Conveyor-belt scales
by Pfreundt:
Precise weighing on conveyor belts
Practical technology in use around the globe
For more than 25 years, PFREUNDT has consistently pursued the ambitious goal of further
developing trusted technologies to make them even more effective. The result: numerous
practical innovations and patented solutions that are employed worldwide under the
harshest conditions.
Exact weight values under the harshest
conditions
Even under rough conditions such as in quarries, conveyor-belt scales
made by PFREUNDT guarantee the maximum degree of precision.
They are rugged, exceptionally compact and can be installed or
retrofitted on nearly any conveyor belt. The measurement of conveyor-belt
speed, a standard feature located directly on the belt, ensures precise
data – even when there is belt slip on drive or return pulleys.
PFREUNDT conveyor-belt scales have proven themselves in both mobile
and static applications. Whether in crushers, screening machines and
conveyor belts in the mining industry, mobile employment such as in
road milling machines or surface miners, agricultural equipment such as
beet loading machines or in the sorting and waste treatment facilities
of the waste disposal sector – they have been working for years with
precision and reliability.
A scale custom-tailored to match your needs
At PFREUNDT, customer service means an uncompromising focus on
the demand for precision, speed, ease of use and durability. PFREUNDT's
solutions are custom-made for each weighing task and bring immediate
profits.
With various models, electronics and an extensive range of accessories,
each weighing system can be tailored exactly to meet your needs,
offering optimal operational convenience, as well as far-reaching
control over the weighings.
The optional inclinometer automatically corrects the weighing system
for changes in the angle of the conveyor-belt discharge – ensuring
precise measurement in mobile applications, in particular.
If needed, we can provide official calibration for static conveyor belts,
while also covering the remaining requirements of the Office of
Weights and Measures.
If you choose, you can evaluate several discharge conveyor belts by using
only one weighing electronics or represent the data visually by using the
PFREUNDT software “CWM Conveyor-belt scale” on a PC. To do this, the
weighing frames in the individual conveyor belts are equipped with
PFREUNDT CAN weighing modules and then networked with weighing
electronics or with the PC.

NEW
In the new BW-2 S for static
applications, you have a low-priced
weighing system that you can
assemble yourself.
For static conveyor belts with a standard
frame width of up to 1150 mm (45 in.) or
1600 mm (63 in.).
Easy self-assembly
You can easily assemble the BW-2 S yourself.
In this way you save on additional service personnel,
doubling the value of your weighing system.
Mechanic pre-assembled
You can easily install the pre-assembled components by
following the clearly laid out instructions.
Electronics pre-installed
A prefabricated cable with plugs permits the straightforward
connection of the sensor to the WK 50-S BW evaluation unit –
the electronics need not even be opened.
System pre-calibrated
The weighing electronics are pre-set in our factory.
All you need to do is set a few belt parameters and the scale
is independently precise and ready to be employed.
When needed, you can further optimize the measured values
in the installed scales by running comparative weighings and
by fine-tuning the electronics.
Clear instructions are included in
the scope of supply.
You can however – as is the case for all PFREUNDT weighing
systems – prefer to have one of our service technicians install
and adjust the BW-2 S. The extensive service network of our
own employees means that we are always within easy reach.
• You will find options and accessories listed on page 5
Standard scope of supply BW-2 S
(Weighing frame 1150 or 1600 mm –
depending on the conveyor belt)

Options – exclusive to BW-2:
The inclinometer for mobile
applications and the CAN weighing
module for connecting several
weighing frames to one weighing
electronics are placed securely in a
stable aluminum wiring box. If
needed a robust plug connection
can be mounted here.
Weighing and master data can be
exchanged between the weighing
electronics and the PC by a GSM
modem or by radio.
Rather than using GSM or radio,
data transfer can also be
accomplished using the memo box.
For data transfers it is hooked up
alternately to the serial interfaces
(RS232) of the weighing electronics
and the PC.
• Additional options and accessories
are listed on page 5
The BW-2 is a robust weighing system for static and
mobile applications for standard frame widths from
800 mm (31.5 in.) to 1600 mm (63 in.) . Master and
weighing data memories as well as an extensive range
of options, allow for many different kinds of evaluation
as well as for data transfer and processing.
Also for mobile application
The BW-2 with optional inclinometer is the ideal
weighing system for use in mobile devices such as crushers
and screening machines. Even in road milling
machines, surface miners and agricultural machinery
such as beet loading machines, the BW-2 consistently
delivers exact weight values.
Full control through WK 50
The weighing electronics WK50 included in the scope of
supply offers extensive master and weighing data
memory as well as interfaces, e.g. for data exchange
with the control room. This may be done by GSM, radio
or memo box for example, automatically at night, which
makes the WK 50 the ideal solution for rapid processing
of weighing data in your EDP. Furthermore with an
optional statistical program you can also evaluate
performance data.
Approval for static conveyor belts
When needed, we are able to offer the BW-2 to you as
an officially calibrated weighing system for static
conveyor belts, which meet the requirements of the
Office of Weights and Measures.
Weighing electronics for several conveyor
belts
By using PFREUNDT CAN weighing modules, several
conveyor-belts equipped with weighing frames can
be evaluated while using only one WK 50 weighing
electronics.
We provide the PFREUNDT Office Software P.O.S. in program modules for the P.C.
– adapted to your needs. The software can be used as a pure communications
interface for client-side user programs, for full master and journal data
evaluation or to create invoices.
P.O.S. is a high-performance sector-specific software developed especially by
PFREUNDT for Windows®. With P.O.S. your weighing data which you use to
control your weighing enterprise and to manage your company will be
processed immediately.

CWM Conveyor-belt scale
Using the CWM conveyor-belt scale PC program, you can hold up to
8 static belt scales in view on your computer monitor. At the same
time, the weighing frames that have been equipped with CAN
weighing modules are directly connected to the PCs, which have
likewise been equipped with CAN interfaces. Operation, visualization,
and evaluation – e.g. shift reports – can be carried out straight away
on the computer without any additional display electronics.
Your advantages:
• Access to the most important data at one glance
• Precise observation of each individual belt scale
• Administration of daily total,
shift total and current total
• Record of idle running and down times
• Zeroing of all belt scales with
one press of the button.
• Administration of shifts and shift models
• Daily and shift evaluations
• Administration of “virtual conveyor belts”

You will receive the CWM belt scale as a total system solution:
We provide you with the program already installed on a compact
and robust industrial PC for installation in the control cabinet or
if requested, in the control box. In this way, the system operates
independently and securely without being affected by other
software, which means that errors or program crashes can be
avoided.
The computer itself, with its robust components, is particularly
suitable to harsh user conditions. It offers a large color display
with a touch-screen user interface. The CAN interface for linking
the separate belt scales with CAN weighing modules and other
interfaces such as USB and WLAN are also part of the system
configuration.
