WARNING -
In order to avoid hazards to operators and
damages to the device, the following instructions have to be
performed by qualified technical personnel.
WARNING -
Adhere to the safety and operating instructions
stated in the operation manual. Effective regulations on
occupational safety, accident prevention as well as national
installation standards and approved engineering techniques
must in addition be complied with.
Limitation of liability
If the instructions in the mounting instructions / operating
manual are not adhered to or if the device is inappropriately
used, modified or damaged, liability is not assumed and
warranty claims will be excluded.
Intended use
Ensure that the medium is compatible with the media-wetted
parts and that the device is suitable for the application without
restrictions. The technical data listed in the current data sheet is
binding.

Mounting
Fasten the probe properly according to your requirements.
Always immerse the device slowly into the fluid to be measured!
If the probe strikes the liquid surface, the diaphragm could be
damaged or destroyed.
For
LMK 382 / LMK 382H in flange version ensure that the
mounting thread is clean and undamaged and that the O-
ring is undamaged and seated in the designated groove at
the probe end. After screwing in by hand, the probe has to
be
tighten using an open-end wrench (approx. 25 Nm).

NOTE -
In the case of relative pressure gauges, the cable
contains a ventilation hose for pressure equalization. Route the
end of the cable into an area or suitable connection box which is
as dry as possible and free from aggressive gases, in order to
prevent any damage.
NOTE -
Use a shielded and twisted multicore cable for the
electrical connection.
NOTE -
Devices with TPE-cable: application in water with a
temperature > 70°C destroys the cable; applications at media
temperatures > 70°C have to be clarified with BD|SENSORS in
advance.

Removal of protective cap (if necessary)
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.
Removal by hand
1.
Hold the probe in a way that the protection cap points
upwards.
2.
Hold the probe with one hand on the sensor section (1).
3.
Remove the protection cap (2) with the other hand.
Removal with a tool (recommended)
1.
Hold the probe in a way that the protection cap points
upwards.
2.
Slide a small tool such as a screwdriver (8) straight through
two opposite drill holes in the protective cap (2).
3.
Lever it off by moving up the handle of the screwdriver.
NOTE -
Make sure that the sensor (7) under the protection
cap will not be damaged!
Separability
(with LMK 358, LMK 358H, LMK 808, LMK 858,
LMP 308, LMP 308i and LMP 808)
In order to facilitate stock keeping and maintenance, the probe
head is plugged to the cable assembly with a connector and can
be easily changed.
Disassembly
1.
Hold the probe on the sensor
section (2) with one hand and
turn the nut (4) carefully to the
left with the other hand. Prevent
torsion of the cable section (3)
against the housing!
2.
While screwing and pulling off
the sensor section (2) from the
cable section (3), hold it straight
to prevent damages on the
plugs.
Assembly
O-rings are not damaged (5, 6) or damaged O-rings
have been replaced.
Radial O-rings (5) have been greased with Vaseline or
O-ring grease.
Any grease residues have been removed from the axial
O-ring (6).
1.
Plug the cable section (3) straight into the plug of the
sensor section (2).
2.
Hold the probe onto the sensor section (2) with one
hand. Screw on and tighten the nut (4) carefully with the
other hand. Prevent torsion of the cable section (3)
against the housing!
