3.2Principle of operation
SITRANS LVL200Sis a point level sensor with tuning fork for
level detection.
It is designed for industrial use in all areas of process
technology and can be used in liquids.
Typical applications are overfill and dry run protection.With a
tuning fork of only 40 mm length,SITRANS LVL200Scan be
also mounted,e.g.in pipelines from DN 25.The small tuning
fork allows use in vessels,tanks and pipes.Thanks to its
simple and robust measuring system,SITRANS LVL200Sis
virtually unaffected by the chemical and physical properties of
the liquid.
It functions even under difficult conditions such as turbulence,
air bubbles,foam generation,buildup,strong external vibration
or changing products.
Fault monitoring
The electronics module of SITRANS LVL200Scontinuously
monitors via frequency evaluation the following criteria:
lStrong corrosion or damage on the tuning fork
lloss of vibration
lLine break to the piezo drive
If a malfunction is detected or in case of power failure,the
electronics takes on a defined switching condition,i.e.the
relay deenergises (safe condition).
The tuning fork is piezoelectrically energised and vibrates at its
mechanical resonance frequency of approx.1200 Hz.The
piezos are fixed mechanically and are hence not subject to
temperature shock limitations.The frequency changes when
the tuning fork is covered by the medium.This change is
detected by the integrated oscillator and converted into a
switching command.
SITRANS LVL200Sis a compact instrument,i.e.it can be
operated without external evaluation system.The integrated
electronics evaluates the level signal and outputs a switching
signal.With this switching signal,a connected device can be
operated directly (e.g.a warning system,aPLC,a pump etc.).
Data for power supply are specified in chapter "Technical
data".

3.3Operation
With the factory setting,products with a density >0.07 g/cm³
(0.025 lbs/in³)can be measured.The instrument can be
adapted if products with lower density should be measured.
On the electronics module you will find the following indicating
and adjustment elements:
lSignal lamp for indication of the switching condition (green/
red)
lDIL switch for sensitivity adjustment
lMode adjustment for selection of the switching condition
(A/B)
3.4Storage and transport
Your instrument was protected by packaging during transport.
Its capacity to handle normal loads during transport is assured
by a test according to DIN EN 24180.
The packaging of standard instruments consists of environ-
ment-friendly,recyclable cardboard.In addition,the sensor is
provided with a protective cover of ABS.For special versions
PE foam or PE foil is also used.Dispose of the packaging
material via specialised recycling companies.
Transport must be carried out under consideration of the notes
on the transport packaging.Nonobservance of these instruc-
tions can cause damage to the device.
The delivery must be checked for completeness and possible
transit damage immediately at receipt.Ascertained transit
damage or concealed defects must be appropriately dealt
with.
Up to the time of installation,the packages must be left closed
and stored according to the orientation and storage markings
on the outside.
Unless otherwise indicated,the packages must be stored only
under the following conditions:
lNot in the open
lDry and dust free
lNot exposed to corrosive media
lProtected against solar radiation
lAvoiding mechanical shock and vibration
