シグマ電子工業 Company Profile

Sigma is a specialized manufacturer of balance testing machines that suppress mechanical vibrations and contribute to the improvement of social environments.

Sigma's balance measurement method features the adoption of multivariate analysis techniques for detecting imbalances, allowing for high-precision measurements across a range from low to ultra-high rotational speeds. The field balancer that incorporates this measurement method has been in use since 1985, with cumulative production exceeding 8,000 units. Furthermore, after that, we began selling more precise balancing machines and condition monitoring devices that continuously monitor rotating machinery and detect signs of abnormalities, which also utilize the aforementioned measurement method. Over 30 years since the start of balancer production, Sigma's balancers are actively used across various industries.
