OPTISWITCH 5200 C, 5250 C - with two-wire output 7
OPTISWITCH 5200 C, 5250 C is a level sensor with tuning
fork for level detection.
Product description
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, OPTISWITCH 5200 C, 5250
C can 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, OPTISWITCH 5200 C, 5250 C is 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 OPTISWITCH 5200 C, 5250 C
continuously monitors via frequency evaluation the following
criteria:
l Strong corrosion or damage on the tuning fork
l loss of vibration
l Line break to the piezo drive
If one of these faults is detected, the electronics signals it via a
defined current to the signal conditioning instrument. The
connection cable to the sensor is also monitored on line break
and short-circuit.
Physical principle
The tuning fork is piezoelectrically energised and vibrates at its
mechanical resonance frequency of approx. 1200 Hz. The
piezos are fastened mechanically and are hence not subject to
temperature shock limitations. When the tuning fork is
submerged in the product, the frequency changes. This
change is detected by the integrated oscillator, transferred to
the signal conditioning instrument as current value and
converted into a switching command.
Power supply
Depending on your requirements, OPTISWITCH 5200 C, 5250
C with two-wire electronics can be connected to different
signal conditioning instruments. Compatible signal conditioning instruments are listed under "Technical data".
The exact range of the power supply is stated in the "Technical
data" in the "Supplement".

Product description
3.3 Operation
The switching condition of OPTISWITCH 5200 C, 5250 C with
plastic housing can be checked when the housing is closed
(signal lamp). With the basic setting, products with a density
>0.7 g/cm³ (>0.025 lbs/in³) can be detected. 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:
l signal lamp for indication of the switching condition (green/
red)
l DIL switch for adaptation to the product density
3.4 Storage and transport
Packaging
Storage and transport tem-
perature
Your instrument was protected by packaging during transport.
Its capacity to handle normal loads during transport is assured
by a test according to DIN 55439.
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.
l Storage and transport temperature see "Supplement -
Technical data - Ambient conditions"
l Relative humidity 20 … 85 %

4.1 General instructions
Switching point
In general, OPTISWITCH 5200 C, 5250 C can be mounted in
any position. The instrument must be mounted in such a way
that the tuning fork is at the height of the requested switching
point.
The tuning fork has lateral markings (notches), marking the
switching point with vertical mounting. The switching point
refers to water with the basic setting of the sensitivity switch
>=0.7 g/cm³ (>=0.025 lbs/in³). When mounting OPTISWITCH
5200 C, 5250 C, make sure that this marking is at the height of
the requested switching point. Keep in mind that the switching
point of the instrument is shifted if the medium has a density
other than water - water =1 g/cm³ (=0.036 lbs/in³). For
products <0.7 g/cm³ (<0.025 lbs/in³)
and >0.5 g/cm³
(>0.018 lbs/in³) the density switch must be set to >=0.5 g/cm³.
