contamination can result. Also, the protective characteristics of the
instrument can be impaired.
2.4 General safety instructions
This is a state-of-the-art instrument complying with all prevailing
regulations and directives. The instrument must only be operated in a
technically awless and reliable condition. The operator is responsi-
ble for the trouble-free operation of the instrument. When measuring
aggressive or corrosive media that can cause a dangerous situation
if the instrument malfunctions, the operator has to implement suitable
measures to make sure the instrument is functioning properly.
During the entire duration of use, the user is obliged to determine the
compliance of the necessary occupational safety measures with the
current valid rules and regulations and also take note of new regula-
tions.
The safety instructions in this operating instructions manual, the na-
tional installation standards as well as the valid safety regulations and
accident prevention rules must be observed by the user.
For safety and warranty reasons, any invasive work on the device
beyond that described in the operating instructions manual may be
carried out only by personnel authorised by the manufacturer. Arbi-
trary conversions or modications are explicitly forbidden. For safety

2.5 EU conformity
The device fulls the legal requirements of the applicable EU direc-
tives. By axing the CE marking, we conrm the conformity of the
instrument with these directives.
The EU conformity declaration can be found on our homepage.
Electromagnetic compatibility
Instruments in four-wire or Ex-d-ia version are designed for use in an
industrial environment. Nevertheless, electromagnetic interference
from electrical conductors and radiated emissions must be taken into
account, as is usual with class A instruments according to EN 61326-
1. If the instrument is used in a dierent environment, the electromag-
netic compatibility to other instruments must be ensured by suitable
measures.
2.6 SILqualicationaccordingtoIEC61508
The Safety Integrity Level (SIL) of an electronic system is used to as-
sess the reliability of integrated safety functions.
For detailed specication of the safety requirements, multiple SIL
levels are specied according to safety standard IEC 61508. You can
nd detailed information in chapter "Functional safety (SIL)" of the
operating instructions.
The instrument meets the specications of IEC 61508: 2010 (Edi-
tion 2). It is qualied for single-channel operation up to SIL2. The
instrument can be used homogeneously redundant up to SIL3 in
multi-channel architecture with HFT 1.
2.7 NAMUR recommendations
NAMUR is the automation technology user association in the process
industry in Germany. The published NAMUR recommendations are
accepted as the standard in eld instrumentation.
The device fulls the requirements of the following NAMUR recom-
mendations:
• NE 21 – Electromagnetic compatibility of equipment
• NE 43 – Signal level for fault information from measuring transduc-
ers
• NE 53 – Compatibility of eld devices and display/adjustment
components
• NE 107 – Self-monitoring and diagnosis of eld devices
For further information see www.namur.de.

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 qualication 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
reected. 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 reected. The other part passes through the upper product
and is reected by the interface. The running times to the two product
layers are processed by the instrument.

Upper medium (L2)
• The upper medium must not be conductive
• The dielectric constant of the upper medium or the actual distance
to the interface must be known (input required). Min. dielectric
constant: 1.6.
• The composition of the upper medium must be stable, no varying
products or mixtures
• The upper medium must be homogeneous, no stratications
within the medium
• Min. thickness of the upper medium 50 mm (1.97 in)
• Clear separation from the lower medium, emulsion phase or detri-
tus layer max. 50 mm (1.97 in)
• If possible, no foam on the surface
Lower medium (L1)
• The dielectric constant must be 10 higher than the dielectric
constant of the upper medium, preferably electrically conductive.
Example: upper medium dielectric constant 2, lower medium at
least dielectric constant 12.
Gas phase (L3)
• Air or gas mixture
• Gas phase - dependent on the application, gas phase does not
always exist (d2 = 0)
