New form of field balancing that pursues
operation efficiency with special-purpose
softwarePortable Balancer
Model 7135A

SHOWA SOKKI CORPORATIONFrom field measurement to the output of work reports....
Model 7135A condenses functions and user-friendlinessthat enable efficient field balancing into a compact body.

(Simple balancing without
the need of removal

Model 7135A is a portablebalancer that can be easily
rebalanced with the target rotary
machine installed. The model
provides comprehensivebalancing when a dynamicbalancing test with a rotor alone
is impossible or after its
assembly is completed, andother mobility performance thatenables field work more
efficiently. It is automaticallytuned with a tracking filter, thus
facilitating measurement work.

)(

Outstandinguser-friendliness withspecial-purpose software)(

Special-purpose software "BalanceOne" enables very efficient work in
combination with a notebook PC.
Balancing can be easily done byoperating the keys while watching
the screen of the notebook PC.
What is more, the model comeswith a report format(Excel-compatible), thus enabling
the data to be used for reporting
purposes. All you have to do then isto go back to the office and print
them out. The work is now
complete. The model isoutstandingly user-friendly, with thecapability of integrated processing
from beginning to end.

Various handy functions
that increase its versatility
Model 7135 is compatible withrotary machines from 180 to
30,000 rpm as a field balancer. It
also allows users to select fromamong an acceleration sensor,speed sensor, and non-contact
displacement sensor. It
incorporates a vector output as
well, thus enabling polarogramswith an X-Y recorder and offeringhigh versatility as a vibration
gage, vibration monitor, andtachometer.

Rebalancing program “Balance One”
7135A-dedicated software that not only facilitates delicate rebalancing but
also provides a report format
It displays measurements sent from Model 7135A
on the screen whenever necessary. Pressing thecapture button causes the PC to capture the data,
while calculating and displaying the quantity ofcorrection weights and their locations. The operator
then has only to make entries on the keyboard
while watching the screen. He can then easily
perform delicate rebalancing.
Pressing the file button saves a history of tasks astext data just as they are performed. The data canbe read with Excel or other spreadsheet. Balance
One enables single-side correction, double-sidecorrection, component force calculation, and otheroperations.
• System requirement: Windows 95

Balance One automatically creates work
reports in a report format (Excel-compatible)
with data obtained by rebalancing. Clerical
work that is bothersome in many aspects canbe done very efficiently if only you haveBalance One.
