3.2 Principle of operation
The NivoGuide 8100 is a level sensor with coax probe for continuous
level or interface measurement, suitable for applications in liquids.
Due to the qualication up to SIL2 or homogeneous redundant up to
SIL3 (IEC 61508) the NivoGuide 8100 is suitable for the use in safety-
instrumented systems (SIS).
The safety function (SIF) can be a monitoring of the max. or min. level
or a combination of both.
High frequency microwave pulses are guided along a steel cable or
a rod. Upon reaching the product surface, the microwave pulses are
reected. The running time is evaluated by the instrument and output
as level.

High frequency microwave impulses are guided along a steel cable or
rod. Upon reaching the product surface, a part of the microwave im-
pulses is reected. The other part passes through the upper product
and is reected by the interface. The running times to the two product
layers are processed by the instrument.

4.1 General instructions
On devices with a threaded tting, the hexagon on the process tting
must be tightened with a suitable wrench.
See chapter "Dimensions" for wrench size.
Warning:
The housing or the electrical connection may not be used for screw-
ing in! Depending on the device version, tightening can cause dam-
age, e. g. to the rotation mechanism of the housing.
Protect your instrument against moisture ingress through the following
measures:
• Use a suitable connection cable (see chapter "Connectingto
power supply")
• Tighten the cable gland or plug connector
• Lead the connection cable downward in front of the cable entry or
plug connector
This applies mainly to outdoor installations, in areas where high
humidity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
Note:
Make sure that the degree of contamination specied in chapter
"Technical data" meets the existing ambient conditions.
Note:
Make sure that during installation or maintenance no moisture or dirt
can get inside the instrument.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
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. The dust protection caps do
not provide sucient protection against moisture.
Prior to setup you have to replace these protective caps with ap-
proved cable glands or close the openings with suitable blind plugs.
Note:
For safety reasons, the instrument must only be operated within the
permissible process conditions. You can nd detailed information on

the process conditions in chapter "Technical data" of the operating
instructions or on the type label.
Make sure before mounting that all parts of the instrument exposed to
the process are suitable for the existing process conditions.
These are mainly:
• Active measuring component
• Process tting
• Process seal
Process conditions in particular are:
• Process pressure
• Process temperature
• Chemical properties of the medium
• Abrasion and mechanical inuences
4.2 Mounting instructions
In vessels with conical bottom it can be advantageous to mount the
sensor in the center of the vessel, as measurement is then possible
nearly down to the lowest point of the bottom. Keep in mind that
measurement all the way down to the tip of the probe may not be pos-
sible. The exact value of the min. distance (lower dead zone) is stated
in chapter "Technical data".
Fig. 4: Vessel with conical bottom
Before beginning the welding work, remove the electronics module
from the sensor. By doing this, you avoid damage to the electronics
through inductive coupling.
Do not mount the instruments in or above the lling stream. Make sure
that you detect the product surface, not the inowing product.

61893-EN-190911
Fig.5:Mountingofthesensorwithinowingmedium
The reference plane for the measuring range of the sensors is the
sealing surface of the thread or ange.
Keep in mind that a min. distance must be maintained below the refer-
ence plane and possibly also at the end of the probe - measurement
in these areas is not possible (dead zone). These dead zones are
listed in chapter "Technical data". Keep in mind for the adjustment that
the default setting for the measuring range refers to water.
The process tting 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 specied in chapter "Technical
data" or on the type label of the sensor.
If there is a risk of the coaxial probe touching the vessel wall during
operation due to product movements or agitators, etc., the measuring
probe should be securely xed.
Avoid undened vessel connections, i.e. the connection must be
either grounded reliably or isolated reliably. Any undened change of
this condition can lead to measurement errors.
If there is a danger of the coaxial probe touching the vessel wall, then
the probe must be fastened at the bottom end.
Keep in mind that measurement is not possible below the fastening
point.

5.1 Preparing the connection
Always keep in mind the following safety instructions:
• Carry out electrical connection by trained, qualied personnel
authorised by the plant operator
• If overvoltage surges are expected, overvoltage arresters should
be installed
Warning:
Only connect or disconnect in de-energized state.
Power supply and current signal are carried on the same two-wire
cable. The operating voltage can dier depending on the instrument
version.
The data for power supply are specied in chapter "Technical data".
Provide a reliable separation between the supply circuit and the
mains circuits according to DIN EN 61140 VDE 0140-1.
Power the instrument via an energy-limited circuit acc. to IEC 61010-
1, e.g. via Class 2 power supply unit.
Keep in mind the following additional factors that inuence the operat-
ing voltage:
• Lower output voltage of the power supply unit under nominal load
(e.g. with a sensor current of 20.5 mA or 22 mA in case of fault)
• Inuence of additional instruments in the circuit (see load values in
chapter "Technical data")
The instrument is connected with standard two-wire cable without
screen. If electromagnetic interference is expected which is above the
test values of EN 61326-1 for industrial areas, screened cable should
be used.
Use cable with round cross section for instruments with housing and
cable gland. Use a cable gland suitable for the cable diameter to
ensure the seal eect of the cable gland (IP protection rating).
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.
Note:
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.

61893-EN-190911
Note:
Prior to setup you have to replace these protective caps with ap-
proved cable glands or close the openings with suitable blind plugs.
On plastic housings, the NPT cable gland or the Conduit steel tube
must be screwed into the threaded insert without grease.
Max. torque for all housings, see chapter "Technical data".
If screened cable is required, we recommend connecting the cable
screening on both ends to ground potential. In the sensor, the cable
screening must be connected directly to the internal ground terminal.
The ground terminal on the outside of the housing must be connected
to the ground potential (low impedance).
In Ex systems, the grounding is carried out according to the installa-
tion regulations.
In electroplating plants as well as plants for cathodic corrosion protec-
tion it must be taken into account that signicant potential dierences
exist. This can lead to unacceptably high currents in the cable screen
if it is grounded at both ends.
Information:
The metallic parts of the instrument (process tting, sensor, concen-
tric tube, etc.) are connected with the internal and external ground
terminal on the housing. This connection exists either directly via
the conductive metallic parts or, in case of instruments with external
electronics, via the screen of the special connection cable.
You can nd specications on the potential connections inside the
instrument in chapter "Technical data".
5.2 Connecting
The voltage supply and signal output are connected via the spring-
loaded terminals in the housing.
Connection to the display and adjustment module or to the interface
adapter is carried out via contact pins in the housing.
Information:
The terminal block is pluggable and can be removed from the
electronics. To do this, lift the terminal block with a small screwdriver
and pull it out. When reinserting the terminal block, you should hear it
snap in.
Proceed as follows:
1. Unscrew the housing lid
2. If a display and adjustment module is installed, remove it by turn-
ing it slightly to the left
3. Loosen compression nut of the cable gland and remove blind
plug
4. Remove approx. 10 cm (4 in) of the cable mantle, strip approx.
1 cm (0.4 in) of insulation from the ends of the individual wires
5. Insert the cable into the sensor through the cable entry
