2.3 Intended Use
The LB 566 can be used to determine the water or moisture
content and the concentration of virtually any material. The following sensors and evaluation versions are available:
1. The container probes have been designed for installation into containers and pipelines with a nominal width of 200
mm. The probe is mounted so that both measuring rods
(transmitter and receiver) are immersed into the product
being measured.
2. The FlowCell is a tubular probe, with the microwave transmitter and receiver being firmly welded onto the outside of
the tube. The tube is lined with Teflon to ensure smooth
walls. The FlowCell is either installed directly into the existing pipeline system or into a bypass.
The evaluation unit is available in two versions: The standard
model MicroPolar and the high dynamic version MicroPolar ++.
The Micro Polar ++ requires a microwave signal attenuation of
at least 40 dB. The MicroPolar must be used for lower microwave attenuation.
During operation, the concentration meters MicroPolar and MicroPolar ++ emit electromagnetic radiation in the frequency
range between 2.4 GHz and 2.5 GHz (range limitations depending on local regulations in your country). Microwaves are not
dangerous to human beings and the environment (power radiation < 10 mW). The microwaves are emitted directed from the
microwave window; the product is not altered by the microwaves.
To ensure proper function of the measuring system, please pay
attention to the following:
TIP
The material to be measured may be electrically conduc-
tive only to a limited degree.
The product must not contain any gas bubbles or gas
bubbles have to be compressed with adequate pressure
when carrying out measurements in pipelines.
The ion concentration, for example, salt content must be
nearly constant.

3.1 Principle of Measurement
As the microwaves pass through the product, their propagation
velocity is slowed down (= phase shift) and their intensity is attenuated (= attenuation). Figure 3-1 illustrates the principle of
measurement: Compared to a reference signal, the propagation
velocity of microwaves passing through the product is slowed
down (phase shift) and their intensity (attenuation) is reduced.

The prerequisite is that the product being measured shows dielectric properties. Generally, water is a very distinct dielectric
fluid. The water or dry mass concentration can therefore be determined by measuring the phase shift and/or attenuation.
The concentration to be detected in the product is therefore in
good approximation linearly dependent on the phase shift and
the attenuation. For this reason, we can measure the concentration or the dry matter content of the product using a linear
calibration (see chapter 3.2 Calculation of Measured Values).

Change in

Chapter 3. System Description
18 MicroPolar (++) LB 566
3.2 Calculation of Measured Values
The microwave parameters phase and attenuation are calibrated according to an automatic plausibility analysis.
During calibration, the phase and/or attenuation of a concentration value (or density value) are assigned through sampling.
The calibration is done automatically and the sampling process
is supported by the evaluation unit.
Which of the parameters (phase, attenuation or both) will be
used for the calibration depends on the size and interference of
the measuring effect. For example, the attenuation is significantly more sensitive to electrolytic conductivity (salt content).
In many cases, the pure phase measurement is recommended
and the measured value is calculated as follows:
Measured value = A ∙ Phase + C Eq. 3-1
where:
Measured value Concentration / Moisture / Dry matter
A, C Coefficients of the respective calibration
function
The LB 566 allows you to calibrate, display and output two concentrations: Con1 and Con2. You have to enter the calibration
coefficients separately for concentration 1 and 2. For more information please refer to the Software Manual.
Limitations
Weakly bound water can be detected depending on the
strength of the binding. Thus, the measuring effect may be
dependent on the grain size distribution and the chemical
properties of the product being measured, provided this
changes the binding of water to the solid matter.
Walls made of plastic, rubber or insulation materials with
fairly low dielectricity hardly affect the measurement and are
calibrated at a constant level.
Ice and crystal water cannot be measured because the water
molecules cannot rotate freely (ice and crystal water are
dry).
Chapter 3. System Description
MicroPolar (++) LB 566 19
Conductive materials such as graphite or coke cannot be transmitted by microwaves. Metal walls can also not be transmitted
by microwaves.
Compensation In addition to the water content, the product temperature,
product density and a varying material load (varying microwave
irradiation path) may have an influence on the phase and attenuation. This influence has to be compensated for during calibration.
3.3 Temperature Compensation
Temperature compensation (TC) is required for fluctuating
product temperature. It is generally advisable to provide a temperature compensation, i.e. a temperature signal (0/4...20 mA
or PT100) to be connected to the evaluation unit and, optionally, to enable the compensation in the evaluation unit. The evaluation unit is designed so that the required TC’s can be calculated automatically. The variation in temperature where TC becomes absolutely essential is dependent on the product and on
the water content. In the first approximation, 2° C should be
set as fluctuation limit.
For example, if the product temperature is measured via the
PT100 input, then Eq. 3-1 is expanded as follows:
Measured value = A · Phase + D · T
meas
+ C Eq. 3-2
where:
Measured value Concentration / Moisture / Dry matter
A, D, C Coefficients of the calibration function

Product temperature
How to work with the temperature compensation is described in
detail in the Software Manual.
Chapter 3. System Description

3.4 Throughput Calculation and Output
For pipeline applications, the LB 566 allows you to calculate the
throughput (mass flow) and to output the result via a current
output.
The calculation is based on the microwave measured value; if
this value correlates with the product density, one can calculate
the throughput, if some additional information is available. The
additional information needed is: internal pipe diameter/cross
section and the product speed. The product speed has to be fed
via current input.
For details, please see the Software Manual, chapter 4.2.12
Mass Flow.

3.5.1 Evaluation Units
The evaluation units comprise the evaluation computer and the
microwave unit. The microwaves are generated, received and
analyzed in the microwave unit. Signal processing and communication take place in the evaluation computer. For simple operation, the measuring system includes a display, 4 softkeys and
an alphanumeric keypad. Different functions are assigned to the
softkeys on the display.
Differences between MicroPolar ++ und MicroPolar
The MicroPolar ++ evaluation unit has an additional HF amplifier
module in comparison to the standard model; therefore, it also
has a larger wall housing (dimensions see chapter 6.1 Technical
Data Evaluation Unit). Otherwise, the evaluation units differ only in their application.
MicroPolar ++ The high dynamics version MicroPolar ++ permits higher
product attenuations. Larger measuring paths can be irradiated,
i.e. flow cells with larger nominal diameters can be used. Which
type of evaluation unit is used depends on the product attenuation. MicroPolar is used up to an attenuation of 50 dB; MicroPolar ++ is used for higher attenuations. The MicroPolar ++ generally requires an attenuation of 40 dB. If this attenuation is not
reached, the software displays an error message.

Chapter 3. System Description
26 MicroPolar (++) LB 566
The flow cell consists of a sturdy stainless steel body. The microwave transmitter and receiver are firmly welded to the outside of the pipe. The entire product pipe is PTFE-coated and
thus meets the special requirements for use in food for use in
food.
There are no objects that extend into the pipe (e.g. a measuring
sensor). Depending on the version, the FlowCell can be mounted with the V flange or milk pipe screw connection to the piping.
For the versions with V flange, ASA adapter flanges are available as accessory.
The FlowCell has two HF ports to feed in and output the microwave signals. The input and output can be allocated as needed
(M-Tx, M-Rx). The microwave signals transmit the product over
the entire pipeline cross-section.
For all versions, the following accessories are available:
1. Pipe-mounted PT100 or Inline PT100
2. Conductivity measuring device
3. Sampling valve

3.5.4 Container Probe
The container probe is available in a version with and without
flushing device (see Figure 3-12). The technical data are listed
in chapter 6.2 Technical Data Sensors.
A: High-frequency connections
B: Process connection, flanges of different sizes
Container probe type LB 5650 and type LB 5651
The container probe has been specially designed for concentration measurements in containers. Both measuring rods are immersed into the product. Microwaves are emitted from one end
of the rod and received by the other end of the rod; they are
emitted only towards the opposite end of the rod. This directional characteristic of the probe minimizes the interfering influence of metal parts in the vicinity of the probe and allows installation if only limited space is available. For example, the concentration of sugar strike can be measured continuously to find
the suitable inoculation time.
The plastic caps of the measuring rods meet the special requirements for application in foodstuffs.
Two different probe types are available:
The standard type is the container probe without flushing
device.
The flushing probe is used in processes where incrustations
are likely to occur, for example, due to increased depositions. The flushing device prevents deposition on the microwave exit windows.
Figure 3-12:
Container probe
versions
Chapter 3. System Description
28 MicroPolar (++) LB 566
For the case depicted in Figure 3-13, the flow direction of the
product being measured must be perpendicular to the drawing
plane. This ensures a representative product between the
measuring rods, provided the product is mixed thoroughly.
The container probe LB 5650 is the only one equipped with a
PT100 connection and can be connected to the evaluation unit
via a 4-core cable. The PT100 wiring diagram is described in
chapter 4.6.1 Pin Configuration of the Connector Strip. To minimize the danger of incrustation in the immediate vicinity of the
measuring rods, the container flush probe is not provided with a
PT100.
Warning: Possible material damage!
Do not open the cover screws on the front of the container
probes, see Figure 3-14.

Container probe type LB 5651 with flushing device
The flushing probe LB 5661 has been designed for processes in
which depositions, for example, due to incrustations are likely to
occur on the probe.
The flushing probe has two flushing channels which keep the
measuring rods free from incrustations; this ensures that the
microwaves come into direct contact with the product being
measured. All probe parts coming into contact with the product
meet the special requirements for application in foodstuffs. Fig-
ure 3-15 shows the probe design.
The flushing slit width is the same for both probe rods and is
depicted in Figure 3-16.

3.5.5 High-frequency Cable
High-frequency cables (HF cable) are used to transmit microwave signals.
HF cables change their conductivity (for microwaves) with temperature and would therefore produce measurement errors with
varying ambient temperature. This error is compensated for by
enabling the automatic cable compensation. The influences of
the ambient temperature on the signal cable are compensated
for by means of the reference cable. To this end, the sum of the
reference cables has to match the length of the sum of the signal cables.
Two different HF cable types of different lengths are available:
Version 1: The so-called HF-cable quad: It consists of four single HF-cables of equal length, whose ends are terminated by
one HF-connector (N-type). Available cable lengths: 2, 4, 6 and
10 m (see Figure 3-17).
The HF-cable quad is used exclusively for the container probe
and the FlowCell. For the FlowCell, the reference line on the

3.6 Assembly on a Pipeline
The evaluation unit is installed close to the FlowCell to keep the
HF cable between evaluation unit and probe as short as possible. The shorter the cable connection, the better the stability of
the measurement. The standard length is 2 m and the maximum length of the HF cable is 10 m. The HF cable must be at
least 2 m long.
The FlowCell is integrated into the existing pipeline system or in
a bypass. The orientation of the FlowCell can either be vertical
or horizontal. To avoid possible sedimentary deposits, vertical
installation in a riser is preferred (see Figure 3-20).
The installation should preferably be close to a sample sampling
point to ensure representative sampling for calibration.
A representative temperature signal (current signal or PT100)
should be connected to the evaluation unit for product temperature compensation.

MicroPolar (++) LB 566 33
3.7 Assembly on a Container
The evaluation unit is installed in the immediate vicinity of the
container probe to keep the HF-cable between evaluation unit
and probe fairly short. The shorter the cable connection, the
better the stability of the measurement. The standard length is
2 m and the maximum length of the HF cable is 10 m. The HF
cable must be at least 2 m long.
The installation should preferably be close to a sampling point
to ensure representative sampling for calibration. A representative temperature signal (current signal or PT100) should be
connected to the evaluation unit for a possibly required product
temperature compensation.
Our example in Figure 3-21 shows the measurement configuration on a process container. The probe is fixed to the container
wall using a flange coupling so that both measuring rods are
immersed into the product.

4.1 Transport
Warning: Possible material damage!
System parts may get damaged during transportation!
Transport all components in their original packaging.
Protect parts against shocks.
In particular, the measuring rods of the container probes must
be protected against mechanical shock!
After unpacking, make sure all parts listed on the packing list
have been delivered and show no sign of damage; if necessary,
clean these parts.
If you detect any damage, please notify the forwarder and the
manufacturer immediately.
The weight of the system components may exceed 25 kg,
depending on the version. We recommend, therefore, that you
wear safety boots.
Chapter 4. Getting Started

4.2 Commissioning the FlowCell
4.2.1 Installing the FlowCell
Note the following points when installing the FlowCell:
The FlowCell is integrated at a suitable location in the pipe-
line system. Keep in mind that material sampling directly
behind the FlowCell should be possible for calibration.
The FlowCell should be installed in a vertical riser, if possi-
ble. It must be ensured that material deposits cannot form
on the pipe walls and no bubble formation occurs in the
product. In case of horizontal installation, please observe
the correct orientation of the HF connections, see Figure 4-
2.
There should be a straight pipe section of at least 300 mm
and equal nominal width before and after the FlowCell to ensure a fairly homogeneous flow profile and to rule out possibly occurring microwave reflections in the pipeline. Also, not
fittings must be installed in these pipe sections.
No gas inclusions should be present in the product. If gas
bubbles cannot be ruled out, a pressure of at least 4 bar is
required in the pipeline to minimize the influence of gas
bubbles. Please observe the max. permissible operating
pressure, see chapter 6.2 Technical Data Sensors.
The high-frequency cables should preferably be connected to
the FlowCell from below to prevent flowing water from getting to the connection sockets.
The signal and reference cable should as far as possible fol-
low the same path to make sure both cables are exposed to
the same temperature and should not come into contact
with hot pipelines. We recommend installing the HF cable
through a single protection tube. If you are working with the
HF cable quad, this function is taken over in good approximation by the corrugated tube.

4.2.2 Installing the Evaluation Unit
Note the following points when installing the evaluation unit:
Position the evaluation unit depending on the length of the
HF cable in the vicinity of the microwave probe.
The evaluation unit has to be protected against vibrations.
In some cases, it is advisable to set up the evaluation unit
on a stand separated from the pipeline system.
For instrument installation you should foresee a cutoff de-
vice to allow easy and quick disconnection of the device
from the power supply.
Provide an automatic separating device (line circuit breaker)
that disconnects the unit from power within 0.03 seconds in
case of failure. The separating device must be matched to
the cable cross-section of the supply line, but at least it
must be designed for 1 A continuous current.
When installing the evaluation unit on a crystallizer, use a
distance rail to minimize the thermal radiation and conduction. See Figure 4-3:
For outdoor applications, the evaluation unit must be pro-
tected from direct sunlight and rain, for example by a suitable shelter.

4.2.3 Connecting the HF Cable
The FlowCell is connected with the evaluation unit via the HF
cables. Two different options are available:
Version 1: 1 x HF cable quad and 1 x N-connector
Version 2: 2 x HF cables (as signal cable)
1 x HF cable (as reference cable)
The decision for a certain cable version is taken by Berthold
Technologies in the planning stage. It is subject to the application and the desired distance between evaluation unit and
FlowCell.
Prerequisite for a correct measurement is the correct installation
of cables! Please keep in mind:
TIP
Make sure the cable does not get into contact with hot pipes
over the entire length (corrugated tube and single cable
section after splitting), e.g. direct contact with the device wall
(not insulated). This will ensure that all individual cables are
exposed to the same ambient conditions and that the compensation of the cable drift works properly.
Never bend the HF cable! The bending radius should not be
less than 100 mm. Fix the HF cable with cable binders or other
suitable means, so that the cable cannot slip anymore!
During assembly, ensure that the end of the corrugated tube
is bent down on the probe side. By doing so, the ingress of
fluids into the corrugated tube is prevented.
Version 1 The HF cable quad and the HF connectors on the evaluation unit
are labeled. Connect the FlowCell to the evaluation unit as
shown in Figure 4-4; only cables with identical labeling can be
combined. The two connections on the FlowCell are not labeled,
the assignment of both cable connectors M-Tx and M-Rx is arbitrary. Connect the cable connectors R-Tx and R-Mx with the Nconnector (short-circuited).
Version 1 Connect the FlowCell to the evaluation unit as shown in Figure
4-5; make sure that the reference cable (ring line) is connected
to R-Tx and R-Mx.
The reference cable must be as long as the sum of both signal
cables.
Chapter 4. Getting Started
40 MicroPolar (++) LB 566
Hand tighten all screwed connections of the HF cable (2 Nm =
0.2 kg/m)! Before tightening, carefully screw on the cable by
hand. Caution! Threaded joint jams easily.
Check occasionally if the screwed connection is still properly
tightened. If the installation is exposed to vibrations, the
screwed connection may come loose and this may result in inaccurate measurements or corrosion of the connections.

MicroPolar (++) LB 566 41
As long as the cables are not connected, the coaxial sockets
have to be covered with plastic caps and the cable connectors
have to be protected against moisture and dirt.
4.3 Commissioning the Container Probe
4.3.1 Installing the Container Probe
For installation of the probes, please keep in mind:
Select the installation site such that good mixing and a ho-
mogeneous product are ensured and no bubbles are present
in the probe. A sample tap should be available in the direct
vicinity to allow representative sampling.
The probe must be flanged to the container so that the ma-
terial to be measured flows between the two measuring
rods. That means the fork (both measuring rods) must be
installed perpendicular to the material flow.
The distance between the measuring rod tips and any metal-
ized walls (heating element, stirrer, container wall) should
be at least 60 mm.
The following mounting hole dimensions in the fitting
flange are required for installation of the probe:
Flange Minimum mounting hole size (mm)
DN 65 / PN 6 102 0.3
others 104 0.5
For further installation dimensions, such as the required in-
stallation depth, please refer to chapter 8.6 and 8.7 Assem-
bly Sheets.
Use the appropriate flat gasket (standard accessory) to
compensate for minor surface tolerances in the fitting
flange.
Installation on process containers
Figure 3-26 shows the position of the container probe on the
container. This position is also valid for the container flush
probe. Follow the instructions in chapter 3.9 Assembly on a
Container.
The assembly sheets in chapters 8.6 and 8.7 include all the information required for installation.
Depending on the process, the probe flange may stick to the
process flange. In such case, during the dismounting process,
Dismounting in the
event of a stuck
flange
Chapter 4. Getting Started
42 MicroPolar (++) LB 566
remove the two eyebolts first. Then insert two longer screws
(M8) into their bore holes up to the process flange. If you continue to rotate the screws, you will push the probe away from
the process flange.
Installation in pipelines
Container probes can be installed in pipelines with a nominal
width 200 mm using an adapter flange. Note the position and
orientation of the container probe, see the technical drawings in
chapter 8.4.7 and 8.5.6 Installation Situation in Pipelines.
Connecting the flushing pipes
The container probe with flushing device has two flushing connections with G3/8'' female thread (DIN ISO 228-1). The flushing connections should be sealed only at this thread. Sealing the
probe cover, for example with silicone, is not permitted.
Flushing parameters (only for flushing probe)
The degree of deposition or incrustation is essential for the flush
settings, i.e. flush interval and flush duration. The flushing parameters must be matched to the product and the process.
The following product and process independent flushing parameters must be strictly adhered to:
Flush solution Water, condensate
Temperature of
flush solution
Maximum 120°C
Pressure
3 bar, max. 8 bar
Fittings 2 x G3/8'' female thread (DIN ISO 228-1)
Supply pipe
1/2 inch
In general: The flushing connections can be flushed simultaneously or sequentially. The flushing parameters are valid for each
flushing connection.
TIP
The required flush duration has to take into account possible
inertias of the system, e.g. valve openings. The flush supply
pipes must be well insulated to prevent that the flush solution
is initially colder.
Amounts of water With a 5 bar flushing pressure, the amount of water per flushing
connector is approximately 0.8 liters per second.

Service instructionsChapter 5.
5.1 General Information
A malfunction of the measuring system is not always due to a
defect in the instrument. Often the error is caused by incorrect
operation, improper installation or irregularities in the product
being measured. If a malfunction occurs, anyway, the measuring system helps you to identify and eliminate errors by displaying error messages on the display, indicating operator errors
and defects of the electronics.
Defective modules of the evaluation unit cannot usually be repaired but must be replaced. The microwave module is firmly
bolted to a screening hood and must not be opened.
For device disposal, please contact the Berthold Service and apply for a recycling passport.
Chapter 5. Service instructions
52 MicroPolar (++) LB 566
5.2 Wear Parts
The evaluation unit does not include any parts that are subject
to wear or components that require special maintenance.
The plastic caps of the measuring rods of the container probes
and the PEEK Microwave window of the flow cell may be subject
to abrasion over the course of time. A low to medium abrasive
influences the measurement only very little and can be compensated for by a calibration. Therefore, check the wear parts in intervals of about 2 years. In case of heavy wear, the plastic caps
of the measuring rods of the container probe and the PEEK Microwave window of the flow cells can be replaced.
The plastic caps of the measuring rods can be replaced on site.
For this purpose, please proceed as follows:
1
Unscrew the two plastic caps from the measuring rods and
remove the four sealing rings (see figure 5-1, yellow arrow).
2
Clean the four grooves of the sealing rings with a lint-free (if
necessary wet) cloth.
3
For each measuring rod, insert two new sealing rings into
the grooves.
4
Screw on the two new plastic caps.

5.3 Instrument Cleaning
Clean all system components exclusively with a damp cloth with
no chemical cleaning agent. Parts coming into contact with the
product (during regular operation) can be cleaned with warm
water, taking into account the temperature limits, see chapter
6.2 Technical Data Sensors.
5.4 Battery
If the measuring system LB 566 is a long time without power
supply (power failure or disconnected from the mains supply),
the system clock is powered by the lithium battery on the
motherboard.
If the battery voltage is no longer sufficient, the error message
CODE 14 "Battery voltage" appears after a restart of the evaluation unit. After acknowledging the error message, the unit
continues to work properly; however, the date and time should
be checked and corrected, if necessary. Measurement data that
are output via a serial interface can be fatally damaged by incorrect date and time information. We recommend changing the
batteries immediately.
The service life of the battery, even under continuous stress, is
approximately 8 years. Replacement of batteries must be carried out in a device disconnected from mains.
