30427-EN-060831
OPTISWITCH 5100 C, 5150 C - with transistor output 7
OPTISWITCH 5100 C, 5150 C is a 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, OPTISWITCH 5100 C, 5150
C can be also mounted, e.g. in pipelines from DN 25. The
small tuning fork allows use in vessels, tanks and pipes.
Page 8
Product description
Thanks to its simple and robust measuring system, OPTISWITCH 5100 C, 5150 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 5100 C, 5150 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 a malfunction is detected or in case of power failure, the
electronics takes on a defined switching condition, i.e. the
output transistor blocks (safe condition).
Physical principle
Power supply
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.
OPTISWITCH 5100 C, 5150 C is 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 directly activated (e.g. a warning system, a PLC,
a pump etc.).
The exact range of the power supply is stated in the "Technical
data" in the "Supplement".
3.3 Operation
The switching condition of OPTISWITCH 5100 C, 5150 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.

4.1 General instructions
Switching point
In general, OPTISWITCH 5100 C, 5150 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
5100 C, 5150 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.

condensation water can thus drain off. This applies mainly to
mounting outdoors, in areas where moisture is expected (e.g.
by cleaning processes) or on cooled or heated vessels.
Fig. 6: Measures against moisture penetration
Transport
Pressure/Vacuum
Handling
Do not hold OPTISWITCH 5100 C, 5150 C on the tuning fork.
Particularly with flange or tube versions, the tuning fork can be
damaged by the instrument weight. Transport coated instruments very carefully and avoid touching the tuning fork.
Remove the protective cover just before mounting.
The process fitting must be sealed if there is gauge or low
pressure in the vessel. Before use, check if the seal material is
resistant against the measured product and the process
temperature.
The max. permissible pressure is stated in the "Technical
data" in the "Supplement" or on the type label of the sensor.
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 in the instrument!
Applying tightening force on the housing can damage its
internal mechanical parts.
To screw in, use the hexagon above the thread.

4.2 Mounting instructions
Mounting
Welded socket
OPTISWITCH 5100 C, 5150 C has a defined thread starting
point. This means that every OPTISWITCH 5100 C, 5150 C is
in the same fork position after being screwed in. Remove
therefore the supplied seal from the thread of OPTISWITCH
5100 C, 5150 C. 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
instrument versions.
Screw OPTISWITCH 5100 C, 5150 C 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 OPTISWITCH 5100 C, 5150
C 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, aligned with the
direction of flow.

Fig. 7: Marking on the welded socket
1 Marking
Adhesive products
In case of horizontal mounting in adhesive and viscous
products, the surfaces of the tuning fork should be vertical in
order to reduce buildup on the tuning fork. On the screwed
version you will find a marking on the hexagon. With this, you
can check the position of the tuning fork when screwing it in.
When the hexagon touches the seal, the thread can still be
turned by approx. half a turn. This is sufficient to reach the
recommended installation position.
With flange versions, the fork is directed to the flange holes.
30427-EN-060831
OPTISWITCH 5100 C, 5150 C - with transistor output 13
Page 14
Mounting
When used in adhesive and viscous products, the tuning fork
should protrude into the vessel to avoid buildup. For that
reason, sockets for flanges and mounting bosses should be
avoided when mounting horizontally.
Inflowing medium
Flows
If OPTISWITCH 5100 C, 5150 C is mounted in the filling
stream, unwanted switching signals may be generated. Mount
OPTISWITCH 5100 C, 5150 C at a location in the vessel
where no disturbing influence from e.g. filling openings,
agitators etc. can occur.
To minimise flow resistance caused by the tuning fork,
OPTISWITCH 5100 C, 5150 C should be mounted in such a
way that the surfaces of the blades are parallel to the product
movement.

With the mode adjustment (A/B) you can change the switching
condition of the relay. You can set the required mode acc. to
the "Function chart" (A - max. detection or overfill protection, B
- min. detection or dry run protection).
With this DIL switch (3) you can set the switching point to
liquids having a density between 0.5 and 0.7 g/cm³ (0.018 and
0.025 lbs/in³). With the basic setting, liquids with a density of
>0.7 g/cm³ (>0.025 lbs/in³) can be detected. In liquids with
lower density
, you must set the switch to >0.5 g/cm³
(>0.018 lbs/in³). The specifications for the position of the
switching point relate to water - density value 1.0 g/cm³
(0.036 lbs/in³). In products with a different density, the
switching point will shift in the direction of the housing or tuning
fork end depending on the density and type of installation.
