Powerful field balancing functions
A unique feature allows operators up
to four measurement points to reduce error, providing complete versatility and high accuracy. A variety of
combinations are therefore possible
such as simultaneous horizontal and
vertical measurements, or two horizontal and two vertical measurements.
Correction locations can be identified
in polar or component form based on
the configuration of the rotor that is
being balanced. Rotors that have limited correction locations, such as a
fan, can be easily balanced with the
component correction feature. Users
are free to define the available correction locations on the rotor whether
they are equally or unequally spaced.
Archiving and documenting balancing results with BalancingReport
All balancing results can be recorded
in the Rotor Balancer along with a description of the machine, sensor position, date and time.
Measurement data can also be

supplied with the balancer. The BalancingReport software offers a
userfriendly environment to store
and manage unbalance data. Users
can create expert balancing reports
with Bode and Nyquist plots and cascade/waterfall charts. Measurement
results can also then be imported to
other programs in the Windows Office suite such as Word or Excel for
further processing.
