2.1 Hazards and Safety Measures
•Read this manual thoroughly and completely before working with the prod-
uct.
•Keep this manual in a safe place so that it is accessible to all users at all
times.
2.2 Intended Use
The measuring system LB 571 has been designed to determine the water or mois-
ture content or the concentration of almost any bulk material.The resonance
microwave measurement technique employed enables precise moisture online
measurement.
You act in compliance with the intended use if you:
•strictly adhere to the instructions and action sequences and do not carry out
any unauthorized actions that endanger your safety and the functionality
of the system!
•observe all specified safety instructions!
•carry out, or have carried out, the required maintenance work!
•only use Berthold accessories and spare parts.
The following is not in compliance with the intended use and
must be prevented:
•Failure to observe the safety instructions and information on operation,
maintenance and disposal provided in the operating instructions.
•Failure to observe the operating instructions for the delivered products.
•Use under terms and conditions other than those stated by the manufac-
turer in their technical documentation, data sheets, operating and
installation manuals and other specifications.
•Use of the product or parts thereof that are damaged or corroded. This also
applies to the seals and cables used.
•Modifications and changes to the system components.
•The product is not suitable for use in potentially explosive atmospheres and
must therefore not be operated in such areas. The product is not explosion-
proof.
•Operation in a state where live parts are accessible.
•Operation without observing the manufacturer’s recommended safety pre-
cautions.
•Manipulating or bypassing existing safety devices.
Berthold is liable and guarantees only that the device complies with its published
specifications. If the product is used in a manner that is not described in this user's

3System Description
The LB 571 microwave resonator for moisture measurement in real time has an
integrated evaluation unit and is commissioned and calibrated using PC software.
The resonator is kept at constant temperature by using PTC heaters inside device.
•Sensor and electronics form one unit
•Analog output signal directly from the sensor (4 ... 20 mA)
•Digital inputs
•Several calibration curves
•Measuring range: 0...30 % moisture
•Temperature range: 0...65 °C
3.1 Overview
An overview of the resonator with its external dimensions and connections are ex-
plained in this chapter. Mechanical installation and depth adjustment of resonator
is done by using a separate process installation flange around the resonator.

68847BA2 Rev.00, 10/2020
3.2 Measuring Principle
Microwaves penetrate the bulk material, causing a rotation of the free water mol-
ecules. Placing a moist material on the field of the sensors causes a decrease of the
resonance frequency and quality factor of the resonator. Both effects are measured
and used as a direct indication of the moisture content.
The resonator consists of a ceramic disc, which is embedded in a metal plate. The
upper side of the ceramic remains without a metal layer. From this side, the elec-
tromagnetic field interacts with the product to be measured. The measured data
are processed in the integrated evaluation unit and output as a measurement sig-
nal.

Conveyor belt
(gliding carriage)
The resonator can be mounted on a conveyor belt for
measurement. The contact with the bulk material must
be even and at a constant height.
Sliding plate
For example, the resonator can be installed under a silo
on a material slide.
Screw conveyor
The resonator can be attached to a tube of a screw con-
veyor by means of a flange.
NOTE
With bulk goods that are transported by screw conveyor, there is a possibility
that material will stick to the measuring position. Therefore remove a part of
the separating spiral or replace the part with a plastic part.

5.2 Cables and wires
Only use cables whose diameters are permissible for the respective cable gland. The
cables must meet the requirements and wire cross-sections specified in the tech-
nical data.
The connected cables must be suitable for a temperature which is at least 10°C
above the maximum permissible ambient temperature.
•Carry out the line connection with special care.
•The connecting cable and its installation must comply with the applicable
regulations.
•When laying the cables, make sure that mechanical damage to the conduc-
tor insulation on sharp-edged or moving metal parts is excluded.
•Use the Berthold approved cable or a cable with equivalent specifications
for connection.
Lay the connecting cables in such a way that
•no dirt or moisture gets into the terminal compartment,
•the conductors are not damaged during stripping,
•the conductor insulation or the collar of the ferrule extends into the housing
of the terminal body,
•bare conductive parts of the cables (e.g. wires of a stranded wire) do not
protrude from the terminal body,
•the length of the ferrule or stripped wire is 8 mm so that the wire is held
securely in the clamp,
•all strands are pressed with a ferrule,
•the conductor insulation extends into the collar of the ferrule,
•the minimum permissible bending radii for the respective conductor cross-
section are not undershot,
•the cables are strain-relieved and installed without abrasion.
Cable glands and dummy plugs
•Cables may only be fed into the wall housing via a cable entry.
•The screw connections must be suitable for the respective application.
•All cable glands must be fitted according to the manufacturer's instructions
and tightened to the appropriate tightening torque (cable gland M20 =
5.5 Nm).
•The feedthroughs not required for installation must be closed with suitable
dummy plugs.
•The permissible cable cross-section must be matched to the cable used.
•The cable conduits and dummy plugs must be designed to meet the appli-
cable protection level requirements or the requirements of the operating
environment.
•We recommend ordering missing fittings, dummy plugs or adapters from
Berthold.
