norske Veritas
(DNV). The certificates are available for download on
our homepage: http:// www.bdsensors.com/products

Fig. 1 manufacturing label
!The manufacturing label must not be removed from the
device!
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 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 possibly protective cap directly before starting
assembly. The possibly delivered protective cap has to
be stored! Place this 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!
!When placing the probe into operation or after mainte-
nance work, the probe has to be submerged slowly into
the medium! A rough immersion into the medium can
damage or destroy the diaphragm.
!For installations outdoor and in damp areas following
these instructions:
- Choose an assembly position, which allows the
flow-off of splashed water and condensation.
- 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 so-
lar irradiation, measurement errors may be caused.
Take note for screw-in and flange transmitter that no
inadmissibly high mechanical stresses occur at the
pressure port as a result of the installation, since this
may cause a shifting of the characteristic curve or to the
demage.
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 installing the device outdoor and there is any danger
of lightning or overpressure we suggest putting a
overpressure protection unit between the supply/switch
cabinet and the device to prevent damage.
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 probe
- Install the device according to your demands.
Usually, the probe is delivered without mounting acces-
sories. But BD SENSORS offers different accessories
on request e.g. mounting clamp, terminal clamp or
mounting flange.
Do not use freely suspended probes with an FEP cable
if effects due to highly charging processes are ex-
pected.
3.4 Installation steps for flange transmitter
- Please ensure that the mounting thread is clean and
free of damage.
- Check to ensure that the O-ring fits properly in the
groove.
- Screw in the mounting thread of the transmitter in the
transmitter flange, by hand.
- Next, tighten it by an open-end wrench. (approx. 25 Nm)
- Install the flange according to your demands.
If a new transmitter flange is needed, it can be ordered
from BD SENSORS.
3.5 Installation steps for screw-in transmitter
- Please ensure that the mounting thread is clean and
free of damage.
- Check to ensure that the O-ring fits properly in the
groove.
- Ensure that the sealing surface of the taking part e.g.
welding socket is perfectly smooth and clean.
- Screw the device in the corresponding thread by hand.
- Next, tighten it by an open-end wrench. (approx. 25 Nm)
3.6 Removing the protection cap (for probe)
For the protection of the diaphragm, some of the probes
have a plugged-on protection cap. If the device shall be used
in high-viscosity media such as sludge, a removal of the cap
before start-up is necessary. Thus, the sensor becomes
flush and the medium will attain quickly to the diaphragm.
If it is necessary for your application to remove the
protection cap, this has to be done with utmost care. To
prevent a damage of the diaphragm, please follow the
instructions below.
Removal by hand
- Hold the probe in a way that the protection cap points
upwards.
- Hold the probe with one hand on the sensor section (1).
- Remove the protection cap (2) with the other hand.

will not be damaged!
4. Electrical Installation
WARNING! Install the device only when depressurized
and currentless!
Establish the electrical connection of the device according to
the technical data shown on the manufacturing label, the
following table and the wiring diagram.
Pin configuration:
Wiring diagram:
!A minimum static bending radius has to be complied
with. For static installation use the 10-fold cable diame-
ter, for dynamic applications use the 20-fold diameter.
!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 has to be used; if a cable extension is
necessary, also a shielded cable has to be used.
If a transition is desired from a probe cable with gauge
tube to a cable without gauge tube, then we recom-
mend our terminal box KL 1 or KL 2.
Devices with TPE-cable
- Application in water with a temperature >70°C de-
stroys the cable
- Applications at media temperatures >70°C have to be
clarified with BD|SENSORS in advance
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

6. Placing out of service
WARNING! When dismantling the device, it must
always be done in the depressurized and currentless
condition! Check also if the medium has to be drained
off 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 when switched of
using a damp cloth and non-aggressive cleaning solutions.
With certain media, however, the diaphragm may be polluted
or coated with deposit. It is recommended to define corre-
sponding service intervals for control. 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 read therefore the chapter “Ser-
vice/Repair” below.
!An incorrect cleaning can cause irreparable damages
on diaphragm. Never use spiky objects or pressured air
for cleaning the diaphragm.
8. Service / Repair
8.1 Recalibration
During the life-time of a probe, 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
Before every return of your device, whether for recalibration,
decalcification, modifications or repair, it has to be cleaned
carefully and packed shatter-proofed. You have to enclose a
notice of return with detailed defect description when
sending the device. If your device came in contact with
harmful substances, a declaration of decontamination is
additionally required. Appropriate forms can be downloaded
from our homepage www.bdsensors.com. Should you
dispatch a device without a declaration of decontamination
and if there are any doubts in our service department
regarding the used medium, repair will not be started until an
acceptable declaration is sent.
If the device came in contact with hazardous
substances, certain precautions have to be
complied with for purification!
