CAB 820 – The basic measuring unit for precise balancingSimple handling – High measuring accuracy – Progressive-proof concept
CAB 820Nothing but balance
The CAB 820 is our new basic measuring unit – and what
a unit! Even at this entry level you receive a first class
product combined with plenty of operating convenience,
and all of this at an excellent price/performance ratio.
This measuring unit is the right solution if you wish to
achieve your company's balancing targets quickly and
efficiently.
Because the CAB 820 is directly derived from our flagship
measuring unit, it contains many features from the more
expensive product. This starts with the extremely simple
and much praised operation through to the excellent
precision right up to its exceptionally high accuracy. This
product is perfect for all horizontal and vertical balancing
machines.
Planning for the future – simple to upgradeThe CAB 820 grows with the demands placed upon it. If your balancing tasks become more and more complex and demanding over time, you can easily up-grade your CAB 820 into our flagshipmeasuring unit CAB 920 SmartTouch. You then have a measuring unit with which can balance all conceivable technical rotor vari-ations – from low to high speed, from rigid to flexible, from vertical to horizontal – per-fectly, rapidly and extremely accurately.
Making new from oldThe CAB 820 is perfectly suited for the modernization of older horizontal and vertical balancing machines – also from other manufacturers. Using pre-assembled modernization kits, you can upgrade your old balancing machine quickly and easily and use the latest measuring technology.
The basis of the CAB 820 is a high performance and robust industrial PC with a TFT touch screen display. This guarantees the CAB 820 is able to carry out its work reliably and over a long lifetime even in harsh workshop operation conditions.
The CAB 820 operating system is Microsoft Windows and is therefore easy to integrate into company networks. Balancing results and protocols can therefore be readily exchanged with other departments, processed and evaluated.
Precision even in harsh conditions
Plenty of convenience from the start
All you need to operate this unit is your index finger – no
keyboard, no mouse. Using the robust touch screen, you
can control all functions of the measuring unit and thus
communicate with the balancing machine. Here we have
adapted all operating elements in size and function to
the touch screen philosophy. Large banks of keys and
clear interactive symbols, with direct input windows for
values and text, permit rapid and efficient work.
See what's going on
As with all of our measuring units, the CAB 820 utilizes
the tried and tested combination of unbalance display
with vector meters in combination with large, accurate
digital displays. This means that you have an overview
of the data for assessment of the unbalance condition of
your rotor on the screen.
When balancing, we understand everything you need for the task, using only two main pages and one option page for set up and display - clearly summarized and logically structured.
With the rotor set up; the first of the two main pages, you can set all the parameters required for balancing. Here, via the touch screen, you are guided with clear presentation, easily understandable symbols, expedient selection menus through the set up. On this page you
can also find the option menu with further functions – depending on the configuration of your measuring unit.
At the end of the measuring run the result is displayed on the second main page for you to view. In addition to the vector meters for unbalance display you can see the position and amount of the unbalance, as the results are also presented numerically with large digits.
Ingeniously easy due to our direct operating concept
The green tolerance circles
make it easy for the operator
to iden fy when the rotor
tolerance has been reached.
The current reading is shown in
red. The arrow shows the
correc on path from the last run
to the current run. This is espe‐
cially useful when material is
removed manually such as hand
grinding.
Rotor Setup Page
The geometric dimensions of
the rotor (a, b, c, r1 and r2)
tolerance, correc on method,
correc on loca on and drive
details are defined here and
balancing can begin by
selec ng the measure bu on. All rotor parameter informa on
necessary to immediately begin
balancing is on this one page.
Tolerance Display
Last Run Readout
The previous run is shown on the
vector display in plane 2 above
with a blue indica on.
This so ware op on accurately
iden fies the angle of unbalance.
As the operator manually turns the
rotor the orange line (as seen in plane
1) will turn blue when the angle of
unbalance has been reached (as seen
in plane 2).
Electronic Protractor Feature
The Electronic Protractor op on assures accurate loca ng of the heavy
or light spot for unbalance correc on. With it, a posi oning accuracy of
1 to 2 degrees is possible. This accuracy will substan ally enhance the
operator’s ability to achieve the balancing machine’s specified
unbalance reduc on ra o of 95 percent, and poten ally decrease the
required balancing me for any given part. Note that an unbalance
angle correc on error of only 6 degrees would create an overall
amount error in excess of 10 percent, resul ng in under correc on of
the rotor, and addi onal me to complete the balancing task.
