SIGMA Field Balancer SB-7705 Series

For balancing of flexible and rigid rotors.

• •As increasing rotational speed and downsizing of machinery, relative stiffness becomes lower and lower. It causes critical speed will exist in operating speed range.
  •Multi-speed multi-plane balancing method provides to defuse vibration at all operational rotating speed range.
  Conventional constant speed balancing function is available.

High accuracy and efficient balancing 1 to 4 plane balancing

• •Resolution of 0.001μm at up to 240,000min^–1 (SB-7705RS)
  •Low speed balancing down to 60min^-1model is available (SB-7705RL)
  •Measuring response is 2x fast by 2channel simultaneous measurement. (Compared to Sigma’s products)

After balancing vibration forecasting function

• High efficiency balancing can be performed by after balancing vibration forecasting function.

FFT analyzer is equipped as standard

• Frequency analysis and diagnostic of rolling bearing are included.

Vibration analysis functions

• •Unbalance vibration monitoring
  •Harmonic analysis
  •Overall amplitude monitoring

Lissajous display function

• •Lissajous at each rotational speed can be displayed continuously.
  •Locus of shaft center can be observed easily.

Documentation and archiving

• With our utility software, the measurement results can now be transferred directly onto your PC as CSV files and MS-Excel reports.
  •Measurement data can be stored in USB memory.
  •Measurement data can be printed out with mechanical dot printer. (-optional)
  •Screenshots can be stored in microSD memory or transferred to PC.

Touch screen color LCD

• •Easy operation with 5.7″ graphical color display
  •User-friendly procedure and help function

Unbalance correction by balance weights arrangement -optional

• •Unbalance can be corrected by arranging 2 or 3 balance weights on the circumference. This method is popular for balancing of grinding wheels.
  •If this method is applied to general industrial machinery, balance correction will be easily done only by rearrangement of balance weights, weight selection and/or fabrication is not needed.
  •SB-7705 series can be applied 1 plane(G) or 2 plane(GW) balancing.
