3.2 Principle of operation
SITRANS LVL200E is a point level sensor with tuning fork for point
level detection.
It is designed for industrial use in all areas of process technology and
can be used in liquids.
Typicalapplicationsareoverllanddryrunprotection.Thesmall
tuning fork allows use in all kinds of tanks and vessels. Thanks to its
simple and rugged measuring system, SITRANS LVL200E is virtually
unaectedbythechemicalandphysicalpropertiesoftheliquid.
Itfunctionsevenunderdicultconditionssuchasturbulence,airbub-
bles, foam generation, buildup, strong external vibration or changing
products.
Function monitoring
The electronics module of SITRANS LVL200E continuously monitors
the following criteria via frequency evaluation:
• Strong corrosion or damage on the tuning fork
• Loss of vibration
• Linebreaktothepiezodrive
If one of these faults is detected, the electronics signals it via a
denedcurrenttothesignalconditioninginstrument.Theconnection
cable to the sensor is also monitored for line break and short-circuit.
Thetuningforkispiezoelectricallyenergisedandvibratesatits

xedmechanicallyandarehencenotsubjecttotemperatureshock
limitations.The frequency changes when the tuning fork is covered
by the medium.This change is detected by the integrated electronics
module, transferred as a current value to the processing system and
converted there into a switching command.

4.1 General instructions
Make sure that all parts of the instrument coming in direct contact
with the process, especially the sensor element, process seal and
processtting,aresuitablefortheexistingprocessconditions,such
as process pressure, process temperature as well as the chemical
properties of the medium.
Youcanndthespecicationsinchapter"Technical data" and on the
nameplate.
The instrument is suitable for standard and extended ambient condi-
tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1.
In general, SITRANS LVL200E can be installed in any position.The
instrument only has to be mounted in such a way that the tuning fork
is at the height of the desired switching point.
The tuning fork has lateral markings (notches) that indicate the
switching point with vertical mounting. The switching point applies
to water in conjunction with the basic setting of the density switch
≥0.7g/cm³(0.025lbs/in³).WhenmountingSITRANSLVL200E,
make sure that this marking is at the height of the requested switch-
ing point. Keep in mind that the switching point of the instrument will

The vibrating level switch is a measuring instrument and must be
treated accordingly. Bending the vibrating element will destroy the
instrument.
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
Use the hexagon above the thread for screwing in.
Metric threads
In the case of instrument housings with metric thread, the cable
glands are screwed in at the factory.They are sealed with plastic
plugs as transport protection.
You have to remove these plugs before electrical connection.
NPT thread
In the case of instrument housings with self-sealing NPT threads, it is
not possible to have the cable entries screwed in at the factory.The
free openings for the cable glands are therefore covered with red dust
protection caps as transport protection.
Prior to setup you have to replace these protective caps with ap-
proved cable glands or close the openings with suitable blind plugs.
4.2 Mounting instructions
SITRANSLVL200Ehasadenedthreadstartingpoint.Thismeans
that every SITRANS LVL200E is in the same fork position after being
screwed in. Remove therefore the supplied seal from the thread of
SITRANS LVL200E. This seal is not required when using a welded
socket with O-ring in front.
Keep in mind that this welded socket is not suitable for coated instru-
ment versions.
Screw SITRANS LVL200E completely into the welded socket. The
later position can be determined already before welding. Mark the
appropriate position of the welded socket. Before welding, unscrew
SITRANS LVL200E and remove the rubber ring from the welded
socket. The welded socket has a marking (notch). Weld the socket
with the notch facing upward, or in case of pipelines (DN 32 up to
DN50),alignedwiththedirectionofow.

Duetotheeectsofagitators,equipmentvibrationorsimilar,the
level switch can be subjected to strong lateral forces. For this reason,
do not use an overly long extension tube for SITRANS LVL200E,
but check if you can mount a level switch on the side of the vessel in
horizontalposition.
Extreme vibration caused by the process or the equipment, e.g.
agitators or turbulence in the vessel, can cause the extension tube of
SITRANS LVL200E to vibrate in resonance.This leads to increased
stress on the upper weld joint. Should a longer tube version be neces-
sary, you can provide a suitable support directly above the tuning fork
to secure the extension tube.
This measure applies mainly to applications in Ex areas category 1G
or WHG. Make sure that the tube is not subject to bending stress due
to this measure.
Fig. 9: Lateral suppot of SITRANS LVL200E
Instruments with enamel coating should be treated very carefully and
shocks should be avoided. Unpack SITRANS LVL200E directly before
installation. Insert SITRANS LVL200E carefully into the vessel open-
ing and avoid touching any sharp vessel parts.
The second seal of the gas-tight leadthrough (option) prevents an
uncontrolled leakage of the medium.The service life of the gas-tight
leadthrough depends on the chemical resistance of the materials.
See "Technical data".
Caution:
If it is determined (e.g. via an error message from SITRANS LVL200E)
that medium has already penetrated into the vibrating element, the
instrument must be exchanged immediately.
