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.
