In 1985, Sigma Electronics has equipped the microprocessor in our Field Balancers foremost in the related field. We have made best efforts to deliver high quality and reliable Field Balancers to many customers as the pioneer of balancing instruments.

In 1988 we developed the original technology for Balance Measurement making use of Multivariable amount analytical method. It overwhelmed the whole of industry as the innovative Balance Measurement Machine because it could measure at wide range speed (60 to 400,000 min^-1) with high accuracy.

Furthermore in 2002 we developed SB-7700R that controlled harmful 3D(X,Y,Z) vibration occurred at every rotary speed of operation. This was an outstanding achievement for the first time in the industry and the primary factor why we were selected as one of “300 medium and smaller enterprises active at manufacturing” by Ministry of Economy, Trade and Industry.

Sigma Electronics has been producing Field Balancers and Balancing Machines, and we have contributed for various industries.
